Model RO Thermostatic Control Valve

The AMOT Model R(O) thermostatic control valve provides reliable control of fluid temperatures in cooling systems, heat recovery and many other temperature control applications. The model R control valve is also suitable for process control and industrial applications where fluids must be mixed or diverted depending upon temperature.

All AMOT internally sensed valves have positive 3-way action. This ensures that all of the flow is through the bypass line giving the fastest possible warm-up time on process start-up.

Operation and flow control is established by the temperature element, which constantly monitors and regulates the process fluid to the exact specified temperature setting. When required, the valve will positively shut off the bypass line to give complete cooling.

A 3-way valve ensures constant volume flow in the system and gives no restriction during the warm up cycle, ensuring maximum performance. Where shut off is not required, bypass holes are available. The temperature control power is created by the expansion of a wax/copper mixture which is highly sensitive to temperature changes.

Large forces are created by the warming/expansion of the mixture, which in turn acts upon the sliding valve, thus regulating the flow.

The diagram opposite shows the valve actuation in diverting mode at start and cooling positions. During operation, the sliding valve constantly modulates for accurate temperature control.

The reliable, rugged construction provides a unit sensitive to temperature variations, not easily disturbed by pressure changes and sudden surges, which maintains stable temperatures over a wide range of operating conditions.
