HNBR O-Ring gaskets
4-way Reversing Valves are CE approved products according to 93-27-EC Directive
Optional: valve mounting CuFe2P tubes, with socket welding connections

Advantages

Cycle inversion needs no solenoid pilot valve and no slider movement, reducing risk of mechanical seizures
In comparison with the solenoid piloted valves, where the pressure differential pilots themovement of a slider which changes the direction of the refrigerant, the ball-valve design guarantees minimum pressure drop and very low risk of leakage and ensures quick changeover, even without any pressure differential
The ball is suspended by 4 Teflon seats, it is able to perfectly works even at maximum temperature or even in case of total absence of pressure in the system
The models offer a wide range of connection sizes and allows special configurations and capacity for specific applications on request
