Johnson Controls VG7243CT+7150G 1/2" NPT Two-Way Normally Open Stainless Steel Globe Control Valve Assembly 0.73 Cv

The Johnson Controls VG7243CT+7150G is a factory-assembled two-way globe control valve from the VG7000 Series Stainless Steel Trim line, paired with the VA-7150-1001 Non-Spring-Return Electric Actuator. Designed for precise fluid regulation in commercial and industrial HVAC systems, this normally open valve assembly delivers reliable on/off and floating control of hot water, chilled water, 50/50 glycol solutions, and steam.

Key Features:

• Valve Size: 1/2 inch NPT threaded end connections
• Flow Coefficient: 0.73 Cv with equal percentage flow characteristic
• Fail Position: Normally Open (push-down-to-close configuration)
• Trim Material: Stainless steel stem and seat for corrosion resistance and durability
• Close-Off Pressure: 239 psig maximum
• Max Static Pressure: 400 psig (up to 150°F), rated to ANSI Class 250 / ASME B16.15
• Fluid Temperature Range: 35°F to 338°F (2°C to 170°C) for water; 100 psig saturated steam
• Actuator Type: VA-7150-1001, Non-Spring-Return Electric, direct coupled — no linkage required
• Actuator Control: 24 VAC Three-Wire On/Off Floating Control, 50/60 Hz, 2.7 VA nominal
• Actuator Force: 90 lb (400 N) minimum for tight closeoff
• Actuator Ambient Temperature: 0°F to 140°F (-18°C to 60°C)
• Magnetic Clutch: Protects actuator gearing and ensures consistent tight closeoff
• Packing: Spring-loaded PTFE and elastomer V-rings for long service life
• Leakage: 0.01% of maximum flow per ANSI/FCI 70-2, Class 4
• Enclosure: NEMA 2 / IP42
• Electrical Connection: Screw terminals, 16 AWG maximum
• Assembly: Available factory or field assembled

This valve assembly is part of the Johnson Controls VG7000 Series, which is compatible with 1/2 through 2 inch valve bodies. The direct-coupled VA-7150 actuator mounts without external linkage, simplifying installation and reducing maintenance requirements. The magnetic clutch protects internal gearing under stall conditions while maintaining consistent output force. Suitable for terminal unit control, fan coil units, air handling units, and a wide range of HVAC hydronic and steam applications.
