Expanding Gate Valve -- Double Block Bleed WCB
Expanding parallel gate valves with mechanically expanding discs that provide true double block and bleed isolation in a single valve body. The cam-driven expansion mechanism forces parallel discs against seats independently of line pressure, ensuring reliable sealing even at low or fluctuating pressures. Gate retracts before movement to minimise seat wear and extend service life.
