A20B Pressure Reducing Valve & Low Flow Rate Bypass

A20B Pressure Reducing Valve & Low Flow Rate Bypass

Spec Sheet: A20B Spec Sheet

Installation, Operating, and Maintenance Manual: Alpine ACV BT115-LF-IOM-Manual-Pressure reducing with low flow by-pass

Alpine Catalogue: ALPINE ACV

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.
