Features
-
Intelligent control integration
Built-in CAN bus communication module, compatible with automotive and industrial automation control systems, supports real-time angle feedback and remote command operation.
Optional proportional adjustment function to achieve precise closed-loop control of flow/pressure. -
Multi-channel mode
L-type channel: orthogonal dual-channel independent control, suitable for medium distribution (such as cooling water diversion).
T-type channel: three-way full-pass or mixed mode to meet confluence and reversing requirements (such as heat exchange system). -
Durable design
The valve body is made of 316L stainless steel or PTFE coating, and the fluid contact parts are free of metal materials, which is corrosion-resistant and does not affect insulation. It is suitable for special media such as deionized water and hydrogen fuel cell coolant.
Wide voltage input (12-24VDC), compatible with passenger cars, commercial vehicles and industrial equipment power supplies. -
High efficiency and energy saving
Low flow resistance structure reduces energy consumption, dynamic response time <0.5 seconds, and improves system energy efficiency.
FAQ
Q: How precisely does it manage the flow distribution between the three ports in our complex industrial process?
A: It manages the flow distribution with high precision. The internal mechanisms are engineered to adjust the position of the valve element accurately, allowing for exact control over the proportion of fluid flowing through each port. For instance, in a chemical mixing process where specific ratios of different substances are required, it can direct the flows with an accuracy of within a few percentage points. This precision ensures the consistency and quality of the end - product in your industrial operations.
Q: What is its response time when we need to switch the flow pattern during operation?
A: It has a rapid response time. When a signal is sent to change the flow pattern, the electric actuator can move the valve element to the new position in a matter of milliseconds. In applications like a power plant's steam - distribution system, where quick adjustments are necessary to respond to load changes, this short response time enables seamless transitions. It helps prevent disruptions in the overall system and ensures efficient operation.
Q: How durable is it in the long - term considering the harsh conditions of our industrial environment, such as high - pressure fluids and temperature fluctuations?
A: It is built to be highly durable. The materials used for its construction, such as high - grade alloys for the valve body and heat - resistant seals, can withstand high - pressure fluids and significant temperature fluctuations. In an oil refinery, for example, where it may be exposed to hot, high - pressure crude oil and sudden temperature changes during different processing stages, it can maintain its integrity over an extended period. Regular maintenance, like periodic inspections and component replacements when necessary, further extends its lifespan.
Q: Can it be integrated with our existing automated control network, and what are the integration requirements?
A: Yes, it can be integrated with your existing automated control network. It is designed to be compatible with standard industrial communication protocols like Modbus, Profibus, or Ethernet/IP. The integration requirements mainly involve proper electrical wiring to connect it to the control system's power supply and communication lines. Our technical support team can provide detailed installation guidelines and on - site assistance to ensure a smooth integration, allowing for seamless control and monitoring within your automated setup.
Q: How energy - efficient is it during continuous operation, and how does this impact our overall energy costs?
A: It is relatively energy - efficient during continuous operation. The electric actuator is designed to consume minimal power while maintaining the correct valve position. When the valve is in a steady - state, the power draw is low. Even during the movement to change the flow pattern, the actuator is optimized to use only the necessary amount of energy. In a large - scale manufacturing facility with multiple such valves operating continuously, the cumulative energy savings can be substantial. This directly contributes to reducing your overall energy costs, making it a cost - effective choice for long - term operation.
