Johnson Controls V146GL1-001 1″ Union Sweat Two-Way Pressure Actuated Water Regulating Valve

Description

Overview

The Johnson Controls V146GL1-001 is a two-way, pressure actuated water regulating valve engineered for use with non-corrosive, high-pressure refrigerant systems. Featuring a 1″ union sweat connection and a 200 to 400 PSI opening point range, this valve automatically modulates condenser water flow in response to refrigerant head pressure — helping maintain optimal system efficiency and protecting compressor components from the damaging effects of high or low head pressure.

Key Features

• Two-way, pressure actuated design for automatic condenser water flow control
• 1″ union sweat end connections for straightforward installation and serviceability
• 200 to 400 PSI opening point range — suitable for non-corrosive high-pressure refrigerant applications
• 1/4″ external flare connector (Style 5) pressure element for reliable refrigerant pressure sensing
• Modulates water flow to maintain stable head pressure and protect system components
• Durable construction designed for demanding commercial and industrial HVAC/R environments

Specifications

Application

Ideal for commercial refrigeration and air conditioning systems where precise head pressure control is critical. The V146GL1-001 responds directly to refrigerant pressure changes, opening to allow condenser water flow when pressure rises and closing to restrict flow when pressure drops — ensuring consistent, energy-efficient operation across varying load conditions.
