AVK Series 870 Plunger Valve
AVK series 870 is a plunger control valve which in some areas also is called a needle
valve in the industry for inline applications of regulation. Unlike butterfly or gate valves
assuming only fully open or shut off functions, plunger valves are designed to operate
in between and fulfil control functions (pressure and flow) in water supply systems.
The design holds a single-piece body of fusion bonded epoxy coated ductile iron
(above DN150) or stainless steel (up to DN150 and DN400, DN600). All internal
components are made of either stainless steel or bronze materials that guarantee
good anti-corrosion properties and a long lifetime.
