APV has specially developed the DELTA UF pressure relief valves to protect installations against excess pressure.
If the set pressure is exceeded, the valve opens; if the pressure sinks below the set value (up to a maximum of 20%), the valve closes.
- Optimal cleaning possibilities. Free draining ensures trapped product or CIP residues.
- No stroke limitation by seat lift actuator and so the full diameter of the opening is available during cleaning.
- Particularly easy to service - only four screws to be loosened and the valve insert can be lifted out upwards.
All valves can, in addition, be provided with a seal lifter, e.g. to relieve pressure during cleaning operations.
There is provision for mounting feedback signal proximity switches in the actuator yoke. All product-contact parts are manufactured from AISI 316 series stainless steel.
The valves can be supplied in nominal diameters of DN 25 - 100 and 1" - 4".
