A Rotelmann DN-4-S two-way manual ball valve with a DN4 nominal bore and M16x1.5 threaded ports. It is the small isolating valve used on hydraulic, lubrication, grease and pressure-gauge lines. A quarter turn takes it from full flow to shut, and in the open position the through-bore is straight, so it adds very little pressure drop to the line.
Rotelmann: German maker of small-bore ball valves and fittings for hydraulic and lubrication systems. DN 4: 4 mm nominal bore, which is the flow path rather than the thread. S: Rotelmann build and body variant designation. M16x1.5: metric port thread, the standard DIN 2353 light-series thread for 10 mm outside-diameter tube.
DN4 and M16x1.5 describe two different things. The bore governs flow; the thread governs what fitting or tube coupling screws in. A valve with the right thread and the wrong bore fits and still throttles the circuit.
Because it is a ball valve rather than a needle valve, it is an on/off device rather than a metering device. Partially opening a ball valve to trim flow wears the seat and gives no repeatable setting.
At DN4 this is characteristically a gauge isolator, test-point shut-off or a branch isolation on a lubrication manifold, where one small line is shut without draining the system.
Type: two-way manual ball valve, shut-off. Nominal bore: DN 4 (4 mm). Ports: M16x1.5 metric thread. Ports count: 2, straight through. Actuation: manual, quarter turn. Applications: hydraulic, lubrication and gauge lines. Origin: Germany.
Sold as one valve. The individual valves are loose rather than separately boxed. No fittings, tube couplings, adaptors or mounting hardware are included.
M16x1.5 is a parallel metric thread and seals on a cone or O-ring at the fitting rather than on the thread flanks. The handle requires clearance for a full quarter-turn swing.
Other DN sizes in the Rotelmann range use the same style of body with different bores and port threads, related sizes rather than substitutes. A replacement has to match both the DN bore and the M16x1.5 port thread.
