Altecnic Series 519 Ecopas Full Flow Differential Bypass Valve - 3/4" Female x Male Union - 519500

Description

The Series 519 differential bypass valve uses a stainless steel compression spring to exert a pre-determined force onto the disc. The force is adjustable by turning the control knob to set the required differential pressure between 1 to 6 m head which corresponds to 10 to 60 kPa. The setting is then locked using the locking screw on the side of the control knob to prevent unauthorised adjustment.
