CV04 Pneumatic Inline Check Valve / One-Way Non-Return Air Valve 1/2" Female Thread
The CV04 Inline Check Valve (Non-Return Valve) is built for high-flow pneumatic and fluid setups where strict unidirectional flow control is essential. Featuring 1/2" Female PT / NPT / BSPT thread ports on both ends, it provides an airtight, full-flow inline barrier to prevent backflow in large-diameter air lines, compressor discharges, and industrial automation systems.
Constructed with a heavy-duty nickel-plated brass body and a precision spring-loaded internal core, the CV04 ensures immediate shutoff when reverse pressure is detected. Its robust structure provides high pressure resistance, reliable long-term performance, and excellent protection for upstream air equipment.
