Unidelta Check Valve

The Unidelta Check Valve is a high-quality, non-return valve designed to ensure one-directional water flow in polyethylene (PE) pipe systems. Manufactured in Italy from premium, UV-resistant polypropylene with corrosion-proof internal components, this valve provides long-lasting performance and dependable protection for irrigation, plumbing, and potable water networks.

Featuring an integrated compression connection, the Unidelta Check Valve offers quick, secure, and leak-free installation without the need for special tools, heat welding, or adhesives. Its internal spring-loaded or swing-check mechanism (depending on model) prevents backflow, safeguards pumps and system components, and maintains system hygiene by preventing contamination.

Durable, easy to install, and engineered for consistent performance, the Unidelta Check Valve is an essential component for maintaining safety and reliability in pressurised PE pipeline systems.
