Product Details
Trunnion support stabilizes the ball at two points and reduces operating torque on large-bore or higher-pressure valves. Stainless steel construction is selected for corrosion resistance in process and pipeline installations.

FAQ
How should this valve be configured for the application?
Confirm body alloy, bore, flange face, fire-safe requirement and service compatibility before quotation. Final selection must be verified against the actual medium, pressure, temperature and applicable piping standard.
Can this ball valve be automated?
Gear operation is typical; pneumatic, hydraulic and electric packages are available by torque and fail-safe requirement.
What documents can be supplied for a project order?
Material certificate, hydrostatic test record, dimensional drawing, packing list and certificate of conformity can be provided when specified in the order.
Do pressure and temperature ratings apply to every configuration?
No. Ratings depend on the selected body material, seat, packing, end connection and service fluid. Confirm the final pressure-temperature limit with the selected supplier before purchase.
