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 butt-welding end for piping flexibility.
D)Body-to-Cover Joint A male and female joint or tongue and groove joint are 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 is available with all swing check valves.	F)Seat Rings Separate heavy-duty, full ported rings for easy maintenance. Screwed or welded connection into body.
G)HCU weighted mechanical accumulator This design can be used to either dampen or assist in closing the check valve disc depending on orientation. by using the hydraulic control unit to buffer the action of the disc, the valve opens at lower flow rates.
