Wenzhou what type pneumatic control valve?

Wenzhou what type pneumatic control valve? Pneumatic control valve is used in many industries, but the largest number of use, industrial automation, by accepting conditioning control unit of the output control signal, from engine operation to change the medium flow rate, pressure, temperature, liquid level of the process parameters such as the final control element. And valve general, the executing agency. Wenzhou what type pneumatic control valve? Pneumatic control valve of the valve body is a lot of more phyletic, the commonly used types of the body is through single-seat, direct two-seater, angular, diaphragm, small flow rate, tee, eccentric rotating, butterfly, sleeve, spherical, etc. In specific choices, to do the following: 1, the shape of the valve core structure mainly based on the selected flow characteristic and factors such as unbalanced force. 2, when the fluid is suspending liquid containing high concentrations of wear particles, the interior of the valve material is hard. 3, corrosion resistance due to the corrosive medium, to choose structure simple valves. 4, medium temperature, pressure, when the medium temperature, high pressure and large, should choose the valve core and valve seat materials by temperature, pressure changes small valves, when the temperature 250 ℃ or higher should add the radiator. 5, flash and cavitation in liquid medium. In actual production process, flash and cavitation will form the vibration and noise, shorten the service life of the valve, therefore when selecting valves should prevent the valve from flash and cavitation.
