Frequently Asked Questions

Q: What is the operating principle of this quick closing valve?
A: The valve uses a pneumatic actuator connected to a 24V DC solenoid. When the solenoid receives a signal, it directs compressed air to open or close the valve rapidly. In spring-return models, loss of air or power automatically closes the valve.
Q: Can the valve be used for high-temperature media?
A: The standard temperature range is -20°C to +80°C. For higher temperatures, please contact our sales team for customized seal and body material options.
Q: What is the closing time of the valve?
A: Closing time depends on valve size, actuator configuration, and air supply pressure. Typically, it ranges from 1 to 5 seconds. Detailed data can be provided upon request.
Q: Is the valve compatible with both liquid and gas?
A: Yes, it is suitable for a wide range of non-corrosive and mildly corrosive media. For aggressive chemicals, we recommend selecting appropriate seal materials (e.g., PTFE or Viton).
Q: Does the valve come with position feedback?
A: An optional limit switch box or proximity sensor can be mounted on the actuator to provide remote position indication.
Q: What maintenance is required?
A: Periodic inspection of seals, actuator, and solenoid is recommended. The valve’s modular design allows easy replacement of components without removing the valve body from the pipeline.
Q: What certifications do you have?
A: Our manufacturing facility is ISO9001 certified. The valve itself is manufactured according to GB/T1850 standard. Additional certifications such as ATEX or SIL can be provided upon request for specific projects.
Q: How can I get a quotation?
A: Please provide the required valve size, connection type, media, and any special requirements. Our sales team will respond within 24 hours with a competitive quote.
