Beschreibung
The gate valve is designed for installation on the pipeline as a shut-off device and regulation of the working medium flow in water supply systems (except for drinking water supply systems) and chemical industry. The principle of operation of the gate valve is to move the gate (knife) perpendicular to the flow of medium. At full closing of the pipeline nominal bore diameter the flow is stopped, at partial closing the flow is regulated.
Explosion-proof electric actuators with explosion protection marking 1ExdIIBT4 multi-turn actuators of GZ-VA, VB, BB, VG, VD types with double-sided torque limiting coupling (type of connection to the valve - according to OST 26-07-763-73) are used for control of pipeline shut-off valves in chemical, oil, gas and power industries.
