Frequently Ask Questions
A diaphragm actuator is a pneumatic device that uses air pressure to move a flexible diaphragm and operate a valve. It converts air energy into linear motion for precise control.
Alis Valves is a trusted manufacturer offering high-quality and reliable diaphragm actuators. They provide durable solutions with good support and customization.
It works by applying air pressure on a diaphragm which moves against a spring. This movement controls the valve opening or closing.
Yes, they can be integrated with positioners and control systems. This allows accurate and automatic valve operation.
They are used for controlling flow, pressure, and temperature in control valves. Common in industries like chemical, power, water, and oil & gas.
Choose based on valve size, air pressure, fail-safe requirement, and application conditions. Also consider stroke length, thrust, and accessories like positioners.
Diaphragm actuators offer precise control and are used in control valves. Piston actuators provide higher force and are used in heavy-duty applications.
Fail-safe means the actuator moves to a safe position (open or close) when air supply fails. This is achieved using a spring return mechanism.
