- Applicable medium: Suitable for liquids that contain water, ethylene glycol, oil or other liquids that are not classified as dangerous or corrosive, and air. - High quality: Brass shell; maximum operating pressure 1.5 MPa; protection class IP54; the service life of the contactors up to 100,000 times. - Working principle: Flow control valve is adjustable with a stable repeat action point. When the flow rate exceeds the set value, the fluid drives the rotor and micro switch. The SPDT contact can connect a circuit and disconnect other circuits. - Adjusted paddle: The water flow switch is typically used in places where locking or breaking protection is required. The number of paddles and the length of the paddle can be adjusted to suit different pipe diameters and flow rates. - Use scenarios: - Industrial cooling or heating loops: monitors liquid or air flow and triggers circuit changes to protect pumps and prevent overrun or dry running. - Chemical processing lines: integrates with control systems to manage flow of water, glycol, or oil while maintaining safety through adjustable paddle configurations. - Pneumatic and hydraulic systems: provides interlock and safety shutoff by switching circuits when flow conditions exceed preset limits.
