The gate valve type 4004 with exhaust unit is used for retrofits or new construction of PE gas pipes in the pressure range ≤ PN 4.
Type
- identical with the 4004 series
- as molded parts, the PE pipe ends for welding are extruded and mechanically processed. They are mounted tendion-free and friction-locked as plug-in connection in the TYTON®-socket. Locking and pull-out protection is ensured through a thrust resisting joint locking ring on the outside
- the length ot the PE pipes section enables double socket welding. The PE pipes are available pursuant to DIN 8074 in SDR 11 and, alternatively in SDR 17
- the exhaust pipes are welded on the casing with steel pipes until the first ball valve is reached (DN80 - 200 = 11")
- the height depends on the pipe coverage or the customer's request. One ball valve each is welded to the upper end of the blow out valves down to the shut-off position. Both blow-out pipes are locked with the Düker gate valve by means of a tripe clamp via the installation set
