Flanged Soft-Seal Gate Valve

Flanged Soft Seal Gate Valve for Municipal Pipeline

The Flanged Soft-Seal Gate Valve is 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 the gate valve body 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.
