N.H.T. s.a. was founded in April of 1999 by Mr. Zoppi Nicola and by Mr. Santicioli Renato, the factory is placed in the Repubblica of San Marino, it's a little state completely independent inside the Italy territory. They have a plant of 600 sqm using automatic presses for plastic injection, and automatic machines for the mounting the float switch on the Quick-Stop valves. Their quality system allows a functioning test on 100% of their production. They are the only company in the world who are making this unique product, for which they have an International patent.

is part of the range of tank filling valves. It beats the traditional brass valves in terms of intervention rapidity, capacity, closure safety and compact dimensions. Its patented system allows it to dispose of large capacities (up to 9.2 cubic-m/h) in the entire delivery stage without any flow reduction. Providing ultra-fast closure feature in a fraction of a second, thereby eliminating the long and noisy throttled filling operations. A special internal profle prevents any dangerous water hammering during the closure stage.Thanks to this section QuickStop has also been able to pass the to stringent German tests (EN 50084 Nov.92).
The servo-assisted mechanism uses a snail Float as a control for the closure stage. Safety in this stage is in fact guaranteed by the actual pressure within the delivery pipe. QuickStop is available in the following versions: 3/8", 1/2", 3/4". 1", 1 1/2", 1 1/4", with BSP threading and in versions 3/4". I", I W\ 1 1/2" with American threading(all with entrance filter).The 3/4" and 1 1/2" versions are available with levers of two different lenghts of 300 mm or 320 mm. All the materials used are suitable for contact with food products and approved by the German DVGW standards body.
