The ball valve is used as a shut-off valve in heat supply systems, water supply systems, in steam, fuel and pneumatic systems with compressed air and neutral gases. Installation of valves of this series is possible in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.), non-aggressive to the materials of the valve.
Pneumatic actuators DNOVA rotary with return spring PA-SA are designed to automate the process of controlling industrial valves with a maximum torque value of up to 2128 Nm.
Electro-pneumatic rotary positioner is used to control rotary type pneumatic actuators by means of electric controller or control system with analog DC output signal in the range of 4 to 20 mA.
