VG7441RT+823E01 Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7441RT+823E01 is an actuated valve assembly combining a 1-1/2 inch 2-way normally closed globe valve with an MP82 spring return pneumatic actuator and V-9502 positioner. Constructed with a cast bronze body and brass trim, it provides reliable flow control for hot water, chilled water, glycol solutions up to 50%, or steam in commercial HVAC and building automation systems.

Features

• Features a 2-way, normally closed configuration with push-down-to-open valve action.
• Utilizes an MP82 spring return pneumatic actuator with a 9 to 13 psi spring range.
• Employs an equal percentage flow characteristic for precise and stable fluid modulation.
• Built with a rugged bronze body and standard threaded stem for durable operation.

Specifications

• Pipe Size: 1-1/2 inch NPT
• Flow Capacity: 28.9 Cv
• Safe Working Pressure: 400 psi maximum
• Close Off Pressure: 79 psi
• Temperature Range: 35 to 284 degrees F
• Leakage Class: ANSI Class IV (0.01% of maximum flow)

Applications

• Commercial HVAC hydronic heating and cooling control.
• Variable flow chilled water and hot water distribution systems.
• Fan coil unit (FCU) and air handling unit (AHU) coil modulation.
• Integration into building automation and direct digital control systems.
