Couplings Designed For Every Industry
Since 1951, German based company, WALTHER-PRÄZISION, has developed and manufactured mono and multicouplings that are used wherever fluids, vapors, gases, electrical and optical signals as well as electric power need to be safely transferred. Their engineers develop solutions for almost every industry that meet highest demands, prove their value in extreme ambient conditions and help to protect the environment.
Walther Prazision is a “full-range supplier” of quick couplings and systems for all industries.
Nominal sizes of our couplings extend from 2 to 300 mm, with pressure ranges from vacuum to 3,000 bar.

Multi couplings, docking systems and fast and very slim tool changers for industrial robots to be used in shell constructions, transfer lines, manufacturing lines and test stations.
|CHEMICAL AND PHARMACEUTICAL|
Quick couplings made of stainless steel or other high quality materials, with non-dripping clean-break technology, available in non-interchangeable designs or as a breakaway coupling with no sacrificial parts, suitable for the safe connection of hazardous media lines.
|AEROSPACE AND AVIATION|
Docking systems designed to handle high stresses and quick couplings made of stainless steel, titanium or other high quality materials for efficient utilization of cost-intensive test benches, for the use in aircraft engines or for media supply in launch vehicles.
|MACHINE AND SYSTEMS ENGINEERING|
Reliable operation, clean-break quick couplings for liquids (hydraulic oil, grease, etc.) as well as numerous special quick coupling solutions in a proven, robust design and durable, even under the toughest operating conditions.
Plug and screw couplings have been developed for the medical sector, specifically for the medical gas supply, diagnostics, dialysis, computer tomography, sterile technology and the supply of breathing air.
|OFFSHORE AND SUBSEA|
Corrosion-resistant quick couplings and multi-couplings of user specified stainless steel with redundant sealing systems, power enhanced locks, also for the operation by divers or by remotely operated vehicles (ROV) for a quick and reliable connection of single lines and multiline umbilicals both top-side and subsea.
Robust quick couplings supply heavy equipment within the steel industry with hydraulics, pressurized air and other media. They are i. a. used to dock casting ladles, in thin-slab and continuous casting lines, at roll stands as well as in the automatic gas supply for batch furnaces.
Quick couplings which are used in transportation, must ensure a safe connection during permanent vibrations and in heavily soiled environment – for many years to go and under extreme temperature fluctuations.
Mono CouplingsWith quick couplings (or mono-couplings) a repeated quick and safe connection and disconnection of single fluidic or electric lines is simple and possible without additional use of tools. Besides the wide variety of our standard program of quick couplings with many materials and sealing qualities, we also offer specific individual solutions to our customers.

High Pressure CouplingsHigh pressure couplings are designed for nominal pressures up to 2,000 bar / 29,000 psi. Many options are available to increase performance and provide added safety. For large nominal bores, ring grips are recommended for ease of operation.
Clean Break CouplingsClean-break couplings are also called dry couplings according to the area of application and industry. They couple almost without any air or media entry; when disconnecting, there is only minimal leakage.

Offshore TechnologyRequirements of Couplings for Offshore Application
Long service life, extreme corrosion resistance and simple handling under adverse conditions – these are just some of the demands made on quick coupling systems by the offshore industry. Furthermore, the design of couplings for underwater application must be suitable for handling by divers or ROV manipulators.

Multi Coupling/Docking SystemDocking systems are automatic multi-couplings which can be perfectly involved in controlled processes. Due to integrated sensor technology, a docking system can transfer precise information about the position or the condition of the coupling halves to a superior control system.
