V46AS-2C Johnson Controls Water Regulating Valve

Overview

The Johnson Controls R-131-2 is a precision-engineered pneumatic air pressure reducing valve designed for commercial and industrial HVAC systems. It provides highly accurate pressure regulation to protect downstream components and maintain consistent operating pressures. The valve features a failsafe design that stops output pressure if a malfunction occurs, preventing potential damage to sensitive system instrumentation, and is finished in a distinct moss green.

Features

• High Precision Regulation: Accurately maintains steady downstream pressure within ±0.1 psi when operated within its rated capacity.
• Failsafe Operation: Stops output pressure transmission in the event of a valve malfunction to protect connected equipment.
• Secure Adjustments: Equipped with a lockable hand-wheel adjusting knob to set and secure the desired pressure, preventing unauthorized or accidental setpoint changes.
• Dual Auxiliary Ports: Includes two 1/4-inch auxiliary ports to allow flexible orientation for connecting an output pressure gauge.
• Integral Filters: Built-in filters prevent dirt and contaminants from entering the valve assembly, ensuring reliable performance.
• Flexible Mounting: Designed for inline mounting or can be panel-mounted using an optional mounting bracket.

Specifications

• Connection Size: 1/4 inch NPT
• Inlet Pressure Range: 0 to 200 psig
• Outlet Pressure Range: 3 to 150 psig
• Gauge/Auxiliary Ports: 1/4 inch
• Media Compatibility: Clean, dry compressed air only
• Construction: Compact housing with a moss green finish

Applications

• Designed for precise air pressure reduction in pneumatic commercial building automation and HVAC control systems.
• Ideal for regulating primary air lines to protect sensitive downstream pneumatic controllers, actuators, and air handling units from over-pressurization and system drift.
