Engineered for industrial & commercial piping systems — reduce pressure drop by up to 40% compared to standard check valves. Trusted by US plant engineers and procurement managers who demand reliable backflow prevention without sacrificing flow efficiency.
If you're sourcing full bore check valve 15mm for critical applications, you've likely run into these costly issues:
Many "full bore" valves still have restricted internals. Your pump works harder, energy bills climb 12-18%.
Low-grade brass or thin stainless steel leads to corrosion, pitting, and failure within 6-8 months in aggressive media.
Suppliers who quote low per-unit prices often inflate freight or use slow sea freight — your project gets delayed.
Without strict QC, you get leaking, sticking, or mismatched thread forms. Rejection rates eat your margin.
Standard 15mm check valves from some factories take 45-60 days. Your maintenance window can't wait that long.
You need sizing help, material compatibility data, or custom spring settings — most suppliers just send a data sheet.
These aren't just annoyances. They cost you $2,000–$8,000 per year in downtime, energy waste, and rework. There's a better way.
Our full bore check valve 15mm is designed from the ground up for industrial reliability. The bore diameter matches the pipe ID exactly — no flow restriction, minimal turbulence, and a cracking pressure as low as 0.05 bar.
Internal diameter equals 15mm nominal bore — zero obstruction. Pressure drop is 37% lower than standard reduced-port check valves. Your pumps run cooler and last longer.
Available in SS304, SS316, brass, and duplex. Each batch is spectrograph-tested. Suitable for water, oil, steam, and mild chemicals.
We stock 6,000+ units of 15mm full bore check valves in our Hebei warehouse. Air freight available in 5-7 days. No more production line stoppages.
Need a special spring tension, thread type (NPT/BSP/BSPT), or laser marking? Our engineers deliver custom configurations in as little as 10 working days.
Every single valve is hydrostatically tested at 1.5x rated pressure. You get a test certificate with every order. Zero-defect policy — we replace any faulty unit at our cost.
Our sales engineers work US hours (EST/PST). Get sizing recommendations, CAD files, and material certificates within 2 hours.

Full bore (also called full port) means the internal diameter of the valve is equal to the pipe's nominal bore. For our 15mm full bore check valve, the ball or disc does not obstruct the flow path, resulting in minimal pressure drop — typically 30-40% less than standard reduced-port check valves.
We offer NPT (most common for US), BSP, BSPT, and parallel threads. Custom thread forms are available for OEM orders. Please specify your requirement when requesting a quote.
Standard lead time is 15-25 working days for quantities up to 1,000 units. Express delivery (air freight) is available in 5-7 days. We stock popular materials and thread types for immediate shipment.
Yes. We provide free samples for qualified B2B buyers. You pay only the shipping cost. Samples are fully tested and include a test certificate. Request your free sample here.
For aggressive chemicals, we recommend SS316 or SS316L with FKM (Viton®) seals. For high-chloride environments, Duplex 2205 is ideal. Our engineers can help you select the right material based on your media, temperature, and pressure.
Every batch goes through: (1) incoming material spectrograph testing, (2) in-process dimensional checks, (3) 100% hydrostatic pressure test at 1.5x rated pressure, and (4) functional flow test. We provide batch traceability and a Certificate of Conformance with every shipment.
Our standard MOQ is 50 units. For custom/OEM configurations, MOQ is 200 units. Smaller trial orders are available at a slightly higher per-unit price.
Yes. Our sales engineers work US business hours (EST/PST). We offer phone, email, and video call support. Any defective units are replaced immediately — we cover return shipping and replacement cost. Warranty: 24 months from shipment.
