Anthony Whittam
Network Water Specialist
Needle valve PN10/16 for flow rate control and pressure reducing applications and regulation of water flow with clean water to 70°C. Face to face DN 80: EN558 ser. 48, DN 100-1000: EN558 ser. 15
AVK series 872 needle valves are designed for throttling and control of pressure and flow at high flow rates and high differential pressures. The focus is on durability and reliability with the sturdy valve housing made of either stainless steel or ductile iron coated with fusion bonded epoxy. It controls with high precision and the high quality materials guarantee long service life with easy maintenance access.
