Bei Verwendung des Nadeventils bei den Doppelmembranbaugrößen 1/2" und 1" wird die Gewindeverlängerung (5000-712) benötigt. Ein Doppel- oder Reduziernippel kann dabei nicht verwendet werden.
The needle valve regulates the air volume to Double diaphragm pump. In contrast to the ball valve, the air volume can be flexibly adjusted.

* The maximum flow rate is a value determined by means of a test bench and measured with water at a medium temperature of approx. 20 °C. The measurement is carried out at the pressure joint of the pump, without hose, nozzle or flow meter. The achievable flow rate in use is lower and depends on the individual application, the liquid properties and the configuration of the pump. The max. delivery head also depends on the pump design, motor and fluid. The viscosity values are determined with oil.
** Test assembly: Medium water / diesel, flow in preferred direction, settling section 0.2 m upstream and downstream of flow meter
