AVK CONTROL VALVE, PRESSURE SUSTAINING/RELIEF, PN10/16

Reduced bore, AISI 316 pipes and fittings

Industrial Netherlands building

Contact

AVK Industrial Nederland BV

Schorsweg 1 8171 ME Vaassen Netherlands

Pressure sustaining/relief control valve, reduced bore, for water and neutral liquids to max. 70° C

AVK series 859 diaphragm actuated pressure sustaining control valves (PSV) automatically secure a minimum upstream pressure by reducing the flow if the upstream pressure drops below the setpoint.

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.

Variant 859/001X-001
Connection: Flanged
Material: Ductile iron
DN: DN65 - DN300
PN: PN 10/16

Features

Main control valve

  • Lifted seat to avoid damage due to cavitation
  • Geometry of regulating plug provides high ratio of travel against 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
