VG7241PT+3008DP Johnson Controls Valve / Actuator

Overview

The Johnson Controls P72AA-27C is a Double-Pole Single-Throw (DPST) electromechanical pressure control designed primarily for high-pressure applications, such as condenser fan cycling control, head-pressure control, and high-pressure cut-out in commercial refrigeration and air conditioning systems. It features an Open Low switch action that responds directly to system pressure drops.

Features

• All-steel case and cover provide rugged, long-lasting protection for internal components.
• Sight-Set calibrated pressure adjustment displays a visible scale for easy adjustments without removing the cover.
• DPST switch with load-carrying contacts allows for the direct control of high-horsepower motors.
• Equipped with a 36-inch capillary with a 1/4-inch flare nut for flexible installation.
