3D’s standard side entry trunnion ball valves are designed to API’s highest standards. The 3-piece design offers maximum protection against line pressure and thermal distortion with long life and trouble-free performance. And supply its products to the Crude Oil Transport and Processing, Power Engineering, Water Supply Systems and Process Industries.


Trunnion mounted stems absorb the thrust from line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure, operating torque stays low.


3D ball valves have been fire tested and can be supplied to API 607.The soft seat inserts, irrespective of their materials, will possibly fail when subjected to sudden high temperature conditions. We provide fire-safe design which may substantially prevent leakages through seals when damaged by high temperature.

The seats are of both-side-sealing type, which means that they seal both on the upstream or downstream side of the ball valve and inside the valve. Whether in the open or closed position, pressure on each side of the ball is blocked from the body cavity by the seat rings engineered to self relieve. No pressure build up can occur in to body drained through the body port




MAIN FEATURES:

The side entry trunnion mounted ball valve has been designed two piece body type or three piece body type and with two floating seats, which are movable under the pressure of medium. Under the bottom of seats, seat pre-loading springs are positioned to ensure two floating seats can attach the ball’s surface tightly, other more, pressure of medium also can push seats to attach ball tightly to ensure sealing more reliable.


The trunnion ball valve is equipped with a movable seat seal ring which can generate displacement under the pressure of medium. In case that any medium pressure exists, the pressure will press the valve seat seal ring onto the ball tightly, guaranteeing the sealing performance of the ball valve.
