Forged steel globe valve has three types of cover design. The first is a bolt type valve cover, according to the design of the design of the valve, the valve body and the valve cover with a bolt and nut connection, spiral wound gasket (316 clip flexible graphite manufacturing) seal. Customers have special requirements can also be used to connect metal ring. Second design forms are welded valve cover, according to the design of the form of the valve, the valve body and valve cover with a threaded connection, the whole welding seal. Customers have special requirements can also be fully welded through the connection. The third is a pressure self tightening type valve cover, according to the design of the design of the valve, the valve body and valve cover with a threaded connection, internal pressure self sealing ring.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
