Product Highlights

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.

FAQs

Q: Do your valves have NSF, DVGW, ACS, WRAS certifications for drinking water? Can you provide documents?

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

Q: What's the advantage of bistable pulse valve? Power consumption and lifespan?

A: 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.

Q: Can you do OEM customization like voltage, port size, and logo?

A: 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.

Q: Any use cases in irrigation or water treatment systems?

A: 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.

Q: Can I get samples? What is your MOQ? Can you ship goods to my agent in China?

A: Sure, we can provide samples for you.
Our regular MOQ is 500 pcs per model, and we can negotiate the quantity for trial order.
No problem to ship the goods to your Chinese agent, just send us the agent warehouse address, we will arrange delivery.

Q: What is the fastest delivery for 500pcs of standard valves?

A: For urgent standard orders, we have a fast-track process. Delivery for 500pcs can be within 7-10 days, and we will strive to ship even earlier whenever possible.

Q: Do you provide neutral packaging? Who are your shipping agents?

A: Standard neutral packaging is available. We work with major agents (DHL, FedEx, sea freight) and will arrange the most cost-effective & reliable shipping based on your needs.

Q: What is your product warranty and technical support policy?

A: We provide a strong 3-year warranty. For any non-operational defects, we offer repair or replacement. Our engineering team provides free lifetime technical support for application solutions.
