Descaling Valves Size Dn 63-250 (2.5”-10”)
| Schrupp
descaling valves are 2 way cartridge type valves especially designed to
withstand the high pressures and levels of contamination found in typical
steel mill descaling systems. Schrupp
valves are operating worldwide in continuous duty processes with excellent
results.
The
Schrupp cartridge design is extremely maintenance friendly.
The poppet, sleeve, and seat are completely manufactured out of
stainless steel. The use of a
soft seal in the seat area allows complete repair of the valve without the
necessity of any machining procedures. |

Schrupp
Descaling Valves Type 1
These valves are
electro-pneumatically piloted and can be used for leak free operation.
The robust construction is designed for long service life and
safety even in the harsh environment of typical steel mill descaling
systems. This design can also
be used for accumulator safety functions or as a pilot operated check
valve when pilot pressure is taken from the B port.

Schrupp Descaling Valves Type 2
| These
valves are electro-pneumatically piloted, cylinder operated, with
individually adjustable opening and closing speed.
This design is particularly effective in descaling systems with
higher levels of contamination and does not require a pilot filtration
system. The robust
construction is designed for long service life and safety even in the
harsh environment of the typical steel mill descaling system. |

| Schrupp Descaling Valve Type 3 |
|
| These
valves are electro-hydraulically pilot operated. The direct operated solenoid valves control two size DN25
pilot cartridges which control pilot flow into and out of the main
cartridge pilot area. The
pilot medium can be water, oil, or filtered operating system medium.
The opening and closing times are independently adjustable.
The robust construction is designed for long service life and
safety even in the harsh environment of the typical steel mill descaling
system. |
