Pneumatic diaphragm valve
This valve is specially used to control non corrosive or general corrosive medium, the inner surface of the valve body is not lined or covered with various rubber, which is suitable for different working temperature and fluid pipeline. Suitable temperature: less than or equal to 85 DEG C and less than or equal to 100 DEG C and less than or equal to 120 DEG C, C = 150 (according to the liner and diaphragm material)
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
