WATERWORKS
SINCE THE BEGINING RACI SIGNS BEST PRODUCTS WITH RESEARCH AND QUALITY
RACI is an acronym, the literal translation in English is RESEARCH APPLICATIONS CHEMICAL INDUSTRAL: in our name is already enclosed our philosophy and our way of working.
The continuous RESEARCH of new solutions and APPLICATIONS is part of us and of our history, which began more than sixty years ago to industry and turned later to valves and accessories for water.
Raci introduced for the first time in Italy a long list of innovative products that today are standard in the water applications, such as the stainless steel repair clamps, the rubber wedge gate valves or the automatic control valves.
Today RACI continues to propose solutions and innovations for safe and reliable construction and maintenance of the waterworks, with a complete range of its own design and manufacture valves and accessories made to last, which are the result of well-established partnerships with the most selective private and public customers.
AUTOMATIC VALVESAUTOMATIC VALVES WITH HYDRAULIC OPERATION AND ELECTRONIC CONTROLS OF 3rd GENERATION
Clayton valves have got a native trait of innovation, so they were the first to look at the possibilities offered by electronic devices.
During a 15 year long research Clayton technicians and designers reach a level of development without equal.
Clayton valves didn’t lose the original hydraulic principle but now they are completed by a powerful, advanced and flexible electronic control system.
Following the ultimate trend of technology all devices for Clayton valves were designed to need the lowest power supply and to be potentially self-powered.
A COMPLETE RANGE OF SOLUTIONS TO INTEGRATE AND COMPLETE THE VALVES REGULATION:
MEASURE
Pressure sensors, flow meters and valve position transmitter can be inserted into the valve outlets.
CONTROL
An electronic controller IP68 manages and varies the command to the valve according to the input signals and the configured applications (ValvApps TM).
ACTUATION
The hydraulic action of the valve is changed by the intervention of solenoid valves or actuators
AUTONOMY
The electronic devices are designed to have the least power consumption. A complete and self-regulating system of production of electric energy makes the equipment completely autonomous.
VISIBILITY
The data transmission to a central SCADA system allows the user to view and continuously monitor the efficiency of regulation.
NEXT GENERATION OF CLAYTON VALVE: HYDRAULIC OPERATION VARIABLE AND INTERACTIVE
1. Pressure Management
This Clayton valve controls the pressure into the installation site and varies its action according to the effects in a farer point of the waterwork’s net.
The whole equipment is self powered and able to log and transmit all relevant data to a central SCADA system.
2. Dynamic districts
This Clayton valve is able to modify the topology of a waterwork’s district as well as control the flow according to time schedule.
The whole equipment is self powered and able to log and transmit all relevant data to a central SCADA system.
PIPELINE PROTECTIONThe protection of underground pipes involves us since the very beginning: Raci was founded in 1952 as the exclusive importer of Denso GmbH (Germany), the company that invented the first petrolatum-based coating for pipes and metal structures. A very simple product, able to immediately and permanently protect from corrosion, without requiring previous preparation of the surfaces.
Raci, after an “in parallel” market’s introduction of the bitumen tapes for corrosion prevention/protection, has then revolutionized the method of isolation of field joint welds for buried pipelines, until then carried out with the heating tarring method, quite difficult and dangerous for jobsite operators.
Over the years, the bitumen compound tapes were side by side and then replaced, by the butyl tapes, in both single tape mode and multi-layer systems, including the mechanical protection layer.
The advent of heat shrinkable sleeve systems has expanded RACI’s product range, applicable in a wide range of sizes, from the 1'' pipe for house connections, up to the larger diameters pipelines’ of water supply.
Raci has patented in the early 70s the first plastic tunnel system in polystyrene, to build methane feeder underground tunnels, which became the normative standard in Italy for the gas pipelines, for conveying possible gas losses into atmosphere.
Raci has patented in 1975 the casing spacers, an innovative modular system, able to preserve the carrier pipes’ isolation and grant relevant mechanical protection, in case they are placed into protection pipes (cased crossings). A state of art system for reliability and modularity, made entirely of plastic (high density polyethylene) and with no metal parts, which Raci has been successfully exporting around the world since then.
The new installation techniques, a.k.a. "no dig" crossings, nowadays require an improved mechanical protection of the particularly abrasion-resistant joints, during the insertion/drilling phase. Raci proposes an innovative coating system, made in glass fiber – reinforced polyester, which hardens itself just on UV rays exposure, without additional operations on site.
The RACI range of accessories for pipes ‘installation & maintenance, is completed with mechanical sealing systems for wall penetration pipelines, both modular or “fit to size”. These sealing elements, even in case of pipe’s movements in operation, ensure total sealing and leakage prevention.
In addition to the product lines for protection of pipes and relevant accessories, RACI has also a wide range of signaling tapes and tapes with net, for buried underground pipelines, and indicator signposts for aerial surveillance.
AUTOMATIC VALVESTHE BEGINNINGS THAT TRACE THE FUTURE
In 1978 Raci ltd company achieved the first agency fee in Europe from the American company Cla-Val whose founder was the creator of Clayton automatic valves patent. Introducing the concept of a diaphragm valve hydraulically actuated into pipelines service regulation he revolutionized the traditional systems for water transport and distribution.
During the years, Raci distributed more than 50.000 Clayton automatic valves in the Italian market, most part of them are still working today.
CLAYTON VALVES RANGE OFFERS TO THEIR USERS 80 YEARS OF EXPERIENCE
Using the same hydraulic principle, improved and applied to various functions, Clayton valves gave incisive and enduring solutions in Italy and around the world.
Even they have been copied in several versions, Clayton valves stay the equipment with the bigger presence on filed and with the larger range of models and customizations.
EXPERIENCE MEANS EXPERTIES AND PLENITUDE
Clayton valves catalogue offers numerous resources and various solutions for such any kind of needing in waterworks pipes net regulation and management.
These automatic valves control flow, pressure and reservoirs level in very reliable and accurate way. Often the principal function of a valve is combined with additional controls and adjustments or automatic reactions in order to realize an equipment that could match the specific characteristics of the system to which is intended.
Raci company, with its own history and by the Clayton catalogue, offers to waterworks companies and designers not only THE automatic valve, but also research and investigation of the best solution for any kind of regulation needs.
Shifting from the more simple to the ideal kind of water supply system, the Clayton automatic control valves can provide many different settings and solutions.
Our primary purpose is to combine the basic functions in order to suggest the most complete and performing equipment to solve the specific requirement on field.
Since more than 70 years on the market, today almost a symbol: RACI built his image of authority and credibility day by day, starting from the design office up to the realization of the venture. Synonymous of reliability and professionalism, RACI has become a reference: research, technology, professional updating and constant care service will allow it to always remain the same over time.
