Description

Features:

• A short face-to-face dimension
• The spring loaded double disc design creates a low cracking pressure and allows for the valve discs to close prior to any flow reversal minimizing water hammer and/or surges in the media
• Tension on the specially designed spring with extended spring legs allows the disc center section to lift off the seat prior to the outside edge opening preventing seat wear in the center "heel" section of the seating surface
• Standard elastomeric seats can produce zero leakage when correctly specified, loaded and installed
• Retainerless design check valves have no body penetrations eliminating potential leak paths
• Allows for interchangeability of the hinge pin and stop pin
• Field serviceable without the need for special tools
• 316 stainless steel disc, Buna-N O-ring seat and Inconel X-750 spring

Applications:

Flow reversal solutions for liquid and gas applications where protection from flow reversal in a pipeline is required
