Sub Sea Valves:

Valves designed according to international and national standards for subsea applications, withstanding external pressure corresponding to a water column of 3,400 meters. We offer special features and different types of construction to meet customer needs, including welded “Fully Eelded”, bolted body, Top Entry, soft or metal seats, triple seal shaft, among others. We perform hyperbaric tests according to customer specifications.

Abrasive fluid valves:

For fluids containing solid particles, we supply ball valves with Tungsten Carbide (WC) coated ball and seats to prevent erosion of the sealing surfaces.

Valves for high temperature application:

We offer valves designed to operate at elevated temperatures, ensuring sealing class within specified limits. These valves have an extended body recommended for temperatures above 250°C, in addition to trim and seals suitable for operation at high temperatures. We also use Tungsten Carbide (WC) or Chromium Carbide (CrC) coated metal balls and seats when soft seats are not recommended.

Valves for high “very high” pressure application:

We have developed trunnion ball valves capable of withstanding very high pressures, in accordance with API 6A Class 2000 to 20000 and ASME B16.34 Class 4500 standards. We are experienced in carrying out special tests in accordance with API 6A standard.

Valves for Cryogenic services - Low Temperature:

Valves suitable for operating in low temperature fluid treatment processes, ensuring sealing classes within specific limits.

Valves for service in acidic environment and fluid (API 6D, 7.7):

For environments containing H2S in oil and gas production, we supply valves with materials that meet ISO 15156 (NACE) requirements. We can provide HIC and SSCC corrosion test certificates upon request.

Valves for corrosive environment service:

We offer valves with alloy steel, Nickel alloy, Duplex (22Cr – 2 Ni) and Superduplex (25 Cr – 5 Ni) according to the corrosion resistance requirements established in special standards, such as Norsok MDS D46 and D44 for Duplex, D56 and D54 for Superduplex, among others. We use techniques like nickel.

Valves for reduced fugitive emission:

Often, ball valves are ordered with “reduced emission”, meeting regulations that establish low emission rates to the atmosphere. In that case, we supply a special type of valve with a high quality surface finish on the body and shaft surfaces, as well as appropriate seals.

Valves for explosive decompression:

To eliminate the possibility of O-ring explosion due to rapid decompression of gas absorbed by the molecular structure of the elastomeric sealing element, we employ valves with O-rings or sealing washers resistant to explosive decompression.

Valves for Carbon Dioxide, Chlorine, Oxygen fluids:

Valves that work with special fluids must meet specific requirements, according to procedures determined by the plant and manufacturer. To avoid the risk of explosive decompression when using carbon dioxide, we use special O-rings and sealing washers. Valves employed with chlorine require special features, including complete grease lubrication and decontamination. Valves used with oxygen, on the other hand, require special features to eliminate the risk of ignition.
