5 Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 5 for Safety Instructions and pages 543 to 54 for Flow Control Equipment Precautions. Design/Selection 1. This product cannot be used for accurate and precise intermediate stops of the actuator. Due to the compressibility of air as a fluid, the actuator will continue to move until it reaches a position of pressure balance, even though the pilot check valve closes with an intermediate stop signal. 2. This product cannot be used to hold a stop position for an extended period of time. Pilot check valves and actuators are not guaranteed for zero air leakage. Therefore, it is sometimes not possible to hold a stop position for an extended period of time. In the event that holding for an extended time is necessary, a mechanical means for holding should be devised. 3. Consider the release of residual pressure. Actuators may move suddenly due to residual pressure, which can be dangerous during maintenance procedures. 4. When used in a balance control circuit, there are instances in which the check valve cannot release, even though the pilot pressure is 5% of the operating pressure. In these cases, the pilot pressure should be the same as the operating pressure. 5. For reference, SC has conducted endurance tests in which ON, OFF operation of the check valve was performed at the maximum operating pressure, with a confirmed endurance of 1 million operations. Since the tests were performed under limited conditions, use caution in evaluating the results.. The check valve has a construction, in which it is closed by the differential pressure generated when the inlet pressure (IN side) or outlet pressure (OUT side) solenoid valve is switched. Be aware that the check valve does not close completely and the outlet pressure (OUT side) may drop when the inlet pressure (IN side) drops gently and the differential pressure becomes smaller than the minimum operating pressure or cracking pressure. -F TH D -FE -FG -FP -F -D -T V R Q Installation 1. When mounting, please firmly align the tool with the hexagon width across flats of the pilot body. If the hexagon width across flats is damaged as a result of failure to properly align the tool, the pilot body will be deformed, and poor pilot operation may result. Air source 1. If moisture enters the inside of the connecting piping, the cover may corrode, and it may lead to a pilot operation malfunction. 773
