Some questions about Antifreeze Valve

Do your valves have a self-draining design to prevent ice buildup?

Yes! BORNIC anti-freeze valves feature an optimized self-draining design that automatically evacuates residual water to prevent ice blockage. Our patented sloped-body construction ensures complete drainage even in sub-zero conditions.

Are your anti-freeze valves certified to EN 12266-1 for pressure testing?

Absolutely. All BORNIC valves undergo EN 12266-1 pressure tests at our ISO 17025-accredited lab. We provide full test reports with every shipment for your quality records.

Can these valves be installed underground or in exposed outdoor locations?

Designed for both! Our valves come with:
✔ UV-resistant epoxy coating for outdoor exposure
✔ Stainless steel stem extensions for buried installations
✔ Optional insulated enclosures for extreme climates

What is the lead time for custom orders (special sizes/materials)?

Standard lead time: 15 working days for customized valves (vs. industry average 30+ days).
Need it faster? Ask about our express 7-day service for urgent EU projects.

Can you customize valve sizes for non-standard piping systems?

Our specialty! We’ve produced valves for:
• DN25-DN1200 sizes
• Special alloys for Arctic applications
• 3D-printed prototypes available for validation

Do you offer different connection types?

Three battle-tested options:
① Flanged (EN 1092-1 PN10/16)
② Threaded (BSPP/NPT)
③ Grooved (EN 12842)
Pro Tip: Our multi-connection adapters solve retrofit challenges.
