Walworth Ball Valve

Ball Valve

Trunnion Ball

Ball Valves mounted over a ball, also called Trunnion Ball Valves are mainly used in the petroleum industry; extraction and refinement of products like oil and natural gas. These valves provide confidence in service given their double blockage and purge function.
The engineering development of WALWORTH products is bound to API 6D, ISO 14313, ASME B16.34 and ASME VIII standards. Different classes of pressure are available, from 150 to 2500, and can be manufactured in though conduit or piggable. The later facilitates the pass of cleaning and calibration tools for pipe systems. Also, it avoids turbulence and pressure drops.

Ball check valves

Ball check valves are generally used to protect pumps or similar equipment whilst allowing the passage of flow in only one direction and preventing the return of it due to backpressure.
Ball check valves can be used with high viscosity fluids. This type of valve has an arrow in the body’s exterior to indicate the direction in which it must be installed so the flow can be controlled.

Y-pattern ball check valves

Y-pattern ball check valves are generally used to protect pumps or similar equipment whilst allowing the passage of flow in only one direction and preventing the return of it due to backpressure. They are also used when the CV needs to be increased.
