Edwards Soft Start Isolation Valves

Soft-start, pneumatically operated, in-line valves with interchangeable orifices for the controlled pump-down of processes where turbulent flow can cause problems with particulate contamination. Slave and master valve combination allows slow initial pumping to minimise disturbance. Both slave and master valves require separate pneumatic connections.
