Kuhnke 47.260 Pneumatic Non-return Valve.
Non-return valves allow air to flow in one direction only. Pilot pressure is applied to port 1 of the valve which shifts the spring and ball mechanism so that air can pass through. Upon removal of pilot pressure to port 1, back pressure from port 2 pushes against the ball and spring mechanism stopping air from passing back through to port 1.
The Kuhnke 47.260 non-return valve is constructed of brass, the port size is M5 female threaded. An arrow on the valve shows the direction of flow.
