Johnson Controls VG1245BNH923GGA Valve

The Johnson Controls VG1245BNH923GGA Valve is an industrial-grade 3/4 inch NPT ball valve assembly designed for precision fluid control in commercial HVACR systems. Built with a forged brass body and stainless steel trim, this 2-way normally open valve is optimized for demanding applications involving chilled water, hot water, and 50% glycol solutions. Featuring an 11.7 Cv rating and equal percentage flow characteristics, it ensures stable and accurate heat transfer across a wide range of terminal unit loads. The integrated spring return actuator provides a critical fail-safe position, while the thermal barrier and 500-ohm resistor support versatile 4-20mA, 0-10Vdc, or 2-10Vdc proportional control signals for seamless building automation integration.

• Corrosion Resistance: The stainless steel ball and stem prevent premature wear and scale buildup in hydronic loops.
• Precise Modulation: Engineered with a specialized characterizing disk to provide equal percentage flow, eliminating hunter-cycles in the control loop.
• Fail-Safe Reliability: The mechanical spring return ensures the valve returns to the normally open position during power loss to maintain system flow.
• High Temperature Support: Equipped with a thermal barrier to protect the actuator electronics in high-temp hydronic environments.
• Operational Longevity: Built for 200,000 cycles in iron-oxide contaminated water, reducing long-term maintenance requirements for field technicians.

• Is this valve compatible with steam systems? The VG1245BNH923GGA with stainless steel trim is rated for low-pressure saturated steam up to 15 psig.
• What power supply is required for the actuator? This assembly operates on standard 24Vac or 24Vdc power for flexible field wiring.
• Can I use a 4-20mA control signal? Yes, the inclusion of a 500 ohm resistor allows this unit to interpret 4-20mA analog signals for precision modulation.
