Product overview

Vacuum Isolation Globe Valve

Service conditions

A globe valve opens or closes its flow path through linear movement of a disc relative to the seat. Disc travel changes the opening at the seat. Throttling service requires suitable disc geometry and an assessment of flow demand, differential pressure and the pressure loss caused by changes in flow direction.

Configuration

Select the manual operator or actuator to suit the valve torque or thrust requirements and site operating conditions. Provide access and clearance for manual operation. For frequent cycling or remote operation, assess actuator output, duty cycle and valve-position feedback.

Service conditions

Vacuum service requires attention to leak tightness, material outgassing, sealing arrangements and connection cleanliness. Define the operating pressure range, gas or vapour to be evacuated and bake-out conditions, and check compatibility with vacuum flanges, pumps and instruments.
