1. There is no special requirement for general fluids. For requirements such as leakage, operating temperature and pressure, a straight-through single-seat control valve is available.
2. When the unbalanced force of the regulating valve is large and the pressure drop at both ends is large, the regulating valve with the balance hole valve core or sleeve should be used.
3, high viscosity, fluid containing suspended particles, optional angle control valve, ball valve, butterfly valve or eccentric rotary valve.
4, containing fiber materials, pulp and other fluids, V-shaped ball valve, gate valve can be selected.
5, corrosive medium fluid, corrosion-resistant materials should be used as the valve body and valve body parts, valve body separation valve, diaphragm valve and corrosion-resistant control valve with corrosion-resistant materials as the lining.
6, low pressure difference, large flow of gas fluid, optional butterfly valve.
7. When diverting or confluence is required, a three-way regulating valve can be selected. When the temperature difference between the two fluids is greater than 150 °C, two straight-through single seat valves or butterfly valves should be used.
8, high pressure drop and high static pressure applications, the use of high pressure regulating valve.
9. The sleeve valve is suitable for applications with clean fluids, free of particles and suspended solids, by selecting suitable trims or by means of noise reduction.
