AVK CONTROL VALVE, PRESSURE REDUCING, KS/PN10

Reduced bore, SS 316 trim, EKV70 rubber, 300µm blue EP, press. gauges P1/P2

Control valve pressure reducing (PRV) for drinking water or other 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.

특징

Main control valve

  • Lifted seat to avoid damage due to cavitation
  • 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 except main diaphragm with multiple approvals (EN 681-1, KTW, W270, ACS, WRAS), main diaphragm use EKV rubber.
  • Lifting ribs are available from DN150
  • KC and CP approved

Pilot system

  • Modular and compact design for easy application change
  • Integral Valve, mainly used for isolating the control chamber, fixing position of main valve, in case of servicing the pilot circuit. The integral Valve, can also be used, adjusting main valve reaction time
  • Main components made of stainless steel AISI 316

             o Distribution block:

                - Connecting main control valve to pilot system

                - Control orifice

             o Filter:

                - High capacity, easy to flush with possibility of back flushing

                - Mesh 100, high performance wire screen type

             o Hydraulic control block:

                - Includes balance pilot, providing a more stable pressure setpoint

                - Can be set up for different applications using single-function or multi-function modules
