Maintains a constant downstream pressure regardless of upstream pressure or flow rate fluctuations. The set point of reduced pressure is adjustable by a 2-way or 3-way plastic pilot valve. A spring-loaded diaphragm inside the pilot reacts according to the downstream pressure changes. The pressure fluctuations are compensated by gradual opening and closing of the valve. Includes Plastic Tubing & Fittings and 3 way valve. Working Pressure Range: 0.4 - 10 Bar [6 - 150 PSI]Flow Rate Range: 5 - 220 m3/h [22 - 970 gpm] KV 40 - 607
