Aunspach Controls' Models D86 & D80 prevent water and wastewater valve damage caused by excessive operating torque.
Aunspach Controls’ Models D86 & D80 prevent water and wastewater valve damage caused by excessive operating torque. Operator safety is enhanced, valve damage and possible system downtime are avoided. Model D80 protects handwheel-actuated valves and is mounted between the handwheel and actuator. Model D86 protects AWWA nut-actuated valves and is mounted on the valve operating nut. Both models transmit operating torque but stop damaging torque. No maintenance is required. The mechanisms are permanently lubricated and hermetically sealed to exceed IP68 water ingress standard. Units are shipped pre-calibrated and ready to mount.
