Forged as a single unit to eliminate defects like sand holes or air pockets common in die-cast bodies. The thickened wall enhances pressure resistance and meets material standards for lead-free water supply and fire piping networks, offering resistance to limescale and electrochemical corrosion.
One end features precision standard male threads with uniform thread profiles and high coaxiality, ensuring seamless compatibility with all standard threaded fittings. The other end features an integrated, extended press-fit sleeve; combined with a stainless steel locking ring and a dual-layer aging-resistant silicone seal, it creates a tight, secure grip after hydraulic pressing, effectively preventing static water leakage.
The compact butterfly design saves space in tight areas like pipe shafts and ceiling voids. It features a non-slip surface texture and allows for full open/close switching with just a 90-degree turn. The distinctive handle shape ensures quick visual identification of the valve's status during network inspections.
Features a mirror-finished, solid chrome-plated ball core with a full-bore (non-reduced) flow structure; utilizes thickened PTFE seats for tight bi-directional sealing; the stem incorporates a built-in anti-blowout shoulder design to withstand instantaneous high-pressure surges and prevent seizing during prolonged periods of inactivity.
Covers the six mainstream pipe sizes: DN15, DN20, DN25, DN32, DN40, and DN50; each valve is individually laser-marked with a batch code and comes with factory-matched replacement press-fit rings and silicone gaskets.
This Press Type Butterfly Handle Male Thread Brass Ball Valve combines press-fit and male-threaded connection methods, enabling seamless integration between thin-walled stainless steel piping and threaded equipment or fittings. It eliminates the need for additional adapters, reduces potential leakage points, and allows a single valve model to suit two different connection scenarios, thereby simplifying inventory management.
The press-fit connection is mechanically secured using specialized hydraulic tools, requiring no welding or pipe threading. This makes it ideal for environments where "hot work" (open flames) is prohibited—such as high-end building interiors, enclosed mechanical rooms, and fire safety retrofit projects—while significantly reducing on-site assembly time and minimizing rework costs caused by human error.
Unlike traditional long handles that require significant clearance, the compact butterfly handle fits easily into restricted installation areas such as ceiling plenums, vertical pipe shafts, and cramped equipment enclosures. The 90° short-stroke operation allows for quick, effortless control during emergencies (e.g., fires or pipe failures), ensures high visibility for inspections, and reduces the risk of accidental operation.
The thickened forged valve body stably withstands PN16 nominal pressure, resisting instantaneous high-pressure surges from sprinkler or boiler system start-stop cycles. A triple-seal design—combining a stainless steel compression ring, a dual-layer silicone seal, and a PTFE valve seat—ensures resistance to aging and deformation during prolonged static water immersion and thermal cycling, effectively eliminating fire safety risks associated with hidden, slow seepage.
A dedicated locking shoulder at the base of the stem secures its travel range. This prevents stem ejection, leakage at the seal, or jamming during periods of prolonged static standby or frequent water pressure fluctuations in the fire protection network, significantly reducing the frequency of future maintenance.
Ideal for systems using thin-walled stainless steel main pipes with press-fit connections. The threaded end of the valve connects directly to threaded sprinkler heads at branch terminals—eliminating the need for adapters or welding—making it perfect for new fire protection installations in high-end residential units and shopping complexes.
Suitable for connecting thin-walled stainless steel underfloor heating mains (via press-fit) to manifolds and circulation pumps (via threaded connections). The butterfly handle design fits well in confined spaces like underfloor heating cabinets or ceiling-mounted piping, while the valve withstands long-term thermal cycling.
Ideal for sites where hot work (welding) is not feasible. The press-fit end allows for the rapid replacement of failed valves, while the threaded end connects to existing threaded piping; this avoids the need to dismantle embedded pipes, drastically reducing construction complexity and costs.
Connects threaded equipment outlets with stainless steel circulation piping; the dual-interface valve ensures seamless integration between the two pipe types. The lead-free valve body meets safety standards for potable water supply, and the full-bore design ensures stable flow rates.
- DN15/DN20: Underfloor heating for small residential units and sprinkler branch lines for single-story shops; features small diameters and tight installation spaces, where the butterfly handle offers a clear operational advantage. DN25/DN32: Sprinkler risers for high-rise residential buildings and main lines for individual unit underfloor heating; standard diameters for commercial HVAC systems and mainstream specifications for project inventory. DN40/DN50: Central sprinkler mains for shopping malls and office buildings, as well as main circulation lines for large-scale air-source heat pump systems; designed for high-flow, high-pressure conditions, featuring a thickened valve body for superior pressure resistance.
