NEEDLE VALVES

More than 50 years working for your safety. We are experts in needle valves

Our needle valves

Needle valve valve with conic stem shutter to stable precision seal for use in general applications. Ideal for flow regulation, isolation, sealing and venting of liquids and gases systems.

Because of its stability, precision and shutter design makes easier metal sealing with really low watage avoiding cavitation at high differential pressures and is ideal for keeping instruments separate in order to protect them in maintenance and calibration Works.

The non rotative stem system with self-centering seat ensures perfect sealing.

CNC machining, test beds from 0.5 to 690 bar (7-10000 psi), allow us to manufacture high quality products with the guarantee of all our back ground.

NEEDLE VALVES USUAL APPLICATIONS

Needle valves for steam

There Are many applications in industrial processes steam and their main feature is to work under high pressure and high temperatures. Our process needle valves for steam cover the entire range of pressures and temperatures required for steam instrumentation. Up to 690 bar (0 to 10,000 psi) and from -200 to 500 ° C (-328 ° F to 932 ° F) Zaes needle valves for steam are a guarantee of safe for your steam facilities.

Needle valves for compressed air

Due to large number of industrial applications using compressed air, pressurized by industrial air compressors, there are lots of protective and measuring elements for such applications such as; mining equipment, packaging lines, material handling, medical compressed air, air compressors, etc.

ZAES Needle Valves guarantee full protection for measuring and control instruments in compressed air installations.

Needle valves for gas and cryogenics

For those applications that use fluids at the boiling point of nitrogen -195.79ºC (76.36º Kelvin) such as; transportation and liquid nitrogen storage and industrial gases, dilution refrigerators, cryogenic transfer lines, cryostats recuperators Helios, etc …

For this type and facilities ZAES cryogenic products as our needle valves, are designed to meet with warranty cryogenics service.

Needle valves for high pressure applications

Needle valves for high pressure Zaes reach values up to 690 bar (10,000 psi) with total guarantee maintaining the sealing capabilities and high pressure lines with measurement instrumentation.

Needle valves for petrochemical industry

Today oil is perhaps the most important power in the modern world.

From extraction to refining processes, Zaes makes available a wide range of commercial products for every related industries such as petrochemical storage and distribution of transportation fuels. Zaes Needle valves for fuel tanks cover the most demanding requirements of the fuel industry.
