The globe valves refer to the stop valves of two-position action.

They are only used for opening or blocking of pipelines by means of reciprocative movement of the shut-off device.

The globe valve control is carried out with the help of:
● a lever or handwheel (М);
● a built-in electric actuator (E);
● a universal ball joint (G);
● a cylindrical reduction gear unit (Cy);
● a cone reduction gear unit (Cn).

The valve configuration is adapted to application of electric
actuators manufactured by the following companies:
● Э – Barnaul Boiler Plant, LLC; CHZEM, Chekhov;
● ЭГ – GZ Elektroprivod, Moscow;
● ЭЧ – ABS ZEIM Automation, OJSC, Cheboksary;
● ЭН – BETRO-Tech, Berdsk;
● ЭМ – Tulaelektroprivod, Tula;
● ЭК – ZPA Ресky, Czechia;
● ЭД – АUMA, Germany;
● other manufacturers with standard connection units.

The allowed values of operating pressures and temperatures for the fittings may differ from those ones given in the table with technical specifications and are chosen in accordance with GOST 356-80, provided that they shall not exceed the limits prescribed by the respective State Supervision Rules and Standards for these materials and operation conditions.

According to GOST 356-80, the items designed for the ultimate pressure allow their application on operating parameters within the following range:
● at PN 10 MPa – from 10 MPa, 200 ºС to 3,6 MPa, 455 ºС;
● at PN 25 MPa – from 25 MPa, 200 ºС to 9 MPa, 455 ºС;
● at PN 6,3 MPa – from 6,3 MPa, 200 ºС to 2,3 MPa, 455 ºС.
