A514 Differential Pressure Switch

The A514 Differential Pressure Switch features highly sensitive pressure sensors on both sides that trigger the switch mechanism to control equipment like motor-driven valves. It's typically used to manage pressure differences between supply and return pipes in water and oil systems. For example, it can control a valve in the bypass near the pump; when the pressure difference exceeds the set value, the valve opens or closes to maintain normal system operation. Certifications: UL
