API6D Through Conduit Slab WC6 PSB Gate Valve 14IN 1500LB

Features

-Low pressure drop:slab gate structure with full-bore diversion hol.When fully open and resulting in a extremly low energy loss.
-Automatic Pressure Relief:With floating design seat(tightly against the gate to achievepressure self-enhanced sealing), O-ring preload + medium pressure self-sealing,it can automaticly release of valve cavity overpressure.
-Pigging:Through conduit gate is equipped with a diversion hole; when fully open, it is piggable with minimal flow resistance.Non-through conduit gate has no diversion hole, cannot be pigged, and is suitable for shut-off scenarios that do not require pigging.
-Bidirectional Sealing: Regardless of the direction of medium inflow, the seats on both sides can independently form an effective seal.
