Description
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 double-acting rotary PA-DA are designed to automate the process of controlling industrial valves with a maximum torque of up to 2128 Nm.
The limit switch unit is designed for visual and electrical signaling of the end positions of the shut-off element of the valve: valve, tap or butterfly valve. It is installed on top of the surface of the pneumatic drive and connected to the DIN standard drive shaft. In a sealed box, as a rule, there are two sensors that monitor the position of the drive shaft and signal in extreme positions. OMRON microswitches, inductive sensors or reed switches are used as sensors. Visual indication of the position can be seen on the body of the unit there is a 3D visual indicator RED - CLOSED and GREEN - OPEN.
