Johnson Controls VG1245ER Valve

The Johnson Controls VG1245ER is a heavy-duty 1-1/2 inch NPT ball valve engineered for precision flow control in commercial HVACR systems. This two-way control valve utilizes a forged brass body with stainless steel trim, ensuring high durability and resistance against corrosion in chilled water or hot water applications. Featuring a 29.2 Cv flow coefficient and an equal percentage flow characteristic, this unit provides exceptional modulation and throttling performance, preventing hunting and maintaining stable loop temperatures. The VG1000 series design allows for seamless integration with various Johnson Controls actuators, facilitating field installation and high-torque operation. Its blowout-proof stem and triple-seal technology maximize service life in high-pressure environments. For contractors requiring a reliable NPT threaded ball valve for HVAC hydronic systems, the VG1245ER delivers the mechanical integrity needed for precise BMS flow regulation and consistent long-term performance.

• Equal Percentage Flow: Optimized for linear thermal output, ensuring stable control at low and high loads.
• Stainless Steel Trim: Prevents scaling and premature wear in demanding water loop conditions.
• High Flow Capacity: The 29.2 Cv rating supports significant 1-1/2" line requirements without excessive pressure drop.
• Universal Compatibility: Designed for direct-mount pairing with non-spring and spring-return actuators for flexible field configuration.
• Long-Term Sealing: High-performance Teflon seats and dual EPDM O-rings provide a bubble-tight shutoff.

What is the maximum fluid temperature rating for the VG1245ER?
This valve is typically rated for fluid temperatures ranging from 0°F to 284°F, provided the appropriate actuator and media concentration are utilized.

Can this valve be used for steam applications?
The VG1245ER is specifically designed for chilled and hot water applications; it is not recommended for high-pressure steam service.

Is this valve field-serviceable?
While the assembly is robust, the internal components are factory-set to ensure seat integrity; standard practice involves replacing the valve body if significant internal damage occurs.
