Brief Introduction

LZ500X Safety Pressure Relief Valve/ Pressure Sustaining valve is mainly used for fire control and other water supply system, to avoid system over pressure or maintain water supply system pressure. When pump closed, it can reduce water hammer. It can also been used in water hammer device in large water supply system. This valve is composed of main valve, needle adjust valve, pilot valve, ball valve and pipe system. The valve sets water supply system pressure by setting pilot valve spring pressure and needle valve open degree, and stabilize water supply system pressure with the feedback action fro pipe system and control room, no other device or energy needed, easy to maintain, pressure control is precise, performance is reliable
