ROSoV/ Pneumatic On Off

Remotely Operated Shutoff Valves (ROSoV) are valves designed and installed for the purpose of quickly isolating plant items which are used for the storage of hazardous substances.
These pneumatically actuated butterfly valves could also be called Emergency Isolation Valves (EIV) or Emergency Shutdown Valves (ESDV). A ROSoV VALVE with a Failsafe actuation for emergency Shutdown duties is a key safeguard for Tank Farm.
The On-Off valve along with a variety of accessories including Pneumatic actuators are used in the application where the valve is in fully open condition or fully closed condition. Advance Valves has the facility to provide the ON-OFF valve with a pneumatic actuator and MOV from a size range of 2" to 100" up to a class rating of ANSI #900. On-Off valves are majorly accessorized with Solenoid Valve, Air filter regulator, Limit switch, Positioners, MODBUS Serial / Foundation Fieldbus / Profibus etc.
The principal advantage of these pneumatically actuated butterfly valves is that they are cost-effective and that makes these options a little attractive.

FAQ's

A pneumatically actuated butterfly valve is a type of valve used to control the flow of liquids and gases. The actuator is operated by compressed air, which is used to open or close the valve. When the compressed air is applied to the actuator, it moves a piston or diaphragm that rotates the valve disk to the open or closed position. The actuator is designed to provide a high level of torque, making it ideal for applications where a large valve is required. The valve disk is positioned at an angle, allowing for precise control of the flow rate. Pneumatically actuated butterfly valves are commonly used in industries such as chemical, oil and gas, and water treatment, among others.

Actuated valves especially butterfly ones work by using an electric, hydraulic, or pneumatic actuator to control the opening and closing of the valve. The actuator is mounted on the valve stem and turns the disc within the valve body, either clockwise or counterclockwise, to regulate the flow of fluid or gas.

When the actuator receives a signal, it converts energy into motion, which rotates the valve disc to the desired position. Actuated butterfly valves are commonly used in industrial applications where a high degree of precision is required to control the flow of liquids or gases. They are known for their reliability, durability, and ability to handle high pressure and high temperatures.
