FM463 DN50
An iron check valve with spring-assisted closure.
Application
- Suitable for use on Group 2 liquids only, as defined by the Pressure Equipment Directive 2014/68/EU.
- Suitable for installation in vertical and horizontal pipelines.
Description
An iron check valve with spring-assisted closure.
Features and benefits:
- Check valves permit flow in one direction only and close automatically if flow reverses, depending upon pressure and velocity of flow to perform the functions of the opening and closing.
- Non-Slam design as a result of rubber seat and spring-assisted closure.
- EPDM rubber seat to facilitate quiet operation and improve disk seating.
- Eyebolt tapped holes in sizes DN200 and above, to fit bolts to BS EN ISO 3226:2010 (eyebolts are not supplied with product).
- Design and construction lends itself to pump duty applications.
