Heater valve HSDHTRVLV

The Parker heater valve provides a small heating circuit flow to remote areas of a hydraulic system when the system temperature in that area drops below the desired temperature, while ensuring devices in the system receive flow priority. In the far extremities of a hydraulic system, the fluid can become stagnant and cold because of infrequent flow use by devices in that - hydraulic branch. The cold fluid results in reduced performance for these devices when they are eventually called upon to perform. - An example of this would be the hydraulic actuators for the outer ailerons providing sluggish response to the pilots during high-altitude - cruise. However, Parker's heater valve helps maintain warm hydraulic fluid is available for all devices on the system, ensuring they can - operate at peak performance at all times. - Parker Aerospace's heater valve monitors the fluid temperature at the extremities of these hydraulic system branches. When the temperature - drops below the ideal threshold, a small controlled stream of cold fluid is passed through a heating orifice and sent back through the system- - return lines to the hydraulic reservoir. This allows warm fluid from the supply system to take its place. As soon as the proper temperature is - achieved at these extremities, the heating-orifice flow through the return line is shut off to maximize system efficiency. - As a safety to the other devices in the system, a priority valve is integrated into the Parker heater valve. This ensures that even in a cold fluid
