Safety First! Never forget to close a valve again! MAS G-2DM & CSCR-2DM Dead Man Handle Valves offer the highest level of protection from unwanted leakage and spills. The Dead Man design spring activated handle quickly closes when the manual torque of the valve operator is eliminated. In the event of a human operator lapse, the energized spring slams into action, quickly closing the valve and eliminating any unnecessary leakage. For high temperature and steam application, look to the MAS G-2-250 & CSCR-2-250 for the best sealing solutions.
