Pressure Reducing Valve- BV421 Series

The BV421 Pressure Reducing Valve, from the Belven - Stallion range, is designed to set, adjust and maintain the downstream pipeline pressure, regardless of the variation in the upstream pressure.

In this model, the Belven - Stallion (Main Valve) BV400 coupled with the pressure reducing pilot BV401, is designed to control facilitated the fluctuating upstream pressure to a constant lower downstream pressure. The control is by the normally open pressure reducing pilot BV401. When the BV401 is open, it allows liquid to flow out of the Stallion's cover chamber. When it is closed, it allows the liquid to fill the stallion's cover chamber.

Normally a decrease in downstream pressure causes the valve to open, consequently raising the pressure and vice versa. The BV421 comes with WRAS approved coating and is suitable for all potable Water applications.
