Belimo ZONE315N-35 Valve
The Belimo ZONE315N-35 is a high-performance 3-way zone valve designed for precise hydronic control in commercial and residential HVAC systems. Featuring a 1/2 inch NPT female connection and a 3.5 Cv flow coefficient, this valve is engineered for on/off hydronic control and diverting applications. Built with a forged brass body and an EPDM paddle, it ensures reliable shut-off against high differential pressures. This Belimo zone valve is compatible with standard NPT piping and uses a spring-return or non-spring return actuator for seamless integration into fan coil units and baseboard radiation systems. The design minimizes water hammer and provides consistent close-off pressure, making it a staple for contractors prioritizing long-term system stability. Whether you are performing a zone valve replacement or a new HVAC installation, the ZONE315N-35 delivers the flow accuracy and durability required for demanding hydronic circuits.
Key Benefits for Contractors
- High Flow Capacity: The 3.5 Cv rating ensures optimal flow for 1/2" piping applications without excessive pressure drop.
- Durable Construction: Forged brass body prevents de-zincification and stands up to standard glycol concentrations.
- Versatile Application: Ideal for diverting or mixing in hot water or chilled water loops up to 50% glycol.
- Reliable Sealing: High-quality EPDM seal provides tight shut-off to prevent leakage in closed-loop systems.
- Ease of Installation: Compact footprint allows for installation in tight mechanical closets and plenum spaces.
Common Questions
What is the maximum differential pressure for this valve?
The Belimo ZONE315N-35 is typically rated for a close-off pressure of 30-50 psi depending on the actuator torque, ensuring reliable operation under standard pump heads.
Can this valve be used in steam applications?
No, this 3-way zone valve is strictly designed for hydronic systems (water or water-glycol mixtures) and should not be used for steam service.
Which actuators are compatible with the ZONE315N-35?
This valve body is designed to pair with Belimo Zone Series actuators, offering various voltage options and control signals to match your specific control system requirements.
