Frequently Asked Questions

What is the advantage of a three-piece split body design?

The three-piece split body design allows for easy disassembly and maintenance without removing the valve from the pipeline. It provides superior structural integrity for severe service conditions.

How does the anti-blowout stem design improve safety?

The anti-blowout stem is engineered with a multi-stage retention structure that prevents the stem from being ejected under high pressure, ensuring a leak-free seal in demanding environments.

What does fire-safe and anti-static design mean?

Fire-safe design ensures sealing integrity during a fire event using secondary metal seats. Anti-static construction dissipates static charges to prevent ignition in hazardous environments.

Why use a trunnion mounted design for high pressure?

The ball is anchored by bearings, so pipeline pressure does not push the ball against the downstream seat. This reduces operating torque and wear at high pressures like Class 2500.

In what applications is a metal-seated hard seal recommended?

It is recommended for high temperatures, high pressures, abrasive media, or frequent cycling where soft seats would wear prematurely, such as in steam or slurry transport.

Can the valve be upgraded to electric actuation?

Yes. The valve features a standardized mounting interface (ISO 5211) that allows for seamless integration of electric or pneumatic actuators for automated control.
