●Description: Rising Stem Gate Valves are products which prevent
water flow and leakage when fully closed. When the valve is fully opened, it
does not have any affect which disturbs water flow. Sealing is achieved by
metal rings on the body and on the wedge. When the rings match with each other,
they provide sealing. The wedge moves up and down by turning the revolving stem
provided with a functional thread, enabling opening and closing of the valve.
With its rising feature, the user can detect from long distances whether the
valve is open or closed and act immediately on the situation. Furthermore, the
optional protection tube that is located at the top of the valve acts as a
protection to the rising stem which prevents obstacles from contacting to the
stem, and indicates whether the valve is fully opened or not. On the stem,
accessories such as actuator, extension spindle, gearbox, chain wheel etc. can
be assembled.
