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.
Construction
Parts and materials
The gate valve 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. The flow is stopped when the diameter of the nominal bore of the pipeline is completely blocked, and adjusted when it is partially blocked.
