Air Vent Valve IAV-N300
- Categories
- Air Vent Valve
- Body Material
- Ductile Iron
Description
Specification Standards :
- Design standard : BS EN 1074-4
- Threaded end connection : ANSI B1.20.1 / NPT
- Standard for pressure test : BS EN 12266
Features :
- Simple float operated valve that allows bleeding of air from piping systems without allowing water (liquid) to escape.
- When the valve chamber is empty the float remains in the lower position. In this position the valve is open & thus allows air to escape. As water enters
the chamber it lifts the float. Finally when chamber is full of water the float is in upper position and the valve is closed thus preventing water from leaking out. - The float is made from stainless steel for longer service life.
- The rubber seat offers good sealing to prevent leakage.
Application :
For general and industrial services
