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

A heating jacket uses an external heating medium to help maintain body-region temperature where solidification or viscosity changes matter. Review process and jacket conditions separately, including heating connections, drainage, heated coverage, shutdown emptying and restart.
