Frequently Asked Questions (FAQ)
-
Q: What is the fail-safe option, and how does it work?
A: The fail-safe option ensures the valve moves to a predetermined position (open or closed) when power is lost. It can be achieved via a spring-return mechanism (mechanical) or a battery backup (electrical), providing automatic safety in critical applications. -
Q: Can this valve be used with aggressive chemicals?
A: Yes, the 316 Stainless Steel body and disc offer excellent resistance to many corrosive chemicals. However, we recommend consulting our technical team for specific chemical compatibility, as seat material (PTFE, EPDM, or Viton) can be customized. -
Q: What is the typical lead time for this valve?
A: Standard sizes (DN50-DN300) are typically shipped within 15-25 working days after order confirmation. Custom sizes or special configurations may require additional time; please inquire for exact delivery schedules. -
Q: Is the 4-20mA signal compatible with all control systems?
A: The 4-20mA analog signal is a universal industrial standard and is compatible with most PLC, DCS, and SCADA systems. We also provide optional feedback signals (e.g., 0-10V) upon request. -
Q: What is the maximum operating pressure for this valve?
A: The standard pressure rating is PN10 or PN16 (1.0 MPa or 1.6 MPa). For higher pressure requirements, we can offer customized designs—please contact us with your specific needs. -
Q: Do you provide installation and maintenance manuals?
A: Yes, each valve comes with a detailed user manual covering installation, wiring, calibration, and maintenance procedures. Our technical support team is also available for remote assistance. -
