VG1845CL+9T4GGA Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG1845CL+9T4GGA is a factory-assembled 1-inch, 3-way mixing or diverting ball valve paired with a VA9104-GGA-3S non-spring-return electric actuator. It is designed to precisely regulate the flow of hot water, chilled water, glycol solutions, and low-pressure steam in commercial heating, ventilating, and air conditioning systems. The assembly features a durable forged brass body, stainless steel trim, and an analog 0-10V proportional control input for seamless building automation integration.

Features

• Proportional Control: Operates via a 0-10 VDC modulating analog signal for automated precision flow management.
• Non-Spring Return Actuator: Utilizes a VA9104 series electric actuator that maintains position upon power loss, providing efficient performance without a switch.
• Stainless Steel Trim: Equipped with a stainless steel ball and stem for enhanced durability and resistance to harsh media.
• Superior Life Expectancy: Tested to provide a minimum of 200,000 leak-free operational cycles.
• High Close-Off Pressure: Ensures robust sealing performance up to 200 psi to eliminate internal leakage.
