Duker - Model 1004 - Tapping Valve - Brochure

TOP is the valve for upper tapping. TOPsi is the counterpart for lateral tapping. Both can be fitted to pipelines made of cast iron, steel or fibre cement. Thanks to different stainless steel clapping bands, TOP and TOPsi are suitable for pipes from DN 80 to DN 300. The tapping can be done under pressure with the help of a standard tapping device after screwing on the valve. The outlet is either an internal thread (Rp 1¼, 1½ or 2) or, in the case of the TOP model, a PE connection (PE 100 SDR 11 in DN 25, 32, 40 or 50).
