Ashcroft B424V 60 H2O Pressure Switch 20 Psi 1/4 Nptf

Product Description

The ASHCROFT B424V 60 H2O is a watertight single setpoint pressure switch designed for industrial and commercial process control applications. It features a 316 stainless steel wetted material construction and an aluminum housing rated for environments where moisture ingress is a concern. The switch carries a maximum pressure setting of 20 psi and operates across a wide voltage range including 125, 250, and 480 volts AC as well as 30, 125, and 250 volts DC. The SPDT contact form supports flexible wiring configurations. A licensed electrician or instrumentation technician is the typical installer for this class of device.

This pressure switch is suited for use with air, food-grade processes, oil, and water systems in both commercial and light industrial settings. Its setpoint adjustability allows field calibration to match specific system pressure thresholds. The operating temperature range of -20 degrees F to 150 degrees F makes it appropriate for a broad range of indoor and outdoor installations. The 1/4 inch NPTF male thread connection is a common fitting size across pneumatic and hydraulic process lines.
