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.
Features:
- MTTF of 5,000,000 cycles
- Controlled pump down to match process
- Aluminium bodies
- Fast acting valves in the event of power failure
- Supplied with 5 mm, 6 mm and 7 mm interchangeable orifices
