8″ 150LB WCB API Swing Check Valve

Short Description:

API Swing Check Valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position. Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.

A)Eyebolt For 150Lb-8″,300Lb-8″, 600Lb-6″,900Lb/1500Lb/ 2500Lb-4″ & over.	B)BC Bolted cover. welded cover and pressure seal bonnet in services requiring frequent cycling or with high pressure/temperature variations.	C)End Connections A choice of flanged, RTJ flanged or buttwelding end for piping flexibility.
D)Body-to-Cover Joint A male and female joint or tongue and groove joint is used 150Lb to 600Lb valves. Ring joint is used in the body to cover connection in 900Lb & higher rated valve.	E)Outside Lever And Weight All external hinge pin swing check valves 12″ and smaller are available with an optional outside lever and weight, internal hinge available with all swing check valves.	F)Seat Rings Separate heavy duty, full ported rings for easy maintenance. Screwed or welded connectioninto body.
G)HCU weighted mechanical accumulator This design can be used to either dampen or assist closing of the check valve disc depending on orientation. by using the hydraulic control unit to buffer action the disc, the valve opens at lower flow rates.
