Since its birth it has dedicated itself to serve and respond to the needs of its customers, continuoulsy incorporationg new features. Constantly perfecting its products, using state of the art machinery, it is now a redesigned organization to comply with ISO 9001 standards, with a product engineering and market-designed orientation controlled by engineers and technical specialist that check all the manufacturing stages that have made JEFFERSON, not only a pioneers in Argentina, but a leader in the control of fluids.

Currently its catalog of standard products includes over 3,000 models between solenoid valves and magnetic level switches which satisfy different needs and industrial requirements to control the most diverse liquids and gases such as water, air, steam, oils, refrigerants, oxygen, liquid nitrogen, corrosive fluids and many others.

Its principal customers cover a wide spectre of world-wide industries like petroleum, engineering, laboratories, construction, fodd & beverage, heating, automobiles, metallurgical, textile, chemical & petrochemical etc.

Its products have international recognition as attested by the approvals of UNDERWRITERS LABORATORIES(UL) in the USA, CANADIAN STANDARDS ASSOCAITION(CSA) in Canada, amongst other, which has permiteed Jefferson to introduce its product range in direct competition with other market leaders in more than 22 countries covering the five continents in such competitive markets as the USA, Canada, Mexico, Brazil, Australia, Japan, Taiwan, Greece and recently, in closed countries such as Japan, Taiwan and Singapore, with special models. Jefferson's international insertion is reflected with the establishment in Brazil through JEFFERSON SOLENOIDBRAS LTDA., in Mexico through VALJEFF S.A. de C.V., in the USA through JEFFERSON SOLENOID VALVES U.SA. INC., with seat in Miami and sales offices in New York, from which they are taken care of U.S.A. market and Canada. In additiona a network of distributors in the rest of world, fulfill the objective to cover with sales and services in all the orb.

 

 

Valves for high pressure applications

There are a lot of applications with high pressure ranges where high-quality valves are required.

The GSR valves for high pressure applications are used, e. g., as pilot valve for actuators or as control valve in fire-fighting systems.

Further application areas are, e. g.: 

• paper processing industry
• steel production in blast furnaces
• gardening and cultivation technology
• water hydraulics
• pneumatic
• water installations on vessels
• high pressure pumps
• water and oil hydraulics 
• nitrogen applications
• press- and watergate control.

Especially for natural gas filling stations or hydrogen filling stations we recommend valve blocks which are also available as single valve, threefold valve block or sixfold valve block.

Please contact us. We will find the right solution for your application!

 

 

With more than 40 years` experience in custom-made valve solutions we developed a wide product range of solenoid valves and pressure controlled valves covering nearly all industries, mainly high pressure industries, high temperature industries, water technology and many more.

However, our main focus applies to custom-made valve solutions. Together with our customers we develop system solutions and engineer them.

The GSR engineers can select the suitable valve from our extensive add-on system. Furthermore, we have over 1000 valve options like sealed plunger, position indicator, control units, hand levers, etc..

Additionally, we are specialized in the development and production of valves for high pressure applications. In this special field we can look back on big know-how and experience. Our products are made of high-class materials and do have the latest block solutions for CNG and hydrogen.

All our solenoid valves, whether they are designed as pilot operated, force pilot operated or direct acting valves, are available with explosion proof according to ATEX.

Also for the North-American market our coils have the FM-approval and the UL-approval.

Offering you a complete choice of products which include cryogenic solenoid valve and cryogenic safety valves.

Our range of products include 1330 series by jefferson and ode 21z series pinch valve.

Solenoid valves for combustible gases:

1330 / 2030, 1332, 1388 and 2088 Series valves are especially designed to comply with the Resolutions, Regulations and Recommendations for the use of Natural Gas in Industrial Installations. They may be used with other gases, such as GLP, propane, manufactured gas, etc., as well as with air or any other noncombustible neutral gas. Maximum operating pressure for normally closed 1330/2030 series diaphragm valves, when applied as safety valves in natural gas burners, is 0.160 kg/cm2.

For normally open valves, it’s 0.5 kg/cm2  with regular diaphragm  and 2 kg/cm2 with reinforced diaphragm. 1330 / 2030 Series Normally Closed diaphragm valves are optionally provided with adjustable slow openings up to 10 sec.
 
1388 series valves include a system that allows them to open in two stages, the rst of which is quick and with
adjustable opening percentage, and the second is time adjustable up to > 20 seconds.

1330 / 2030, 1332, 1388 and 2088 Series are optionally provided with microcontacts for proof of closed valve.
2088 Series is provided with a power-rectier-controller that makes it possible for the valve to open at max. coil power, and after 90 sec. to come down to 16% of nominal value, that is, starting at 50 W and down to 8 W after 90 sec. The benets over conventional systems are, safe opening, low power consumption, low working temperature and longer coil life.

Our product range includes a wide range of 2/529 series by gsr.
