Q: How does a zone valve work? A: A zone valve consists of two main parts: an actuator and a valve body. The actuator contains a motor, a spring, and other mechanical components. Quality tested for over 100K cycles for flawless operation. Our valves have a static pressure rating of 290 PSI and a close-off pressure ranging from 20 to 50 PSI, depending on valve size. The building is divided into separate zones, each controlled by a zone valve, enhancing energy efficiency and comfort by only heating or cooling necessary areas. Zone valves are designed specifically for closed-loop hydronic systems, which are separate from domestic water supply systems and use water and glycol as media. Cases Packed Savings - Valemo Controls Close-Off Pressure: The maximum pressure under which the valve’s internal components can fully open or close the valve without malfunctioning. Heavy-duty motor with all metal gears. Our VALEMO brand is becoming globally recognized by millions of consumers for its reliability and durability. The system is often filled with water mixed with up to 50% glycol solution to prevent freezing during winter months. Larger valves generally have lower close-off pressure due to the increased force needed to move a larger internal paddle. Corrosion-resistant, stainless steel housing. Aluminum cover. Atomic Redster Q5 Ski w/ M10 GW Binding 2024 - Australia Using them in an open-loop system, such as city water, will cause internal damage. Dissolved oxygen in city water can corrode the valve’s components, shortening its service life, and high water pressure may prevent the valve from closing completely, leading to leaks. When power is supplied, the motor winds up the spring, moving the valve’s internal paddle to the open position. What is the difference? A: Valves with an end switch have two additional wires (usually blue and red) that indicate the position of the valve paddle. Q: What is the application of a zone valve? A: Zone valves are typically used in closed-loop hydronic heating/cooling systems in residential or commercial buildings that use fan coils, baseboards, or radiators. Q: What is the difference between “static pressure” and “close-off pressure” in your user manual? A: Static Pressure: The maximum pressure the valve body can withstand during testing without leakage, indicating the valve’s structural strength. (Normally Closed): Valve remains closed when no power is supplied. N.O. Normally, these wires are open-circuit.
