Dimensions
pneumatic valve
introduce
Pneumatic actuators are used to replace manual operation. They work by using compressed air as a power source, which drives a piston to rotate a crank arm 90 degrees, thus automatically opening and closing the valve.
Features
1. Low cost 2. Easy maintenance
3. High output power
electric valve
introduce
Electric valves use electrical energy to power an electric actuator, which in turn drives the valve to open, close, or regulate the flow of media in a pipeline. Electric valves are mostly used for regulating pipeline flow, typically installed at the outlet of air supply and refrigeration ducts. They can also be used in liquid pipelines, and are widely used in beverage bottling lines and wastewater treatment systems.
Features
1. Simple structure 2. Long service life 3. Suitable for almost all media
