The CV03 Inline Check Valve (Non-Return Valve) is engineered to maintain unidirectional flow and prevent reverse flow in medium-to-high flow pneumatic systems. Designed with 3/8" Female PT / NPT / BSPT thread ports on both ends, it provides an airtight inline barrier for compressed air circuits, air distribution manifolds, and industrial machinery.
Constructed with a durable nickel-plated brass body and a spring-loaded internal mechanism with NBR rubber seals, the CV03 delivers quick shutoff when backpressure occurs. Its corrosion-resistant build prevents system pressure drops and protects sensitive upstream equipment against backflow.
