Ashcroft 93264 Pressure Switch 500 Psi 1/4 Inch Nptf Spdt

Product Description

The ASHCROFT 93264 is a watertight single setpoint pressure switch designed for industrial and commercial control applications requiring reliable pressure-activated switching. It features a 1/4 inch NPTF male threaded process connection and an SPDT contact form, making it compatible with a wide range of control circuit configurations. The switch supports a maximum pressure setting of 500 psi and operates across a broad voltage range including 125, 250, and 480 volts AC and 30, 125, and 250 volts DC. The wetted components are 316 stainless steel, and the housing is aluminum construction. Licensed HVAC technicians, plumbers, and industrial controls specialists are the typical installers.

The 93264 is suited for use in air, food-grade, oil, and water systems where a watertight, adjustable single setpoint switch is required. Its adjustable setpoint and wide media compatibility make it appropriate for both process control and mechanical systems monitoring in residential, commercial, and light industrial environments. The operating temperature range of -20 degrees F to 150 degrees F covers most typical HVAC, plumbing, and fluid-handling applications.
