The K44 In-line cylinder valve is engineered for higher airflow capacity and increased robustness. It is a highly durable valve designed for breathing air cylinders used by firefighters in demanding operational environments. Its in-line handwheel is positioned opposite to the cylinder connection and provides intuitive handling, even when wearing gloves or operating under stress.

The valve combines proven mechanical reliability with certified safety performance, making it ideal for SCBA systems in fire and rescue operations. An O‑ring sealing system with a rotating spindle ensures a smooth and tight closure.

It is available with several safety-enhancing options:

• Ratchet handwheel to prevent unintentional closing
• Push‑button handwheel variants
• Double winged handwheel
• Excess Flow Valve (EFV) to limit airflow in case of accidental damage
• Burst disc for controlled overpressure relief
• Pressure gauge
