CPCVF pneumatic check valve is an in‑line one‑way valve with thread‑to‑quick‑fitting integrated design. It allows compressed air to pass in one direction and blocks reverse airflow. Widely applied for pressure retention, back‑flow prevention and vacuum holding in pneumatic circuits. Compatible with PU and nylon air tubes for cylinders, vacuum suction cups and automation pipelines. Nickel‑plated brass body with NBR sealing ensures compact size and easy installation, good interchangeability for imported counterparts.

CPCVF Pneumatic Check Valve

• Reliable one‑way sealing, near‑zero reverse leakage to protect pneumatic components from back‑pressure damage.
• Low cracking pressure, sensitive response, works steadily under low‑pressure and vacuum condition down to ‑100kPa.
• Thread‑quick‑plug integrated design for fast piping, saves assembly time for compact layout.
• Nickel‑plated brass housing plus durable NBR seal, anti‑rust and anti‑aging, working temperature 0‑60℃, long service life for continuous industrial operation.
• Mini‑compact structure, multiple sizes available, good interchangeability, lowers spare‑part cost.
• Versatile for cylinder circuits, vacuum grippers, jigs and fixtures, prevents sudden pressure loss after air supply cut‑off.
