Wachs Utility Products TM-7 safely implements AWWA valve exercising procedures on large valves, with the TM-7 fully conforming to the AWWA Valve Exercising Standard. Designed for stubborn valves, even ones you may already have scheduled for replacement, if it’s not broken the TM-7 will likely turn it. The TM-7 allows a single operator to exercise valves from 6in to 60in (DN150-1500) safely and quickly.
When a valve connected to steel or ductile iron pipe has not been exercised regularly, dirt, rust and sediment known as tuberculation builds up around the valve. This makes it difficult or impossible to manually operate it when the need arrives, which is especially true of larger or older valves often found in larger or more established cities. Worse, simply putting too much force on the valve trying to turn it can break the valve stem, leaving costly replacement as the only option.
Designed with a precision hydraulic drive system for torque control and direction of rotation, the TM-7 is equipped with an electronic revolution counter and an integral, auxiliary hydraulic circuit automatic cutoff triggered if user preset torque limits are reached. Its modular design features a powerful hydraulic motor and drive gear on a ball bearing, lockable slide that offers increased energy transfer and compact dimensions. The TM-7 allows a single operator to exercise valves from 6 to 60" (DN150-1500) safely and quickly.
