Trunnion Mounted Ball Valve

Hot sale quality Trunnion Mounted Ball Valve with Low Price made in China. Milestone is Trunnion Mounted Ball Valve manufacturer and supplier in China.  The trunnion ball valve is a form of quarter-turn valve which uses a hollow, perforated and fixed ball to control flow through it. 

A trunnion mounted valve means that the ball is constrained by bearings and is only allowed to rotate, the majority of the hydraulic load is supported by the System constraints, resulting in low bearing pressure and no shaft fatigue. The line pressure drives the upstream seat against the stationary ball so that the line pressure forces the upstream seat onto the ball causing it to seal. The mechanical anchoring of the ball absorbs the thrust from the line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure operating torque remains low.

What are the features of the Trunnion Mounted Ball Valve

a) .Standard double block sealing performance.
b) .Full die forged structure for all pressure containing parts.
c) .Flanged valves are provided with flanged integral with closure member.
d). High quality stem gasket for reliable tightness and low emission performance.
e) Use of low seat-ball friction materials and surface.
