How it works
Multi-turn handwheel
Knife gate
The number that matters
Nominal pressure
10bar
The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.

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. In case of complete closing of the pipeline nominal bore diameter the flow is stopped, in case of partial closing the flow is regulated.