- Single-Connection Press-fit Ball Valve: Compatible only with stainless steel piping; cannot connect directly to threaded equipment without adapters, which increases the risk of leakage. Single-Connection Male-threaded Ball Valve: Requires pipe threading; involves on-site hot work and multiple processing steps, making installation difficult in tight piping spaces. This Dual-Interface Composite Ball Valve: Compatible with both stainless steel press-fit assembly and threaded equipment connections; requires no welding or additional adapters, balancing installation efficiency with piping compatibility.
- Occupies significant lateral space; in suspended ceilings or narrow pipe shafts, it may be obstructed by insulation or sheet metal, preventing proper opening and closing. Compact Butterfly Handle: Features a compact overall profile allowing the valve body to be fully encased in insulation, with only the handle slightly exposed; ensures unobstructed operation in tight, enclosed spaces and enables faster emergency water shut-off.
HPb59-1 brass billets undergo batch-by-batch spectral analysis to strictly control lead-free, pressure-resistance, and dezincification-resistance metrics. Stainless steel press-fit rings and silicone gaskets undergo separate high-pressure hydrostatic testing and high/low-temperature cycling aging tests to screen out components prone to premature failure.
Every Press Type Butterfly Handle Male Thread Brass Ball Valve undergoes high-pressure hydrostatic shell testing, bubble-based airtightness testing, and 10,000-cycle opening/closing durability testing to fully verify pressure limits, sealing stability, and operational longevity.
Coaxiality and thread fit are individually inspected for the male threads; flaw detection is performed on the press-fitting sleeve welds and the fit of the compression ring. These measures specifically prevent common pipeline failures such as thread leakage and pipe detachment.
Each valve is laser-marked with a unique batch code. Data from all production stages—forging, machining, component assembly, and final inspection—is permanently archived, enabling rapid traceability and solution identification should any quality issues arise.
Professional technicians provide comprehensive hands-on guidance, covering stainless steel pipe cutting, hydraulic press-fitting pressure control, male thread assembly standards, sectional high-pressure testing of the piping network, and specific troubleshooting protocols for press-fit and threaded connections, thereby minimizing rework during on-site commissioning.
A multilingual customer service team accommodates global time zones, ensuring rapid responses to inquiries regarding product selection for specific operating conditions, bulk order status updates, and after-sales support requests from overseas contractors and plumbing wholesalers, facilitating seamless cross-border communication.

A: Standard single-press ball valves connect only to stainless steel piping; connecting to threaded sprinkler heads or circulation pumps requires adapters, which introduces additional potential leak points. Pure male-thread ball valves require on-site threading, a process that is cumbersome and poses fire hazards due to hot work. This product features an integrated dual-interface design, allowing a single valve to connect to two different piping types without adapters or welding. This reduces inventory variety, simplifies on-site assembly, lowers the risk of pipeline leaks, and is ideal for both new construction and renovation projects involving hybrid piping systems.
A: No. The product features a high-toughness stainless steel locking ring and a dual-layer, aging-resistant silicone seal. After hydraulic press-fitting, the locking ring engages uniformly with the stainless steel pipe wall, distributing stress evenly to prevent deformation caused by localized pressure points. The silicone seal has undergone thousands of hours of static water immersion aging tests, making it suitable for the long-term static conditions of fire protection piping networks. Additionally, every press-fit connection undergoes non-destructive testing before leaving the factory, effectively eliminating fire safety risks such as pipe detachment or slow leakage at the source.
A: It is fully compatible. The valve body is forged from thickened HPb59-1 brass as a single unit and undergoes destructive PN16 high-pressure testing before shipment. It reliably withstands the steady pressure of high-rise sprinkler systems and the transient high-pressure surges caused by pump start-stop cycles, meeting both domestic and international acceptance standards for fire protection piping projects.
A: No. The butterfly handle is compact, allowing the press-fit section of the valve body to be fully wrapped in insulation material while only the handle extends slightly outward, requiring minimal operating clearance. Its 90° short-stroke design enables switching between open and closed states with a simple flick, ensuring unobstructed operation within standard pipe shaft and ceiling void clearances without interference from sheet metal or insulation.
