Ball valve DNOVA BV3131P(3pc)-FP-W-ISO-H LONG 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 BV3131P(3pc)-FP-W-ISO-H LONG series valves is possible in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.) that are not aggressive to valve materials.
Pneumatic actuator DNOVA PA-DA-105-1 of double action is designed for automation of control process of industrial shut-off valves - gates, ball valves. DNOVA pneumatic actuators are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
Pneumatic valve DNOVA 4V320-08 220V is used to change direction, start, stop compressed air flows in pneumatic system depending on external control action.
