Schley T27 Overflow Valve

> Used in pump circuits to keep a certain pressure constant
> The sealing between the guide sleeve and the cone takes place with an O-ring

Overflow valve – T27

Self-operated, for liquids, gas, and steam
  • DN15 bis DN200 (½” bis 8”)
  • PN16- PN40
  • Set pressure: 0,5 – 40 bar
  • For liquids and gases
  • EN-JS1030, 1.0619, 1.4408, 1.4469,
    CC480K, CC333G

 

The overflow valve T27 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 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).

 

Efficiency Guardians

Overflowing tanks don’t just create messes; they waste precious resources. These valves ensure optimal filling levels, preventing costly spills and ensuring efficient use of your valuable fluids.
