Flanged Soft-Seal Gate Valve
Flanged Soft-Seal Gate Valve
Flanged Soft Seal Gate Valve for Municipal Pipeline
The Flanged Soft-Seal Gate Valveis designed for reliable isolation in pipeline systems that require excellent sealing performance, low flow resistance, and stable operation. Its soft-seal structure typically uses elastic sealing materials such as EPDM or NBR, allowing the valve disc to fit tightly with the seat and achieve near-zero leakage after closing. In the open position, the full-bore flow path helps minimize pressure loss and supports efficient fluid transmission.
Product Features and Advantages
·Excellent sealing performance and zero leakage : The combination of valve disc and soft sealing seat can achieve elastic sealing, and there is almost zero leakage after closing.
·Full-bore design / Low flow resistance : When opened, there is no obstruction inside the valve, the flow path is directly connected to the pipeline, and the pressure loss is minimal.
·Anti-corrosion coating/corrosion resistance : An epoxy anti-corrosion coating can be sprayed on the inside and outside of thegate valvebody to improve corrosion resistance and service life.
·Suitable for a variety of media : tap water, neutral liquids, low-pressure steam, etc., applicable to municipal water supply, building water supply and drainage, HVAC systems, industrial clean water systems, etc.
·Simple installation and maintenance : Traditional handwheel operation, mature and stable structure, suitable for general engineering projects.
Size Specifications and Standards
· Nominal diameter: DN50–DN600 (2"–24") is the standard range.
· Pressure rating: PN16 (PN10/PN25 can be customized for some applications) .
· Standards: Flanges and boreholes conform to BS EN 1092-2 , valve body structure and dimensions conform to BS 5163 / BS EN 558-1 , and pressure testing conforms to BS EN 12266-2003 .
