Pressure reducing control valve, full bore, for water and neutral liquids to max. 70° C
AVK series 859 diaphragm actuated pressure reducing control valves (PRV) automatically reduces a higher inlet pressure to a lower constant outlet pressure, regardless of flow demand or changes in inlet pressure.
A replaceable spring inside the pilot makes it possible to operate in different pressure ranges and still keep the high precision. Setting and adjustment on a control knob on the pilot.

Features
Main control valve
- Lifted seat to avoid damage due to cavitation
- High Kv value at fully open position
- Geometry of regulating plug provides high ratio of travel Kv, resulting in optimal control performance
- Non-symmetric axial position of rubber diaphragm results in less stretch/stress near closed position
- All non-coated internals made of stainless steel AISI 316
- Body and bonnet of ductile iron with fusion bonded epoxy, 300micron, GSK approved, RAL 5017, according to DIN 3476 and WRAS-DVGW/W270/UBA.
- All rubber components with multiple approvals (EN 681-1, KTW, W270, ACS, WRAS)
Pilot system
- Modular and compact design for easy application change
- Main components made of stainless steel AISI 316:
- Distribution block:
- Connecting main control valve to pilot system
- Easy adjustment of regulating speed
- Control orifice - Filter:
- High capacity, easy to flush with possibility of back flushing
- Mesh 100, high performance wire screen type - Hydraulic control block:
- Includes balanced pilot valve providing more stable pressure set
- Can be set up for different applications using single-function or multi-function modules
