Detailed

Brief Introduction

AX742X Safety relief valve/ Pressure Holding valve is mainly used for the water supply system of fire control and others, to avoid overpressure, or holding fire control water supply system pressure. After fire control pump closing, it can also reduce water hammer damage. It can also been used for water hammer device of large water supply system. This valve is composed of main valve, needle adjust valve, pilot valve, ball valve and pipe system. Main valve adopts full bore, straight way and streamline design, low head loss. Main valve could be diaphragm type or piston type.
