China Stainless Steel Pneumatic Butterfly Valve

High quality stainless steel pneumatic butterfly valve

Products Description
Pneumatic regulating butterfly valve is an adjustable pneumatic net that uses the air source to adjust the opening of the butterfly plate to control the flow rate of the medium. Pieces matching combination. The pneumatic regulating valve adjusts the opening degree of the valve through 0.4-0.7MPa intake air after inputting 4-20MA signal according to the valve positioner in the automation system, so as to achieve The proportional precise adjustment of the process parameters such as medium flow, pressure, temperature and liquid level in the pipeline is the best device for adjusting the flow and carrying fluid. Pneumatic regulating butterfly valve can choose different seals (soft seal and hard seal) according to the working conditions to meet different requirements. It is widely used in chemical, environmental protection, air, water, gas, steam and pipes containing corrosive media

Function / Operation Test
:At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.
Special Test
On request, any other test can be carried out according to special instruction by client.
