The Albatec VS-200 Series provides spring-driven emergency closure of high-pressure gas-cylinder valves. The cylinder valve is opened manually, and pneumatic pressure holds the shutter mechanism in its set position. When the control pressure is released, the spring mechanism automatically closes the cylinder valve. No electrical power supply is required at the device. Two torque versions are available for different cylinder-valve requirements: the standard VS-200 and the high-torque VS-200H2. Key features:
