HPEFV ADJUSTABLE HIGH PRESSURE SAFETY EXCESS FLOW VALVE

HPEFV ADJUSTABLE HIGH PRESSURE SAFETY EXCESS FLOW VALVE

Excess Flow Valves

ChemTec CTE

Flow enters the unit and makes a right angle to the outlet port across the nose of a magnetic piston. The piston is held in place by attraction to an adjusting screw magnet. A pressure differential is created by flow across the piston. When the differential is great enough, the piston slides to a seat at the outlet port. The flow rate at which the piston actuates can be changed externally by turning the adjusting screw, thereby changing the piston’s relationship with the flow stream.

In the auto reset model after actuation, the piston resets on a metal to metal seat that allows a controlled bleed. To reset the unit, pressure must be equalized on both sides of the piston. If the source is turned off, either upstream or downstream, the bleed will equalize the pressure and the valve will automatically reopen by magnetic repulsion from the fixed magnet located in the valve body.
