  • $160.56


The Johnson Controls VG7842ET Valve is a high-performance 3-way mixing globe valve engineered specifically for technical precision in HVAC hydronic systems. Constructed with a cast bronze body and durable brass trim, this 1/2-inch NPT valve provides reliable control over hot water, chilled water, and saturated steam up to 15 psig. With a 1.8 Cv rating and linear flow characteristics, it ensures stable modulation and mixing of fluids to maintain exact setpoints in commercial and industrial piping loops.

Designed for seamless integration with VG7000 Series actuators, this valve features a standard threaded stem and flexible mounting geometry to accommodate both pneumatic and electric valve actuators. The self-adjusting packing and ANSI Class IV leakage rating ensure long-term integrity and minimized maintenance in high-demand environments. Whether you are performing a field replacement or a new installation, the VG7842ET delivers the structural durability required for systems with a maximum water pressure of 400 psi at 150?F.

Key Benefits
  • Broad Application Range: Rated for use with hot water, chilled water, and 15 psi saturated steam, making it a versatile choice for diverse HVACR mechanical systems.
  • Refined Flow Control: The 1.8 Cv linear flow design provides consistent mixing performance, essential for maintaining stable temperatures in air handling units and heat exchangers.
  • Extended Service Life: Features a high-quality bronze body and brass internal components that resist corrosion and withstand demanding thermal cycles.
  • Simplified Actuation: The standard threaded stem allows for quick coupling with a wide array of Johnson Controls actuators, reducing labor time during installation.
