Highest quality butterfly valves

Manufactured in Milan, Italy, 3 different plants are used to manufacture and test Omal process valves, including their range of butterfly vales. The latest manufacturing technologies used allow maximum manufacturing control in the various production processes. It also means that Omal can quickly react to developing market needs.

The technologies are housed in 6 distinct areas, all contriving to result in consistent quality process valves, including butterfly valves. These areas are divided into foundry, painting-plant, CNC centre, plastics injection, assembly, laboratories and quality.

Butterfly valve applications

Corrosion-resistance, ATEX-compliance and couplings for every drive-type means that Omal butterfly valves from Hytec achieve extremely high performance in numerous applications across sub-Saharan Africa.

Butterfly valves are used the chemical, petrochemical & biogas industries; as well as water and wastewater, textile, steel works, oil & gas, marine, mining, food & beverage; automotive; and energy and power generation. These valves are also used on modular skids for gas mixing in blast furnaces.

Highest safety and environmental standards compliance

Omal butterfly valves are certified to the following performance, safety and environmental standards:

  • ISO 14001 (Environmental Management Systems)
  • ISO 9001 (Quality Management Systems)
  • ATEX Directive for use in potential explosive environments
  • GAS distribution systems in accordance with EN 13774
  • Directive 97/23/EC - PED (Pressure Equipment Directive)
  • SIL determinations

All butterfly valves and other process valves are designed with exceptional attention to detail and advanced manufacturing technologies. This allows Omal, and Tectra Automation as distributor, to provide valves for precise operation and with guaranteed quality, reliability and efficiency in your operation. They are manufactured to “Empower Performance”.

Additional information on butterfly valves from the Bosch Rexroth South Africa Group of Companies

Stainless Steel Butterfly Valves: Working temperature from 0° to 150° C and a working pressure of PN 6.

Lug Type Butterfly Valves: The shaft comes in 2 pieces which increases ease of disc maintenance and allows a high kV due to a central section of the disk being thinner than a valve with a single shaft.

Wafer Type Butterfly Valves: The valve disc circumference has a lapped surface, which provides better tightness and less wear of the liner. Lower friction reduces torque requirements.

Metal-Metal Type Butterfly Valves: Constructed with high-quality materials, like nickel-plated steel, spheroidal cast iron and aluminium paint.

PVC Butterfly Valves: Ideal for use with double acting actuators and, on the standard version, the body is constructed from reinforced polypropylene fibreglass, PVC-C butterfly and EPDM seal.
