Product Description

Forged steel bellows valves are available in two valve cover designs. The first is the bolt-type valve cover, according to this design form of the valve, the valve body and the valve cover are connected with bolts and nuts, and the winding gasket (304L clamp flexible graphite manufacturing) is sealed. When customers have special requirements, metal rings can also be used to connect. The second design form is welded valve cover. According to this design form of the valve, the valve body and the valve cover with thread connection, fully welded seal. Full welding of the Contrived connection may also be used when the customer has special requirements.

Bellows valve design Structural features:
Bellows valve in accordance with APl602. MSS-SP-118.B55352 and ANSI B16.34, inspection and test according to APl598. The following structures are

used according to MSS-SP-25:
self-centering platen press sleeve
bolt connection, wound gasket sealed valve cover and threaded connection, all-welded sealed valve cover
integral on the seal seat
socket in accordance with ASME B16.11
