ROSoV / Pneumatic On-Off Valves
ROSoV (Remotely Operated Shutoff Valves) are specially designed valves used for rapid isolation of critical plant equipment handling hazardous fluids and gases. These valves play a vital role in industrial safety systems by ensuring immediate shutdown during emergency situations, helping prevent leakage, fire hazards, and operational damage.
Also known as Emergency Isolation Valves (EIV) or Emergency Shutdown Valves (ESDV), ROSoV valves are widely used in tank farms, oil & gas plants, chemical industries, refineries, and process industries. These pneumatically actuated butterfly valves are equipped with fail-safe actuators that automatically move the valve to a safe position during power or air failure, ensuring maximum plant protection.
Pneumatic On-Off valves are designed to operate in either a fully open or fully closed position. They are ideal for applications requiring quick and reliable shutoff performance. These valves can be integrated with several advanced accessories such as Solenoid Valves, Air Filter Regulators, Limit Switches, Positioners, MODBUS Serial Communication, Foundation Fieldbus, and Profibus systems for efficient automation and remote monitoring.
Available in sizes ranging from 2” to 100” and pressure ratings up to ANSI Class #900, these valves are suitable for a wide range of industrial operations. Their simple design, fast response time, low maintenance, and cost-effective operation make pneumatically actuated butterfly valves a preferred choice across industries.
Advance Valves offers high-quality ROSoV and Pneumatic On-Off Valve solutions engineered for durability, safety, and dependable performance in demanding industrial environments.
