V-3801-8001 Johnson Controls Actuator

Overview

The Johnson Controls V-3801-8001 is a compact pneumatic valve actuator designed to accurately position steam or water valve modulating plugs in response to a pneumatic signal from a controller. Featuring a small, oval top, it is ideally suited for 1/2-inch and 3/4-inch VG7000 Series bronze globe valve applications with restricted mounting space. All internal components are protected by a sturdy die-cast aluminum housing.

Features

• Compact design with a small oval top allows for easy installation in restricted spaces such as baseboard radiators and convectors.
• Molded synthetic rubber rolling diaphragm provides a constant effective area throughout the actuator stroke for optimal force output.
• Single set screw design enables quick assembly and easy field mounting to the valve bonnet.
• Sturdy die-cast aluminum enclosure with an enclosed spring protects internal components from damage.

Specifications

• Maximum Control Pressure: 30 psig (207 kPa)
• Effective Diaphragm Area: 4 sq in.
• Air Connection: 1/8 in. NPT barbed fitting for 1/4 in. or 5/32 in. O.D. polytubing
• Ambient Operating Temperature Limits: -20 to 150°F (-29 to 66°C)
• Maximum Storage Temperature: 150°F (66°C)
• Construction Materials: Die-cast aluminum housing; synthetic rubber diaphragm
• Shipping Weight: 0.5 lb (0.23 kg)

Applications

• Designed for commercial HVAC systems to control hot water, chilled water, or saturated steam systems with 15 psig (103 kPa) or less inlet pressure.
• Engineered for direct mounting on 1/2-inch and 3/4-inch Johnson Controls VG7000 Series bronze control valves.
• Not recommended for pneumatic sequencing applications due to its compact size and low output force.
