Frequently asked questions
Here are some common questions about our product.
A top entry design allows access to the valve's internal components from the top, making inspection and maintenance easier without requiring complete removal of the valve from the pipeline.
Yes. Their top entry construction allows maintenance and servicing of key internal components while the valve remains installed in the pipeline, helping reduce maintenance time and operational disruption.
Top entry ball valves are well suited to offshore applications because their maintenance friendly design can simplify servicing where access, space and equipment availability may be limited.
A full bore valve provides a flow passage close to the pipeline's internal diameter, helping minimize pressure loss and turbulence. A reduced bore valve has a smaller flow passage and may be selected where a more compact or application-specific design is required.
A self-relieving seat design helps release excessive pressure that may build up within the valve cavity, supporting safe and reliable operation under changing pressure conditions.
Depending on the valve configuration, safety features can include anti-blowout stems, anti-static devices, fire-safe construction and double block and bleed capability for demanding industrial applications.
