Product Introdution
Gate valves normally have flanged ends which are drilled according to pipeline compatible flange dimensional standards. Our Gate valves are typically constructed from cast iron, ductile iron or cast carbon steel.
Gate valves are characterised as having either a rising or a non-rising stem. Rising stems provide a visual indication of valve position because the stem is attached to the gate such that the gate and stem rise and lower together as the valve is operated. Non rising stem valves may have a pointer threaded onto the upper end of the stem to indicate valve position, since the gate travels up or down the stem on the threads without raising or lowering the stem. Non rising stems are used underground or where vertical space is limited
