The Pneumatic Butterfly Valve Actuator is an automatic control device that relies on compressed air to drive the butterfly valve to open and close. It is widely used in various fluid pipeline systems.
Category
Pneumatic butterfly valve actuators are available in two types: single-acting and double-acting. The double-acting actuator controls both opening and closing through pneumatic power. In contrast, the single-acting actuator features a spring return function, allowing it to automatically close or open in the event of gas or power failure.
Working principle
The pneumatic butterfly valve uses compressed air as the power source to drive the valve stem, which controls the disc-shaped butterfly plate to rotate around its axis. The initial valve position is set according to the specific requirements. When the valve rotates 90° from its initial position, it completes one action (either from open to closed or from closed to open). The reverse rotation of 90° marks the completion of the opposite action (either from closed to open, or from open to closed).
Advantage
Efficient drive
The pneumatic Butterfly Valve Actuator uses an efficient pneumatic actuator, which can complete 90° opening and closing within 1~2 seconds, ensuring fast response, and is suitable for pipeline systems with high requirements for opening and closing speed.
Accurate flow control
When used with a valve positioner, the Pneumatic Butterfly Valve Actuator can accurately adjust the flow rate, and the position accuracy can reach ±2%. Suitable for automatic control systems that require fine adjustment.
Safe and reliable
Pneumatic Butterfly Valve Actuator provides two types: single-acting and double-acting. The single-acting type is equipped with a spring return function, which ensures that when the air source or power supply fails, the actuator can automatically close or open the valve, improving the reliability and safety of the system.
Convenient installation
The pneumatic Butterfly Valve Actuator has a compact structure and a small size. The standard interface can match various butterfly valves, and the installation time only takes 20~30 minutes.
