VA - Zone spring-back valves

The VA series zone valves are flow control devices designed for use in heating, air conditioning, and heat transfer fluid distribution systems. Made of high-strength brass, they are available in two-way and three-way versions, allowing both shut-off and flow diversion functions. The sealing element is made of VITON gaskets, a high-quality material that ensures excellent resistance to high temperatures, chemical agents, and wear, thereby providing long-lasting performance and reliability over time. The actuator is driven by a high-torque synchronous motor, combined with a spring return mechanism that allows the valve to automatically close in the event of a power failure, ensuring safety and operational continuity. The valve is also equipped with a manual operating lever, allowing the user to open or close the fluid passage without using the motor. Its compact and robust construction, together with the precision of the control assembly, makes VA valves particularly suitable for both residential and industrial applications where reliable and accurate flow regulation is required.
