Side Actuated Gate Valve

Gate valves with rising vs non rising stem design.

Side actuated gate valve.

Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid. Resilient wedge gate valves resilient wedge valves from clow valve company bring the latest technology and more than a century of engineering expertise to your water system. Rising stems are fixed to the gate and they rise and lower together as the valve is operated providing a visual indication of the valve position and making it possible to grease the stem. The gate faces can be parallel but are most commonly wedge shaped in order to be able to apply pressure on the sealing surface.

These types of valves include globe valves rising stem ball valves control valves and gate valves. The gate valve cycle time is controlled by air pressure entering into and exhausting out of the air cylinder simultaneously. A gate valve also known as a sluice valve is a valve that opens by lifting a barrier gate out of the path of the fluid gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. If the valve has a rising stem its position can be seen just by looking at the position of the stem.

The two main types of linear actuators are diaphragm and piston. They re designed to meet or exceed awwa standards and have for decades been recognized as the original and definitive standard.
