In this guide, we'll discuss the two primary types of valve operation, types of valve actuators, important valve actuator functions, valve sizing information, and the key considerations in selecting the right MTD valve actuator.
Valve actuators are a type of control valve, and there are many options available to meet plant-wide and individual automation requirements. While simple in concept, consisting of a box with an input, output, and a mechanism to operate a valve, there are actually quite a few considerations in choosing the right valve actuator. And because the valve actuator plays a more significant role in a valve’s overall performance in the control loop, it’s a decision that engineers shouldn't take lightly.
Rotary (Quarter-Turn) Operation – This includes plug valves, ball valves, and butterfly valves. Quarter-turn dampers would also fall into this category. These types of valves are generally easier to fit with the appropriate actuator as the operation is relatively simple, requiring a 90-degree rotation at the appropriate torque.
Check the datasheet or catalog specifications for the torque output. Select a rotary actuator with enough muscle to move the load from resting to the desired speed. Typical torque units are expressed in pound-inches or Newton-meters. Remember, there will always be losses due to friction in the actuator.
Now that we’ve covered the basic types of valves and valve actuators, as well as the main functions valve actuators must perform, there are a few important considerations to weigh when selecting the appropriate actuator for your application. There are a variety of factors to consider, ranging from usage factors, to sizing, supply pressure requirements, safety and reliability, cost considerations, and more.

Compatibility
Electric closed valve is an electric one-way valve. When the closed valve is not powered, it is pressed by a strong spring and will not open due to the reverse air flow. Effectively guarantee the tightness of the corresponding space.
