API594 WAFER CHECK VALVE DOUBLE DISC CF8M BODY EPDM SEAT 300LB
offers a wide range of double door wafer checks in cast iron, cast steel, stainless steel as well and steel and stainless alloys. We carry sizes ranging from 1 1/2" to 36" and pressure classes 125#, 150#, 300#, 600#, 900#, 1500#, and 2500#. They are available out of stock in wafer style and by special order in lug and flanged style.
-Economical, lightweight, compact design - significantly lighter and less expensive than comparable swing check valves
-Easy to install and maintain
-Smooth, spring assisted closing reduces water hammer
-Long legged springs allow plates to open and close without seat scrubbing
-Rugged Inconel spring is standard in all steel and stainless steel valves
-Manufactured to API 594 and tested to API 598
Connections suitable with flanges UNI EN 1092-1 PN 10 - 16
Standard API 594
Face to face length: EN 558-1 serie 16, API 609 BS 3135
Installation: horizontal / vertical with down-up flow direction. In horizontal position, the axis must be placed in vertical position. In vertical position, the plates must be opened in the same flow direction. Downstream, a piping of minimum length 5 times diameter, to be installed before the valve, and a pipe of minimum length 2 times diameter after the valve, to allow stabilization of flow and recovery. Installation between counterflanges.

The dual plate check valves wafer type are a compact kind of check valve. With a small face to face length and being wafer type, these dual plate check valves can be mounted directly between flanges and in accordance to many standard connections. The body is made in one piece only, in cast iron with disc in ductile iron, stainless steel or Al-bronze and spring in stainless steel, these parameters allow the dual plate check valves to be applied for several applications. The automatic mechanism of plate opening grants low water losses, and the spring avoids fluid hammer effect. Epoxy coated inside and outside, these check valves are suitable for potable water.
