They are only used for turning on and off the pipeline.
The usage of the gate valves as control devices is not allowed.
When using gate valves in the pipelines, wherein the heating-up mode at the closed gate and water-filled internal cavity are provided, they shall be equipped with a discharge device. Such device may be produced in form of a pipe connecting the internal cavity of the gate with the pipeline on the side of the medium supply with a valve DN20 installed thereon, or in form of a through hole with the diameter of 5 mm in the plate on the side of the medium supply.
The valve configuration is adapted to application of electric actuators manufactured by the following companies:
Э – Barnaul Boiler Plant, LLC; CHZEM;
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.
