Partial Stainless Steel Type 6380V 1 Paddle Control Water Flow Switch 1.0MPa SPDT Contacts

About this item

• Features: It is used to measure the dynamic state of the liquid flowing through the pipeline, such as: water, ethylene, ethylene glycol and other liquids that have no corrosive effect on copper. When flow rate exceeds set value, fluid drives blade and micro switch, the SPDT contact can connect a circuit and disconnect other circuit. Flow control value is adjustable, repeat action point is stable. Protection grade is IP54, the microswitch contact life is up to 100,000 times Perfect for water treatment system, central air conditioning, water cooling unit. Specification: Model: HFS25 Control mode: Paddle Switch type: SPDT Material: 304 stainless steel body, copper connector, phosphor bronze bellows Connector: 1 25mm Max.working pressure: 1.0MPa Ambient temperature: 0~60 celsius Liquid temperature: 10~100 celsius (Fluid without icing) Contact life: 1000000 times Microswitch Current: 15A Weight: Approx.416g 14.7oz Package List: 1 * Water Flow Switch 5 * Paddle 1 * User manual Installation method: 1. Open the flow switch 2. The switch has been set at minimum flow rate. Turn the adjusting screw counterclockwise to increase the flow setting value. 3. Press the target to check whether the micro switch can work normally. Excessive clockwise rotation of the adjusting screw may to the failure of the flow switch. 4. After the installation, please press the lever of the flow switch several times to check. If there is no click sound, turn the adjusting screw counterclockwise until there is click sound. 5. The adjustment screw of lacquer seal is only used for the first time to adjust the state of flow switch. Please do not change or adjust it. 6. Observe three operating cycles to ensure that the switch and the system to which it is connected are operating properly and cover the switch enclosure promptly. Note: 1. Please check the flow switch carefully before installation. 2. Flow switch can be installed in horizontal pipeline or vertical pipeline with upward liquid flow direction, but not in pipeline with downward liquid flow direction. When installed in the pipeline with upward liquid flow direction, the gravity effect should be considered. 3. HFS flow switch could not be used in the pipe which liquid temperature below freeing point. 4. Arrester must be installed if quickclosing valve fixed downstream. 5. When installing wiring, please pay attention to the following matters: (1). It is absolutely forbidden to impact the wrench on the switch base plate, which will to the deformation and failure of the flow switch. (2). When wiring or debugging, cut off the power supply. (3). When wiring, it is absolutely forbidden to adjust any screws other than micro switch terminals and grounding screws. And connecting the wire carefully, otherwise it is easy to make the micro switch itself position displacement, resulting in the failure of the flow switch; (4). Special grounding screws must be used for wiring, and installation screws cannot be removed. (5). The blade of the flow switch cannot contact with the inner wall of the pipe and other throttles in the pipe, otherwise the switch cannot be reset normally. It is used to measure the dynamic state of the liquid flowing through the pipeline, such as: water, ethylene, ethylene glycol and other liquids that have no corrosive effect on copper. When flow rate exceeds set value, fluid drives blade and micro switch, the SPDT contact can connect a circuit and disconnect other circuit. Flow control value is adjustable, repeat action point is stable. Protection grade is IP54, the microswitch contact life is up to 100,000 times Perfect for water treatment system, central air conditioning, water cooling unit.
