RF Flanged Fixed Trunnion Mounted Stainless Steel Ball Valves Class
Product Description:
The trunnion ball valve with the B I-sealing design structure, i.
e. Seat sealing in front of the ball and seat sealing behind the
ball, thus the reliable sealing of the valve is ensured because the
valve can perform normally even if one of the effective sealing
designs becomes lost due to the abnormal condition. Regarding the
seat in front of the ball, the piston effect formed by the are a
difference between D1 and D2, plus the pre-tightened force of a
spring would cause the seat in front of the ball by the pressure
difference of the medium before and after the valve to touch the
ball closely to form the tightness, of which the sealing force will
become bigger as the pressure difference gets higher.
Blow-out proof stem
Blow-out proof structure is provited with for the stem, which is
positioned by the up-end cap and screw, being guaranteed not to be
blown-out by the medium even if at abnormal risen pressure in the
cavity.
Anti-static design
The ball of the trunnion ball valve gets close contact with each
othe through the trunnion, adjusting cushion, and down-end cap, the
passage of static electricity thus forms together with the valve,
which may lead the static electricity caused by sparks generated by
friction between the ball and seat during on and off performance to
the ground to prevent the possible risk of fire or explosion.
