Belimo ZONE315S-35 Valve
The Belimo ZONE315S-35 is a high-performance 3-way zone valve designed for precise flow control in hydronic systems. Featuring a 1/2 inch sweat connection and a 3.5 Cv rating, this valve is engineered for efficiency in chilled or hot water applications. The forged brass body ensures long-term durability, while the EPDM O-rings and stainless steel stem provide reliable sealing and smooth operation under varying pressure differentials. This compact zone valve is ideal for tight mechanical spaces, allowing for clean installations in fan coil units and baseboard heaters. With its 90-degree rotation and high close-off pressure capacity, it prevents leakage and optimizes energy transfer. Installers can rely on its compatibility with Belimo actuators, facilitating seamless integration into existing building automation systems. This component is built to handle professional-grade HVAC demands, ensuring consistent hydraulic balance and temperature regulation across commercial and residential zones.
Key Technical Benefits:
- High Flow Capacity: The 3.5 Cv rating ensures optimal fluid dynamics for medium-flow hydronic loops.
- Secure Fitting: Sweat connections provide a leak-proof, permanent bond for high-vibration environments.
- Corrosion Resistance: Constructed with a high-grade brass body to withstand chemical additives in treated water systems.
- Actuator Versatility: Designed for easy snap-on mounting with Belimo zone actuators, reducing labor time during field replacement.
- Low Torque Requirements: Precision-machined internals reduce the force required for actuation, extending the service life of the motor.
Common Technical Questions:
What is the maximum fluid temperature for the ZONE315S-35?
This valve is typically rated for fluid temperatures ranging from 32°F to 212°F, making it suitable for both heating and cooling cycles.
Can this 3-way valve be used in a diverting application?
Yes, the Belimo 3-way valve design allows it to function effectively in both mixing and diverting configurations depending on the piping layout.
What actuators are compatible with the ZONE315S-35 series?
It is specifically designed to work with the Belimo ZoneTight series actuators, providing high close-off ratings and efficient power consumption.
