Product overview

Certification and inspection documents

Service conditions

A ball valve opens or closes the pipeline by rotating a ported ball. Port geometry, seats and stem sealing determine its operating behavior. Selection should consider differential pressure, fluid cleanliness and cycling duty together.

Construction and description

Match the operator to the valve load and site operating method. Manual operation needs accessible clearance. Frequent cycling or remote control also calls for assessment of output capability, duty and position feedback.

Service conditions

Stainless steel selection depends on composition, concentration, temperature and cleaning conditions, including factors such as chloride exposure. Match grades, cast or forged forms and wetted internals to the service.

Construction and description

Define fluid composition and continuous and start-stop operating conditions, then assess body, internals and seals as a combination. Particles, deposits and cleaning affect sealing surfaces and mechanisms; plan maintenance for the actual service.
