The body of vacuum valve 25M URS is made of welded construction and consists of a shell, seat, side and bottom spigots. The 25M URS valve is connected to the vacuum system by studs.
The smooth part of the stem serves as a visual indication of the "open" or "closed" position of the valve. The cover is designed to protect the valve from accidental opening and also serves as an additional protection against ingress of atmospheric precipitation, sand, dust into the internal cavity of the valve.
The valve is opened by turning the handwheel anti-clockwise. Closing of the valve occurs when turning the handwheel clockwise.
