Put static seal into the base that already had soldered, twist tailor-made ball valve again, notice impaction static seal, prevent slack. starting a hole implement the threaded coupling outside sealed jacket and ball valve. After screwing, open ball valve, till be contacted with the wall outside conduit,drive drill pipe, receive hand electric drill and drill pipe good locking, receive electrify source, begin bore. In bore process electric drill maintains low speed, rotate speed does not pass fast, lest jamming of a drilling tool, even broach breaks off. Get after appearing, pull out drill pipe till starting a hole implement the foremost end of broach is retreated to ball valve core hind, close ball valve, debus starting a hole implement. Attention: 1.
Power of conduit internal pressure defines above all before starting a hole, exceed 1 when conduit pressure.
When 0MPa, installation needs discreet, exceed 1 when conduit pressure.
When 6MPa, do not install, contact with manufacturer please, lest produce risk. 2.
Electric drill must make sure when the job borer and conduit are perpendicular, lest bore appears deviation, in bore process electric drill maintains low speed rotate speed not to want too fast, lest jamming of a drilling tool. CNC Milling
