Main Feature:
Design features of metal to metal sealed ball valve
Except for such features as wrong operation prevention, stem blow-out proof, mounting, pad provided, the metal to metal sealed ball valves made by our company's possess the following unique features.
Valve stuck under high temperature prevented
In the case of high temperature working condition, the valve seat and ball would easily get stuck due to heat expansion, and the valve could not be open. Metal to metal sealed ball valves made by our company's are employ the patented design of bevelling spring loading, which would absorb the heat expansion of parts caused by the bevelling spring. So it is ensured that the valve would not get stuck and be opened and closed easily in the case of high temperature condition.
An entire fire safe structure
The metal to metal sealed structure has been adopted for the valve sealing surface design. Packing is so designed with graphite, and gasket is so designed with stainless steel, plus graphite that the valve can assure reliable tightness even under fire condition.
Natural anti-static structure
Metal to metal sealed ball valve with its bodyseat, ball, other metal parts, and so forth, closely contact with each other, having naturally formed a static electricity passage. In this respect, there is no need to provide special anti-static device.
Double-block and bleed function
Our company's metal to metal sealed trunnion ball valve is in general of the front ball sealing structure. Actually, two seats of the metal to metal sealed trunnion ball valve can both cut off separately the medium at inlet and outlet to realize double-block function. When the valve is closed, the body vavity and both the bore ends can be blocked with each other even if both ends of the valve are under pressure at the same time. Whereas the medium left in the body cavity may relieve through the relief valve.
Our company's metal to metal sealed floating ball valve is of behind ball sealing structure, employing in general single direction tightness. The flow direction is indicated on the valve body. If specially required by customers, Our's bi-direction sealing design may be selected.
