Product Description

Product Description

The vacuum relief valves are normally closed. But when installed at points where water column separation can occur, both orifices open admitting air into pipeline, then instantly close to trap air and thereby cushioning re-joining of the water column. In this manner severe pressure surge/water hammer is prevented as the system returns to normal operation.

Product Features

  • Vacuum Relief for piping system
  • Prevent Water Hammer & Vortex Phenomena
  • Prevent overflowing
  • Increase efficiency of water transport in a piping
  • Easily cleaning the inside of air valve

Product Specifications

 Set Vacuum :  - Minimum 150 mmH2O (0.213 psig, 0.015 kg/cm2) / Maximum 9000 mmH2O (12.8 psig, 0.9 kg/cm2)
 Large orifice : From 1-in (25-mm)  To 12-in (300-mm)
 Flange : From 1/2-in (13-mm)  To 12-in (300-mm)
- ANSI, NPT, PT flange connection is available. Other flanges are to be discussed with technical sales person.

Product Use

For critical applications where vacuum protection is a must or water column separation is predicted, a vacuum relief valve is used. The vacuum Relief Valve is mounted at critical pipeline, high points, penstocks, or tanks and allows for rapid inflow of atmospheric air to reduce vacuum conditions in piping systems
