AVK International A/S

Bizonvej 1, Skovby, 8464 Galten, Denmark

Needle valve PN10/16 for flow rate control and pressure reducing applications and regulation of water flow with clean water to 70°C.

AVK series 872 needle valves are designed for regulation or throttling of water at high flow rates and pressure in piping systems for water supply. The focus is on durability and reliabilty with the sturdy valve housing made of either stainless steel or ductile iron coated with fusion bonded epoxy. It regulates with high precision and the high quality materials guarantee long service life with easy maintenance access.

Variant 872/00-001
Connection: Flanged
Material: Ductile Iron
DN: DN80 - DN1600
PN: PN16
