Description
Ball valves are used as shut-off valves in heat and 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. The use of ball valves as regulating valves is not allowed.
The electro-pneumatic rotary positioner is used to control pneumatic rotary actuators using an electric controller or a control system with an analog DC output signal with a range of 4 to 20 mA.
Pneumatic DNOVA pneumatic double-acting rotary actuators PADA are designed to automate the process of controlling industrial valves with maximum torque up to 2128 Nm.
The manual doubler with worm gear and reduction reducer allows to manually set the required positioning of the shut-off valve by a quarter turn, acting as an alternative to pneumatic, electric or hydraulic quarter-turn actuators. Suitable for both indoor and outdoor installation. The modular design of the manual doubler is designed to provide the most effective and efficient solution to the full range of manual override applications.
