2、 Description of single seat regulating valve of inlet pneumatic:
The pneumatic single seat regulating valve imported by de lock in Germany is composed of de lock pneumatic multi spring film actuator and low flow resistance single seat valve, The compressed air is used as the power source, the pneumatic multi spring film actuator is used as the actuator, and the valve is driven by the accessories of the electrical valve positioner, converter solenoid valve and holding valve to realize the switch quantity or proportional adjustment. The control signal of 4-20mA milliampere or 0-10V V of industrial automation control system is received to complete the regulation of the pipeline medium: flow, pressure, temperature, etc Various process parameters. The single seat pneumatic regulating valve is low in height, light in weight, simple in equipment, compact in structure and smooth in flow passage, and has a large flow coefficient. It is suitable for the occasions where the leakage is strict, the pressure difference between the front and rear of the valve is low and has certain viscosity. It is widely used in the electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries.
