Overflow valve – T27F
Self-operated, for liquids, gas, and steam
- DN15 to DN200 (1/2“ bis 8“)
- PN16 to PN40
- Outlet pressure: 0,5–40 bar
- With stainless steel bellow 1.4571
- For liquids, gases and steam

The overflow valve T27F is a single-seat valve and is especially suitable for incompressible media, for example, water, oil (lubrication oil, fuel oil, HFO, LFO, MGO), etc. The valves are fully relieved so that the back pressure has no effect on the set (overflow) pressure, only the flow quantity changes according to the pressure difference.

The function of overflow valves (relief valves, pressure retaining valves) is, that the outflow of the medium at a set pressure, in which an existing back pressure or vacuum does not affect the set overpressure (retaining pressure). The above-listed items are characteristic of an upstream pressure regulator, by comparison to a normal safety valve. The safety valve is only a device to prevent a specific pressure from being exceeded (set pressure).
Pressure Tamers
When pressure builds within your system, it’s not just the gauge needle that jumps. Overflow valves act as pressure relief valves, automatically opening at preset thresholds to safely vent excess pressure and maintain system stability.
