Valve testing without shut down

Stroke-Test device allows testing of critical valves without shutting down the process flow. It does not interrupt the revenue stream and ensures plant operators comply with industry safety standards. System operates on the “valve partial stroke testing” principle, which allows a safety system to close a valve only partially. When the device is fitted to a valve, it limits the movement of the actuator to within pre-set travel limits—for example, 20 deg. All valve control elements, such as solenoids, positioners, and relays, can be tested without the valve having to fully close. This wholly mechanical device does not need to be integrated into the control loop, and is vibration resistant, corrosion protected, and certified to IP67 to prevent water ingress. www.smithflowcontrol.com
