VG1241AL+9A4GGA Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG1241AL+9A4GGA is an actuated valve assembly that combines a 1/2-inch 2-way forged brass ball valve with a VA9104-GGA-2S non-spring return electric actuator. Designed to regulate the flow of hot or chilled water in commercial HVAC systems, this assembly features a 7.4 Cv flow capacity and an equal percentage flow characteristic for precise temperature control. It operates via a 0-10V proportional control signal and does not include an auxiliary switch.

Features

• High static pressure rating of 580 psig provided by a rugged forged brass body.
• Tight shutoff with a 200 psi closeoff pressure rating.
• Equal percentage flow delivery via an Amodel flow characterizing disk.
• Leak-free performance over a minimum 200,000 full cycle life expectancy using a double O-ring EPDM stem seal.
• Blowout-proof stem design ensures optimal operator safety.
