Often made out of cast iron, butterfly valve's name is based from the functionality of its disc. There are a few different types of butterfly valves, however, they fall into two basic types - Lug and Wafer valves. More About Butterfly Valves. Butterfly valves are classified as "quarter-turn" valves.
Rotary valve. Rotary valves constitute a derivation of the general butterfly valves and are used mainly in powder processing industries. Instead of being flat, the butterfly is equipped with pockets. When closed, it acts exactly like a butterfly valve and is tight.
Butterfly Valve Types – Wafer, Lug, Double Offset and Triple Offset Types A Butterfly valve is a quarter-turn rotary motion valve, that is used to stop, regulate, and start the flow. Butterfly valves are a quick open type.
A rotary actuator is an actuator that produces a rotary motion or torque.. The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators though are electrically powered.
Type 8805 consists of a 90°swivel fitting (ball or butterfly valve) and a pneumatic rotary actuator. The rotary actuator is available as single or double-acting actuator. Type 8805 can be complemented by a positioner (8792), a pilot valve (6519) or several kinds of position feedback (1061).

Rotary movement valves, often called quarter-turn valves, include ball valves and butterfly valves. Regardless of the type of rotary movement valve, the obturator rotates about an axis perpendicular to the direction of flow. Fluid may flow through the obturator, as is the case with ball valves, or around it, as with butterfly valves.
Jun 22, 2019· Rotary Motion. Rotary valves have a closure member that moves with a rotary motion to modify the rate of flow through the valve. Like linear motion valves, rotary motion valves are generally named for the shape of their closure member. Common rotary motion valves include ball, butterfly and plug valves. Ball Valve
