Butterfly valve with actuator electric valve - An electrically actuated butterfly valve is a quarter-turn valve controlled by an electric motor. It offers fast and precise flow regulation, remote operation, and versatility for various applications.
The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator. Another valve actuator is visible in the background, with windows to indicate the valve position. A valve actuator is the mechanism for opening and closing a valve. Manually ...
The inside of an extremely large butterfly valve Duplex ball valve Three check valves in corrosion-resistant Hastelloy Stainless steel gate valve. Valves can be categorized into the following types, based on their operating mechanism: Ball valve, for on–off control without pressure drop. Ideal for quick shut-off, since a 90° turn completely ...
Pneumatic valve: Actuated using a compressible medium like air, hydrocarbon, or nitrogen, with a spring diaphragm, piston cylinder or piston-spring type actuator; Hydraulic valve: Actuated by a non-compressible medium such as water or oil; Electric valve: Actuated by an electric motor; A wide variety of valve types and control operation exist.
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 are electrically powered; others may be powered pneumatically or hydraulically , or use energy stored in springs .
Swirl flap principle in a four-valve engine. A swirl flap is a small butterfly valve fitted to four-stroke internal combustion engines with at least two intake valves.It is installed inside or just before one of a cylinder's two intake ports, allowing to throttle its intake port's air flow, causing a swirl in the other intake port not fitted with a swirl flap.
