½" Polypropylene Pressure Relief / Loading Valve with Plain Metric Union Ends 

• 750L/Hr Capacity
• Connection : 20mm Plain Union Ends
• Polypropylene Material
• Diaphragm Options: EPDM, FPM or PTFE
• Functions: Pressure Relief or Pressure Loadin g

A clear benefit of the valve design is their dual range capability - the same valve can be used in pressure relief or in pressure loading (sustaining) mode merely by selecting the relevant inlet port.

The body of the valve is ½" and the valve is commonly referred to as ½", but the union ends are metri c and designed for connection to polypropylene pipe that has an outer diameter of 20mm

OPERATING PRESSURE RANGES
• Pressure Relief Range: 1 - 10 BARG
• Pressure Loading Range: 0.5 - 3 BARG

APPLICATIONS
Pressure relief of dosing lines.
Pressure sustaining (loading) for dosing pumps.
Flow checking (where supply pressure is higher than pumped discharge pressure).
Anti-syphoning.
Combination back pressure & check valve.
Backpressure valving.
Pump re-cycle bypass relief.
Thermal expansion relief.
