AIR VALVE
DOUBLE ORIFICE STANDARD AIR VALVE
Combination Air Valves
Model No.: 455 – c/w Integral Isolating Valve (Standard Type)
Model No.: 455A – Isolating Sluice Valve Type

  1. 1
    Description

    LYE Double Orifice Standard Air Valves combined features of small & large orifice air valves for automatically releasing small pockets of accumulated air, “air pocket” from a pipeline which system operate under pressure exceeding atmospheric pressure, and as well as exhausting large quantities of air automatically during pipeline filling & admitting when the internal pressure in the pipeline drop below atmospheric pressure. LYE Double Orifice Standard Air Valve complete with integral isolating valve designs for easy valve maintenance.
