(20mm check valve)
The 20mm check valve
serves as a critical component in preventing backflow across industrial pipelines. Engineered for DN20 (3/4") systems operating at 16-25 bar, these valves demonstrate 99.6% leak prevention efficiency in third-party ISO 5208 tests. Leading check valve 20mm factories now integrate hardened stainless steel seats (HRC 58-62) to withstand 15,000+ duty cycles without failure.
Modern 20mm check valves incorporate computational fluid dynamics (CFD)-optimized discs that reduce pressure drop by 42% compared to traditional models. Dual-seal configurations combining PTFE and metal-to-metal contact achieve zero-leak certification per API 598. Our production facility's automated assembly line maintains ±0.02mm dimensional accuracy across 20,000 monthly units.

A: A 20mm check valve typically has a 20mm (3/4") diameter, operates at pressures up to 16 bar, and is designed for unidirectional flow control. Materials like brass, stainless steel, or PVC are common, depending on the application.
A: Ensure the supplier provides certifications like ISO 9001, product test reports, and compliance with industry standards. Reputable check valve 20mm suppliers often offer warranties and have verified customer reviews.
A: Yes, many factories offer customization, including material choices, pressure ratings, or connection types (threaded, flanged). Provide your requirements to the check valve 20mm factory for tailored solutions.
A: Leading check valve 20mm exporters supply globally, with strong markets in Europe, North America, Asia, and the Middle East. They often comply with regional standards like ANSI, DIN, or JIS.
A: Standard orders from a check valve 20mm factory take 7-15 days, depending on stock availability. Bulk or custom orders may require 3-6 weeks for production and quality checks.
