Principle of operation

The valve is actuated by solenoid. The direction of working medium is one-way to the gate. The backpressure (when outlet fitting pressure exceeds inlet pressure) or opposite direction of working medium is not allowed. These result in spontaneous opening of the valve.

The gate pressure drop is not required for operation.

т – nipple connection without matching installation kit; т1 – nipple connection with matching installation kit as per ГОСТ 5890, type 1; т2 – nipple connection with matching installation kit as per ГОСТ 5890, type 2; м – socket joint; ф – flanged connection without matching flanges; ф1 – flanged connection with matching flanges as per GOST 12821; ф2 – flanged connection with matching flanges as per GOST 12820 (only for PN up to 2,5

MPa);


Solenoid valves of special design:

- medium temperature up to 300˚С with metal sealing of seat; DN 50; PN 2,5MPa max.;

- two direction of operating medium flow, with operating pressure up to 1,0 MPa (at

backpressure applied), DN 3…10, with reinforced return spring;

- two direction of operating medium flow, with operating pressure up to 1,0 MPa (at

backpressure applied), DN 15…25, with cup-type seal between core and protection pipe

of solenoid;

- valves with pulse controlled solenoid; DN 3…50; PN 4,0 MPa max.;

- rubber seal seat;

- built-in position indicator;

- body with elbows;

- with pipe branches for welding as per GOST 16037-80, cutting С-17;

- Solenoid valves with pilot stage DN 65, 80, 100, 125, 150 for operating pressure

1,0…10,0 MPa;

- Solenoid valves with forced piston displacement DN 100 for operating pressure 0…1,0

MPa;
