VG7443PT+822E00 Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7443PT+822E00 is a 2-way, 1-1/4 inch cast bronze globe control valve assembly equipped with an MP82 spring return pneumatic actuator. Part of the VG7000 Series, this assembly is designed to provide precise flow control of hot water, chilled water, or saturated steam in commercial HVAC and building automation systems. It operates in a normally closed configuration (push-down-to-open) and features a durable design engineered for long service life.

Features

• High-quality cast bronze body construction with robust stainless steel trim for extended wear resistance
• Interoperable MP82 pneumatic actuator with a 25 sq. in. effective diaphragm area and 1/2-inch stroke
• Spring return mechanism providing a reliable fail-safe mode (normally closed)
• Maintenance-free design with self-adjusting Ethylene Propylene Rubber (EPR) ring pack U-cup packing
• Standard threaded stem and ANSI Class 250 static pressure rating for structural stability
