The direct-acting solenoid valves 1901R-KDN, 1901R-KDV are characterized by the absence of a diaphragm or piston booster, and the principle of operation when the valve is opened is to use only coil energy. Direct-acting valves have a simple design and a minimal number of moving elements, which leads to increased reliability and average operating time to failure.
The solenoid valve can be used as a relief valve in reciprocating compressors to control the air flow. The maximum operating pressure of the valve is 25 bar (2.5 MPa), and the minimum is 0 bar. In addition to air, the valve is used for various media: water, steam, propylene glycol. Depending on the modification, it has a 2.5 mm or 5 mm bore.
The valves are equipped with electromagnetic coils = 24 V or ~220 V from the famous Italian manufacturer AMISCO s.p.a.
