The Danfoss 061B7000 is an MBV 5000 test valve — a shut-off and test manifold that sits between the system and a pressure transmitter or pressure switch. It lets the transmitter be isolated, checked against a reference gauge and changed without draining or shutting down the plant, which is what makes it standard fitting on commercial refrigeration and air-conditioning pressure circuits where the alternative is pumping down the system to swap a sensor. This version has 1 inlet and 1 outlet, with a separate test function, so each line can be tested independently of the others. The test point takes a MiniMess coupling, which is included, so a gauge or datalogger can be connected under pressure without breaking into the circuit. Pressure connection is G 1/4 female to DIN 3852-E, and the outlet connection is flanged. Working pressure range is 0 bar to 120 bar (0 bar to 180 bar on oil). Ambient temperature range -20 °C to 120 °C. Manufacturer part number (code number) 061B7000.
