match with VB7000 series flanged valves or any other valves. suitable for heating, ventilating, air-conditioning system

VA7000 series electric modulating valve actuators can match with VB7000 series flanged valves or any other valves through different connectors. That are suitable for heating, ventilating, air-conditioning system (HVAC).Features1. Synchronous and reversible motor with low AC voltage, magnetism clutch2. Gear transfer: Output gear stem is supported by planar rolling shaft with central location.3. Valve stem uses central connection of screw cap and position round piece4. Manual control stem is attached5. Stroke: 24mm, 36mm or 40mm, 42mm6. The stroke of proportional control actuator is selected by one line ruler.7. Direct or reverse running can be selected by 0-10V proportional direct current control.
