product presentation

Main applications :
Direct actuating of pumps of the water supply for sinks and showers in recreational vehicles (Caravans, motorhomes). It starts the operation of the pump when the valve is open and when the pressure drops in the circuit.

Fluid: Water
Pressure port connection: Plastic spouts, with barbed end for flexible reinforced tubing with an internal diameter of 10 mm.

Membrane: Silicone, thickness 1mm
Check valve: PA66 with silicone gasket and stainless steel spring Housing: PA66 compatible with drinking water.

Contact: SPNC opening by pressure rise
Electrical rating:
In alternating current: 16 (4)A 125 / 250VAC; 1/2HP 125VAC; 3/4HP 250VAC (Available up to 22 (8)A 250VAC, 2HP 250VAC) Direct current: 16 (4)A 12V
Electrical connection: 6.35 × 0.8mm quick connect terminals
Bursting pressure: > 4.5bar (0.45Mpa, 65PSI)
Ambient temperature limits: water: 0 to 85°C (32 to 185°F)
Mounting: 2 legs for mounting on a board surface with 2 screws with 40 mm distance
Operation: The non-return valve maintains the pressure in the water circuit when the submersible pump is stopped.

Caution: This device does not protect the pump against dry running Maximum calibration value: 1.1 bar (0.11 Mpa, 16 PSI)
