Product Introduction
【Product use】
H61H, H61Y type 800 (Lb) socket welded forged steel check valve has three body cover connection design forms.The first is the bolted valve cover: for a valve designed in this design form, the valve body and the valve cover are connected with bolts and nuts, and the wound gasket (made of 316 clamp flexible graphite) is sealed.Metal ring connections can also be used when customers have special requirements.The second design form is the welded valve cover. For a valve in this design form, the valve body and the valve cover are threaded and sealed with full welding.When customers have special requirements, through-welding connections can also be used.The third is the pressure self-tightening valve cover. The valve designed according to this design form has a threaded connection between the valve body and the valve cover, and the internal pressure is sealed with a self-sealing ring.
