Side Actuated Gate Valve

If the valve has a rising stem its position can be seen just by looking at the position of the stem.

Side actuated gate valve.

They are operated by a threaded stem which connects the actuator generally a hand wheel or motor to the stem of the gate. The gate valve cycle time is controlled by air pressure entering into and exhausting out of the air cylinder simultaneously. Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid. 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.

Gate valves with rising vs non rising stem design. They re designed to meet or exceed awwa standards and have for decades been recognized as the original and definitive standard. 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. These types of valves include globe valves rising stem ball valves control valves and gate valves.
