AVK PLUNGER CONTROL VALVE, STAINLESS STEEL, PN10/16
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.
