How it works
Knife gate
The number that matters
Nominal pressure
16bar
The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.

Gate valve GVKR-2W-Fb-OST stainless steel, interflanged with OST-flange and bare stem under electric actuator is designed to be installed on the pipeline as a shut-off device and regulate the flow of medium in water supply systems (except 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. In case of complete closing of the pipeline nominal bore diameter the flow is stopped, in case of partial closing the flow is regulated.
