SO.WELL pneumatic control valve

Adopting double-side structure and multi-spring actuating structure, the pneumatic diaphragm double-seat control valve features compact structure, light weight, flexible reaction, big valve capacity, accurate flow characteristics, easy dismounting and other advantages. The product has been widely used in accurate flow control of mediums like gas, liquid, steam, etc. with technical parameters such as pressure, flow rate, temperature and liquid level maintained in set value. It applies especially to non-clean mediums which allow bigger pressure difference and bigger leakage rate. This series product is specified by standard, bellow seal, jacket insulation and other models. Nominal pressure level: PN10, 16, 40, 64; Valve diameter range: DN20-200. Flow temperature applied: -200-+560, several levels are available within the range. Leakage rate standard: level II or level IV. Flow characteristics: linearity or equal-percentage.
