Heating Controls & Valves

Product Characteristics

1）Use of radio frequency(RF) card, eliminates the defect that the ineterface (used for contact between the smart card and the valve) is easy to get tampered with.

2）Utilizing the smart card to fulfil the prepayment function, with built-in clock circuit, the controller shuts the valve off automatically after it reaches the set ending date of heat distribution.

3）Each valve is assigned with an unique smart card and an address to facilitate the consumption payment and management.

4）Valve body uses of throughflow sensor design, delivers almost zero pressure drop

5）Valve body uses of ultra thick design, ensures high intensity.

6）Use of large torque of actuator ensuring that the valve can work properly under all kinds of working pressure.

7）Factory-fitted M-BUS lead communication interfaces, facilitates the remote reading, billing and control.

8）Allows the authority to remotely handle with emergent or coercive shut on/off the valve according to the practical condition.

9）Equipped with interface for external DC24V power supply, drastically prolongs the life time of the built-in 3.6V lithium battery. Boosts the stability and reliability of the long-term running of the system.

10）Built-in 3.6V standby lithium battery, facilitates the normal operations of the card reading and the valve activities in case powered off.

11）Can work separately in either the remote control or control by smart card fashion. i.e. it can be used as the heating control valve in case of communication failure as well as it can remotely load credits and shut on/off the valve in case there is no smart card.

12）Valve can be remotely controlled through the management system, enabling mass credit loading or activities control.

13）Integrated compact structure design, excellent sealing to deliver highly resistant to water.

14）LED light indications for valve on/off status are available, communication status, card reading status.

15）Networking and power line uses of specialized 4-core waterproofing bus lead plug, facilitates the networking.

16）Built-in temperature sensor to measure water temperature in the valve body, enabling the authority to capture the water distribution

17）Built-in alarm circuit to alert of tampering attempts, it logs the current status timely when the controller is are separated from the valve body, and reports to the collector, the authority can handle with it timely after finding the issue through the management system.

18）Built-in control circuit of the valve opening level and indication of the valve opening level, authority can set the maximum opening level of the customer's valve, achieves the purpose of saving energy.
