Ashcroft B424V-30 General Purpose Pressure Switch Overview
The Ashcroft B424V-30 is a reliable, field-proven general purpose pressure switch engineered for demanding HVAC, refrigeration, and industrial control applications. With a 0–30 PSI operating range and a single-pole double-throw (SPDT) switching action, this unit delivers precise, repeatable pressure-activated control in a compact, robust package.
Key Features
- Pressure range: 0–30 PSI for broad compatibility across low-pressure system monitoring and control
- SPDT (Single-Pole Double-Throw) switching action for versatile normally-open or normally-closed circuit configurations
- 1/4″ NPT process connection for easy installation into standard piping and manifolds
- Viton seal for superior chemical resistance and compatibility with a wide range of refrigerants, oils, and process media
- NEMA 4X watertight enclosure rated for indoor and outdoor use — protects against dust, dirt, rain, splashing water, and corrosion
- General purpose design suitable for HVAC systems, compressors, pumps, and process equipment
Why Choose the Ashcroft B424V-30?
Ashcroft is a globally recognized leader in pressure measurement and control instrumentation. The B424V-30 combines a chemically resistant Viton seal with a rugged NEMA 4X enclosure, making it an ideal choice for installations where moisture, corrosive atmospheres, or harsh environments are a concern. The SPDT output provides maximum wiring flexibility, allowing technicians to configure the switch for either normally-open or normally-closed operation without additional hardware.
