PTFE Lined Wafer Check Valve
MVS fabricates Fully PTFE Lined Wafer Check Valve in Single Disk Design. Swing Type PTFE Lined Wafer Check Valve is reasonable to mount between two spines of ANSI B 16.5, and are great for use in completely lined funneling framework in erosion application. This valve can be mount in one or the other heading.
Swing Type PTFE Lined wafer check valve has a completely PFA fluoropolymer embodied one piece circle and pivot and PFA lined body. It has a held circle configuration beating the establishment issues related with 2 piece plans. The calculated seat permits the valve to be introduced in both level and vertical applications. The non return valve has extremely straightforward activity permitting stream just a single way through the valve.
The PTFE Lined Wafer Check Valves is accessible in sizes 1"NB up to 12" NB in a wafer style design and is obviously fit to slurry obligations as the circle swings uninhibitedly from the drag.
