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

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 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

• 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
