Ashcroft LPDN4GGV25 30 Dual Setpoint Pressure Switch

Product Description

The ASHCROFT LPDN4GGV25 30 is a watertight dual setpoint pressure switch designed for industrial and commercial pressure monitoring applications. It allows two independent switching points to be set within a single unit, reducing the need for multiple switches on a system. Rated to a maximum pressure setting of 500 psi, it connects via a 1/4 inch threaded port. The watertight enclosure protects internal contacts from moisture, dust, and contaminants common in demanding service environments. HVAC technicians, plumbers, and industrial service professionals install this type of switch where reliable pressure-triggered electrical switching is required.

This pressure switch is suited for use in commercial HVAC systems, hydronic piping, compressed air systems, and general industrial fluid or gas pressure monitoring. The dual setpoint design makes it practical in applications where both a high-pressure cutout and a low-pressure alarm or control signal are needed from one device. Its watertight construction makes it appropriate for installations exposed to wash-down conditions or outdoor environments.

Key Features

• Dual setpoint design provides two independent switching thresholds in a single unit
• Maximum pressure setting of 500 psi suitable for a range of fluid and gas system applications
• 1/4 inch threaded process connection for straightforward installation on standard fittings
• Watertight enclosure protects against moisture and contaminants in harsh environments
• Compact form factor simplifies installation in tight panel or piping spaces

Compatibility

Designed as an OEM-style or direct replacement dual setpoint pressure switch for commercial and industrial systems requiring a 1/4 inch threaded connection and a maximum rated pressure of 500 psi.

Installation Notes

Installation should be performed by a licensed technician familiar with the pressure system being serviced. Depressurize and isolate the system before removing any existing switch or making new connections. Ensure thread sealant compatible with the process media is applied to the threaded port connection. Verify that electrical connections comply with applicable NEC requirements and that the circuit is de-energized before wiring the switch.
