Low-torque Operation
Regardless of size or pressure rating, every fully welded ball valve is trunnion mounted. High-strength forged stems are located in PTFE impregnated stainless steels bearings for smooth operation. 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.
Double Block-and-bleed
Whether in the fully open or fully closed position,pressure on each side of the ball is blocked from the body cavity by the seat ring. The body cavity can then be bled down or drained through the body port. When you block-and-bleed a fully welded ball valve, the following can be accomplished:
Test Valve Integrity
When the valve body is vented, the seat seal'sintegrity is verified. This test can be performed with the valve open or closed prior to facility maintenance. By verifying valve integrity,unforeseen valve leakage can be prevented.
Secondary Seat Seal
The sealant injection system provides a fast, simple way of restoring tight shutoff if any foreign object should damage the sealing surfaces. The injection system also can be used for routine flushing of the seat ring area in services where this may be required
