Pressure Relief valve

Thanner pressure relief valves OTS 65 are available for clamping only.

Thanner pressure relief valves OTS 45 are available for clamping and for flanges welded to the fabric. The flanges are available for welding to both PU and PVC.

The main parts of the valves are made from POM and the valve is made to enable replacement of a defect valve from outside, without damage of the buoyancy.

Due to the dynamic design of the valves, they produce a high flow rate in relation to their size. Closure caps, as a part of the valve, are available as an option.
