Side Actuated Gate Valve

Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid.

Side actuated gate valve.

Gate valve general information gate valve operation description pneumatically actuated gate valves are opened and closed by applying air pressure to either side of a piston located in the air cylinder of an actuator housing. 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. They re designed to meet or exceed awwa standards and have for decades been recognized as the original and definitive standard. 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 are operated by a threaded stem which connects the actuator generally a hand wheel or motor to the stem of the gate. 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. Gate valves with rising vs non rising stem design.

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. The two main types of linear actuators are diaphragm and piston.
