Side Actuated Gate Valve

Gate valves with rising vs non rising stem design.

Side actuated gate valve.

Diaphragm actuators are made out of a round piece of rubber and squeezed around its edges between two side of a cylinder or chamber that allows air pressure to enter either side pushing the piece of rubber one direction or the other. 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. These types of valves include globe valves rising stem ball valves control valves and gate valves. The two main types of linear actuators are diaphragm and piston.

The gate faces can be parallel but are most commonly wedge shaped in order to be able to apply pressure on the sealing surface. The gate valve cycle time is controlled by air pressure entering into and exhausting out of the air cylinder simultaneously. If the valve has a rising stem its position can be seen just by looking at the position of the stem. 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.

They re designed to meet or exceed awwa standards and have for decades been recognized as the original and definitive standard. They are operated by a threaded stem which connects the actuator generally a hand wheel or motor to the stem of the gate.
