Johnson Controls VG1245BG Valve

The Johnson Controls VG1245BG is a 3/4-inch, two-way NPT motorized ball valve engineered for precise control in commercial HVACR systems. Utilizing a high-performance 4.7 Cv rating, this valve is built with a forged brass body and 300 series stainless steel trim, making it ideal for managing chilled water, hot water, and 50/50 glycol solutions. Unlike brass-trim alternatives, the stainless construction allows for service in low-pressure steam applications up to 15 psig when paired with a thermal spacer.

The VG1000 series design features a specialized Amodel flow characterizing disk, which ensures an equal percentage flow characteristic. This allows for linear temperature control and high rangeability of 500:1, preventing hunting in the control loop. Reliability is critical for service contractors; this unit incorporates dual EPDM stem seals and 15% graphite-reinforced PTFE seats, providing a rated life of 200,000 cycles even in iron-oxide contaminated water. With a 200 psi close-off pressure and ANSI Class IV leakage rating, it delivers tight shut-off and system integrity.

Key Benefits

• Equal Percentage Flow: Accurate modulation for fan coils and heat exchangers.
• Stainless Steel Trim: Enhanced corrosion resistance and 15 psi steam compatibility.
• High Close-Off: Rated for 200 psid to prevent bypass leakage in high-head applications.
• Maintenance-Free Seals: Double O-ring stem design eliminates the need for field packing adjustments.
• Actuator Compatibility: Direct-mounts to VA9104, VA9300, and VA9203 series electric actuators.

Common Questions

What is the maximum fluid temperature for this valve?
The stainless steel trim allows for a fluid temperature range of -22?F to 284?F (-30?C to 140?C).

Can this valve be field-repaired?
The VG1245BG is a maintenance-free design. If the internal seals or seats fail after its 200,000-cycle life, the valve body should be replaced as a unit to ensure 100% shut-off reliability.

Does this include the actuator?
This SKU is for the valve body only. It is designed for field-mounting to compatible Johnson Controls electric actuators.
