VG7241ST+823C01 Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7241ST+823C01 is a 2-way, 2-inch pneumatic globe control valve assembly from the VG7000 Series. It combines a cast bronze valve body with an MP82 Series pneumatic actuator to regulate flow in commercial heating, ventilating, and air conditioning systems. Housed with a spring-return mechanism, the valve features a normally open fail-safe design (push-down-to-close) and operates within a 3 to 7 psi spring range.
