Product Name：Johnson Controls VA-7010-8503-C Valve Actuator
Core Features
1. Advantage：
The VA-7010-8503-C is a compact, spring-return electric actuator that mounts directly onto Johnson Controls VG4000 series zone valves in fan coil and small HVAC systems. Rated for 230VAC line voltage, it drives the valve open on call for cooling or heating, and automatically returns to the safe position when power is removed. The compact metal housing fits tight mechanical spaces, and the two-wire connection makes field installation straightforward.

3.Our Advantage
Zone valve actuators are one of the most common failure points on fan coil systems-when the actuator motor burns out, the valve stays stuck and rooms get too hot or too cold. We supply Johnson Controls replacement actuators that clip directly onto existing VG4000 valve bodies, so you do not have to drain water or repipe the whole valve. If you are unsure whether the problem is the actuator or the valve itself, our support team can help you diagnose over email.

FAQ
Q: How can we contact you?
A:1. WhatsApp / Wechat: +86 15893891309 Violet Yan
Q: 2.How do I know if my actuator is bad?
A：If the zone valve is not opening or closing when the thermostat calls, and you hear no humming from the actuator motor when power is applied, the actuator has likely failed. You can swap in a new VA-7010 actuator without replacing the whole valve body.
Q: 3.Does this fit VG4000 valves specifically?
A: Yes. The VA-7010 series is designed for the VG4000 zone valve platform. The actuator clips on top of the valve body with a simple mounting bracket-no tools or pipe work required.
