DN 150 Weflo Non-Rising Shaft Gate Valve Features
Weflo Non-Rising Stem Gate Valve is UL and FM approved. Weflo Non-Rising Stem Gate Valve is one of the valves used as regional control valve. Non-Rising Stem Gate Valves They are generally produced for control and cutting purposes in fire pipelines that need to be buried underground in outdoor areas where the possibility of freezing is high.
Since the open or closed positions of the valves used in fire systems must be visible and monitorable, it is recommended to use a post indicator instead of a handwheel in fixed non-rising stem valves. Non-rising stem slide valves are suitable for use in indoor and outdoor environments.
The disadvantages of non-rising stem gate valves compared to other cut-off and control valves are their large volume and their uneconomical price. As for their advantages; Pressure losses are much lower compared to other control and cut-off valves. In addition, the valve being outside allows the structure to be protected against fire even during maintenance and repair.
They are used in pipelines buried underground in outdoor areas against the risk of fire installations freezing outside.
