MAIN FEATURES

Fire-SaFe Test
Approved trunnion ball valves are designed in accordance with API 607 & API SPEC 6FA. When non-metal seats are destroyed in a fire, the medium pressure push the upstream seat into the ball to cut off the line fluid and prevent internal leakage due to a secondary metal-to-metal seals. When the first soft seal is damaged, body, bonnet, stem-gasket can reach sealing function and prevent external fluid leakage.

Double body Gasket
All trunnion ball valves are equipped with two body gasket. The first body gasket is in soft material and the second in graphite (if not otherwise required), this combination assures the best seal characteristic in whatever corrosive service as well give fire safe design.
ANTi-static device In order to prevent static electricity which may light the fluid, static-conduction spring is set between the stem trunnion and the ball.

AnTi blow-ouT prooF STem
The stem is designed with integral T-Type shoulder to provide blow-out proof effectively. The design assures that the stem can not be blown out of the valve in the case of the packing being removed while the valve is under pressure.

CONTROLLED STEM & STUFFING BOX FINISH
Stem and stuffing box finish machining is a key point of control. The stem is made by cold rolling and stem surface finish is controlled by Ra=0.4, which can reduce friction for stem moving and ensure the seal. The stuffing box surface is controlled within Ra=1.6 for better sealing performance.
