A20B Pressure Reducing Valve & Low Flow Rate Bypass
A20B Pressure Reducing Valve & Low Flow Rate Bypass
Spec Sheet: DNS-A20B Pressure Reducing Valve + Low Flow Rate Bypass-V1
Installation, Operating, and Maintenance Manual: Available on request.
Certification: WRAS
The A20B is a pressure-reducing valve with a low flow rate bypass pilot. It gives a stable fixed outlet pressure
during a normal flow rate. When the flow rate is very small, the main valve will close and water will flow through the bypass pilot to avoid valve vibration.
