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.
A V-shaped opening provides a defined change in flow area as the ball rotates. Actual control behavior depends on the opening geometry, flow coefficient, available differential pressure and actuator positioning. Review the operating flow range and erosion at the opening.
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.
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.
