Ashcroft B424V Vac Pressure Switch 250 Psi 1/4 in

Product Description

The ASHCROFT B424V VAC is a watertight single setpoint pressure switch designed for use in industrial and commercial fluid systems where reliable pressure monitoring and control are required. The switch features a 1/4 inch NPT process connection and a maximum pressure setting of 250 psi. Its watertight construction makes it suitable for installations in wet or wash-down environments where moisture exposure is a concern. Licensed technicians and instrumentation professionals install this type of device to trigger alarms, shut down equipment, or activate auxiliary circuits when system pressure reaches a defined setpoint.

This pressure switch is appropriate for use in HVAC hydronic systems, plumbing, compressed air, and light industrial fluid control applications. The single setpoint design simplifies wiring and commissioning in scenarios where one trip point is sufficient. Its compact form factor allows installation in tight panel or pipe configurations where space is limited.

Key Features

• Watertight construction suitable for wet and wash-down environments
• Single setpoint design for straightforward pressure trip control
• Maximum pressure setting of 250 psi
• 1/4 inch thread process connection for standard pipe fittings
• Compact form factor compatible with space-constrained installations

Compatibility

Designed as an OEM-style replacement or new-installation pressure switch for systems utilizing a 1/4 inch threaded process connection with pressure ranges up to 250 psi.

Installation Notes

Installation should be performed by a qualified technician or instrumentation professional. De-energize and depressurize the system fully before removing or installing this switch. Verify thread type and pipe material compatibility before applying sealant or thread tape to the process connection. Follow applicable local codes and manufacturer wiring diagrams when connecting switch output circuits.
