BFS/BTS40~400
PRESSURE SUSTAINING VALVE
Description
1. The BFS pressure sustaining valve maintains the preset inlet pressure, unaffected by the outlet pressure.
2. The unique U-shaped seal provides a longer maintenance-free lifespan, and the piston design delivers the highest flow capacity compared to any other pressure sustaining valve on the market.
3. When installed in the user's distribution pipeline, the pressure sustaining valve ensures the minimum operating pressure in the water supply pipe, keeping upstream and downstream water pressure balanced. It maintains a constant pressure within the pipe at all times.
4. When installed in a water supply zone, the pressure sustaining valve maintains the maximum operating pressure in the pipe.
