Z41h-16c Dn400 Wcb Flange Type Manual High Temperature Resistant Gate Valve
When the valve is closed, rely on external force to force the gate plate to the seat, to ensure the sealing surface sealing, which is forced to seal. Domestic high-pressure gate valve used to automatically seal, low-pressure gate valve are used to force the sealing principle.
