Ball Float Vent Valve
Normal Size: 1/2”~8”
Pressure rating: 150 LB~900 LB
Connection: Flange, B-Weld, S-Weld
Materials: WCB, LCB, LCC, CF8, CF8M, CF3, CF3M, A105, LF2, F304, F 316, F304L, F316L, F51.
Operation Style: Lever, Gearbox, Pneumatic, Electric Actuator
Design Features: Anti blow-out stem, Antistatic device, Fire safe design API 607 Soft Seat or metal seat, Side entry. The floating ball valve has the function of Automatic body cavity relief, it doesn’t damage the seat sealing. The un-normal pressure which in the floating ball valve body will be released into the upstream pipe directly, it doesn't damage to the sealing of the downstream seat. The operating torque is low. The self-lubricated bearings are installed at the friction of stem, en-length its life, make the operation more flexible, reduce its torque.
