  • Valves and flow equipment for thermal oil systems
    Valves and flow equipment for thermal oil systems
    Posted in: Markets

    Thermal oil systems are used in industrial processes where heat transfer is required at high temperatures with lower operating pressure compared with equivalent steam systems. Thermal oil circulates in a closed loop and supplies heat exchangers, reactors, presses, dryers, tanks, moulds and thermal process units. Valves in thermal oil networks are selected according to operating temperature, pressure, fluid viscosity, circulation rate, differential pressure and sealing requirements....

    Valves and flow equipment for the refrigeration industry
    Posted in: Markets

    Industrial refrigeration installations operate with refrigerant, glycol, chilled water, condenser water, compressed air and auxiliary service circuits. Valves in these systems are selected according to operating temperature, pressure, fluid type, differential pressure, operating frequency and sealing requirements. Cold rooms, food processing plants, refrigeration units, heat exchangers, condensers, evaporators and distribution networks require controlled flow and stable operation. Correct...

  • Valves and flow equipment for hydrogen applications
    Valves and flow equipment for hydrogen applications
    Posted in: Markets

    Hydrogen systems require valves and flow equipment with suitable tightness, material compatibility and operating capability for the pressure and temperature range of the installation. Due to its small molecular size, hydrogen can have an increased tendency to escape through connections, gaskets, packing and stem sealing points. Hydrogen production, compression, storage, distribution and utilisation units require flow control in main and auxiliary lines. Valve selection is based on operating...

  • Valves and flow equipment for the organic chemicals industry
    Valves and flow equipment for the organic chemicals industry
    Posted in: Markets

    Organic chemical plants operate with solvent, organic intermediate, resin, alcohol, hydrocarbon, additive, petrochemical product, steam, thermal oil, chilled water, glycol, nitrogen, compressed air and auxiliary fluid lines. Valve selection is based on fluid chemistry, temperature, pressure, viscosity, volatility, flammability and the sealing requirements of each line. Organic synthesis, mixing, distillation, condensation, storage, transfer and dosing processes require a defined function for...

  • Valves and flow equipment for alcohol lines
    Valves and flow equipment for alcohol lines
    Posted in: Markets

    Alcohols are used in chemical, pharmaceutical, energy, cosmetics and industrial plants as solvents, raw materials, intermediates, cleaning media or mixture components. In methanol, ethanol, propanol, butanol, glycol and other alcohol lines, valve selection is based on chemical compatibility, pressure, temperature, volatility, viscosity, flammability and sealing requirements. Alcohols may be handled in storage, transfer, mixing, dosing, heating, cooling, distillation and recovery lines....
