CARRIER HK02ZA439 HK02ZA439 HIGH PRESSURE SWITCH HIGH PRESSURE SWITCH

PRESSURE SWT 426#OPN 320#CLS

Four terminal solenoid valve designed to activate switches or set points at predetermined pressures. The unique design of this valve eliminates the need to set the control system pressure to utilize it as an on-off switch. A unique safety feature allows the user to activate and deactivate solenoid easily with a switch from separate power supply source in case of high pressure application. This eliminates the need for manually resetting the system pressure for on-off operation.

The Carrier HK02ZA439 is a pressure switch. The function of the pressure switch is to sense differential in pressure across the switch resulting from an external force, e.g., pump or flow. Applications for this pressure switch are pumps and advanced flow control systems.
