Model J 3-Way Thermostatic Valve (¾" | DN20)

J Valve


AMOT Model J thermostatic valves, or thermal bypass valves, are fully automatic, 3-way fluid temperature controllers for diverting or mixing applications. They are used to provide reliable control of fluid temperatures in engine jacket water and lubricating oil systems. These valves are suitable for process control and industrial applications where fluids must be mixed or diverted depending on their temperatures. They may also be applied to cogeneration systems to control temperatures in the heat recovery loop assuring proper engine cooling and maximizing heat recovery. As with other AMOT thermostatic valves, the J valve uses fully enclosed, factory-set temperature element assemblies which provide tamper-proof operation.
