[. . . ] Suitable supply valves are the V5000 Kombi-3-plus RED or the V5100 Stop Valve-3 which are both compatible with the supply valve adapter of the V5012C Kombi-DP kit. The pressure of the supply pipeline is led to the Kombi-DP via the impulse tube and acts onto the top of the diaphragm, the pressure of the return pipeline is led to the Kombi-DP through the return valve and acts onto the bottom of the diaphragm. When the supply pressure increases, the diaphragm inside the Kombi-DP is pushed down against the return pressure. The diaphragm acts onto the insert of the connected return valve and the flow is throttled. When the supply pressure decreases, the diaphragm inside the Kombi-DP is pushed open by the return pressure. The diaphragm moves up, releasing the insert of the return valve and the flow increases. The desired differential pressure can be preset from 0. 1. . . 0. 3 or from 0. 3. . . 0. 6 bar, depending on the type used.
