The erosion resistant dosing control valves from Mitech fit in the main ring and are ideally suited for pH control by lime slurry dosing. They have an anti-clogging design and are trim sized to suit process data. The valves are rated for 600 kPa and their outlet port is designed to match the trim size. With an option of 'on/off' or modulating control, the valves have a nylon-coated cylinder with a double-acting or spring-return mechanism. Various options are available including pneumatic/electro-pneumatic positioners, solenoid valves, limit switches, position indication, handwheel override and stellite, ceramic or carbide trim.
