Product description

Highlights at a glance

  • Pulse driven with zero standby power consumption saves electricity and is ideal for battery powered applications.
  • Permanent magnetic self locking maintains position upon power failure, ensuring safe and reliable operation with no unintended switching.
  • The coil does not generate heat, resulting in extended service life and a low failure rate.
  • The bistable design ensures the valve position remains unchanged after power loss.
  • Fast response enables precise control with millisecond level switching.
    • Frequently asked questions

    Yes. Our products hold key international certifications: NSF/ANSI 61 (), DVGW KTW (), ACS (), and WRAS () for drinking water safety. We provide full certification packages to support your market compliance and project approval processes.

    Bistable valves use power only for milliseconds during switching (zero holding power), saving >90% energy vs standard valves. No coil heating extends lifespan to over 1 million cycles, reducing long-term costs.

    Yes, we specialize in OEM/ODM services. We can customize electrical specs, threads, and branding. To ensure fit, we can provide 3D-printed prototypes for testing before mass production. Lead time is ~20-30 days.

    Our valves are widely used in smart irrigation, water purification, and circulation systems. We can share general application notes and recommend suitable models based on your specific project parameters.

    We offer 1 free sample for product verification. The customer covers the shipping cost. MOQ is flexible and negotiable for initial orders. Please
