How it works
Multi-turn handwheel
Rising-stem wedge 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.
Construction
Parts and materials
The wedge gate valve is designed for installation on pipelines as a shut-off device in water supply systems and chemical industry.
The wedge connected to the spindle is lowered or raised depending on the direction of rotation of the hand wheel, closing or opening the passage cross-section of the gate valve body.
Special features: two rows of holes, which allows the gate valve to be installed using appropriate fasteners on pipelines with a working medium pressure of 10 or 16 bar; 250 µm thick epoxy powder coating on the inside and outside of the body.
Supports the gate valve by means of an epoxy powder coating.
