AVK PLUNGER CONTROL VALVE, STAINLESS STEEL, PN25

SS internals, bronze piston, SS guides, A4/A2 bolts, Rotork gearbox, modulating, uncoated

Plunger control valve for flow rate control and pressure reducing applications. For water and other neutral and hydrocarbon-free media to max. 70°C.

AVK series 870 are designed as plunger control valves for inline applications. Unlike butterfly- or gate valves, that should only be in either fully open or fully closed position, plunger valves are designed to operate in between and perform control functions in water supply systems.

The design consists of a single-piece body made of cast stainless steel, 1.4308 (CF8). Internal components in contact with water are made of either stainless steel or bronze; materials that guarantee a good anti-corrosion performance and a long service life.

특징

  • One-piece body construction
  • T-shape main seal located in safety flow area ensuring minimal wear and long service life
  • Maintenance access is conveniently provided by the downstream retaining ring and the upstream cover being attached with screws
  • Low operating torque due to pressure balance in chamber inside
  • Gearbox suitable for modulating operation
  • Low head loss coefficient in fully open position due to optimized internal body shape
  • Double O-ring sealed drive shaft with all other shafts and bearings protected against corrosion with O-ring combinations
  • 4 guide rails ensure no vibration during operation and accurate alignment throughout full valve stroke
  • Body and internal parts in stainless steel. Guide rails integrated in the body
