Simple Overriding Release Mechanism
The Marotta SPV82 Series Quick Closing Valve boasts a simple overriding release mechanism which provides emergency closing/opening in milliseconds. During normal operating conditions, these quick closing valves are actuated by the conventional hand wheel method. When an emergency occurs, a lever actuates the “armed” release mechanism, thus the valve is closed or opened without manually turning the hand wheel. This emergency operation can be local or remote through the use of a cable. Operational methods for actuating the quick release mechanism can be electrical or pressure operated.
