Premaflex Pinch Valve
By pressing additional compressed air or water into the Premaflex Pinch Valve casing, a special, highly elastic collar is compressed. This will close the collar and will absolutely block the stream of material, even if it contains pieces of solid material. Due to the highly elastic collar, the valve's functionality will be maintained even with frequent switching. After switching off the control medium, the collar will automatically reopen on account of its adaptive quality. Resistance to chemicals (waste water, caustic and acid liquids), resistant to fire and temperatures from -20°C to +120°C (depending on the gasket material). As an alternative to the valves operated by means of additional compressed air, we can also offer valves that are opened and closed manually.
