Trane VAL11357 Water Valve

The Trane VAL11357 Water Valve is a 1/2" 3-Way Water Valve designed for precise fluid control in hydronic HVAC systems. Engineered to meet strict OEM specifications, this motorized assembly ensures accurate modulation of chilled and hot water flows, maintaining setpoint stability in fan coil units and air handlers. As the direct replacement for VAL8107, the VAL11357 facilitates a streamlined retrofit process, matching the legacy footprint and electrical requirements to minimize field labor. This HVAC motorized water valve features a robust brass body construction and a high-torque actuator capable of overcoming significant close-off pressures. Contractors utilizing this 3-way mixing valve can expect reliable diversion and mixing performance, crucial for preventing thermal shock and optimizing heat exchanger efficiency. Integration with building automation systems is seamless, provided the voltage and control signal align with the existing Trane replacement parts framework. Proper installation of this zone valve actuator pack ensures hydraulic balance across the mechanical loop.

• Direct OEM Compatibility: Specifically engineered as the VAL8107 replacement valve, ensuring electrical and physical fitment without piping modifications.
• High Close-Off Rating: Built to withstand commercial-grade static pressures, preventing bypass leakage and improving system delta-T.
• 3-Way Diverting Logic: Optimized for constant flow systems where maintaining loop pressure is critical during terminal unit cycling.
• Industrial Build Quality: Features a corrosion-resistant internal trim and a durable Trane actuator assembly for extended cycle life in demanding environments.

Common Technical Questions

Is the VAL11357 compatible with standard 24V control circuits?
Yes, this 3-way control valve is designed to interface with standard HVAC control voltages, but technicians should always verify the specific actuator signal (on/off, floating, or proportional) against the site controller before wiring.

Can this valve be used in both heating and cooling applications?
The Trane VAL11357 is rated for standard hydronic temperature ranges, making it suitable for both chilled water and hot water coils, provided the glycol concentration remains within the specified limits for the seals.

What is the flow coefficient (Cv) for this 1/2" valve?
This 1/2 inch NPT water valve typically maintains a Cv rating optimized for terminal units, ensuring sufficient flow for heat transfer while providing the necessary pressure drop for authority in the loop.
