E-P HYREG R VY Series Construction/Component Parts/Working Principle VYD Cover Body Pressure sensor Feedback passage Control circuit VYA, VYB (Pilot valve: VYD- ) (R) Solenoid valve (P) (A) Sub-plate Port P Power supply Command signal The VYD, which is the smallest direct drive, consists of a solenoid, pressure sensor, control circuit, body cover, and a sub-plate. The type with sub-plate can be used alone, and the type without sub-plate can also be used as a pilot valve. All types are the same in terms of connection. Working principle When the command signal is below VDC, (refer to page 99) the solenoid valve is inactive, and the port (A) pressure is zero. When a command signal between and 5 VDC is provided, the solenoid is activated. The port (A) pressure is fed back to the control circuit by the pressure sensor. The control circuit compares the feedback signal with the size of the command signal that was provided, and: ) If the feedback signal is smaller, current is supplied to the solenoid valve to raise the port (A) pressure [from (P) to (A)]. ) If the feedback signal is greater, current is not supplied to valve to reduce the port (A) pressure [from (A) to (R)]. The above processes ) and ) are repeated at high speeds to set the port (A) pressure. Circuit Power supply Input signal Solenoid valve (P) (R) Control circuit Working principle The supply [(P) to (A)] valve of valve y and the exhaust [(A) to (R)] valve close due to the balance between actuating forces F and F. Actuating force F is applied to the right surface of pressure regulation piston e by the pilot pressure (pilot valve assembly w: VYD- ), and actuating force F is applied to the left surface of the pressure regulation piston by the port and pressure that passes through the feedback passage. Thus, the port (A) pressure that coprresponds to the pilot pressure is established. When the port (A) pressure becomes higher than the pilot pressure, F becomes greater than F. This causes only the pressure regulation piston to move to the right, and the exhaust valve seat to open, allowing the air to be discharged from port (A) to port (R). When the port (A) pressure drops to reach a balance, the regulator returns to the set state. Conversely, if the port (A) pressure is lower than the pilot pressure, F becomes lower than F. This causes the pressure regulating piston to move the valve to the left, and the supply valve seat to open, allowing the air to be supplied from port (P) to port (A). When the port (A) pressure balances, the regulator reuturns to the set state.

A c t u a t i n g f o r c e F i s a p p l i e d t o t h e t o p surface of pressure regulation piston r by the pilot pressure (pilot valve assembly q: VY D B - ), and actuating force F is applied to the bottom surface of the piston by the port (A) pressure that pases through the feedback passage. Thus, the port (A) pressure that corresponds to the pilot pressure is established. The poppet valve, which maintains a pressure balance with the port (A) pressure, is backed up by spring t (refer to the diagram on the left). When the port (A) pressure becomes higher than the pilot pressure, F becomes higher than F. This causes the pressure regulation piston to move upward, and the top poppet valve to open, allowing the air to be discharged from port (A) to port (R). When the port (A) pressure drops to reach a balance, the regulator returns to the state shown in the diagram to the left. Conversely, if the port (A) pressure is lower than the pilot pressure, F becomes less than F. This causes the pressure regulation piston to move downward, and the lower poppet valve to open, allowing the air to be supplied from port (P) to port (A). When the port (A) pressure rises to reach a balance, the regulator returns to the state shown in the diagram to the left.

VY Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 5 for Safety Instructions and each Best Pneumatics for Precautions on every series. Piping Caution Tightening the fittings and their torque When screwing fittings into the valves, make sure to tighten them to the proper torque values given below. Connection thread: M5 First, tighten by hand, then use a wrench appropriate for the hexagon flats of the body to tighten an additional /6 to / turn. A reference value for the tightening torque is to.5 N m. For the fitting with sealant R or NPT, first, tighten it by hand, then use a wrench appropriate for the hexagon flats of the body to tighten it a further two or three turns. For a tightening torque guide, refer to the table below. Connection thread size (R, NPT) Operating Fluid Caution Caution Wires to be Used Caution Proper tightening torque (N m) to 5 to 5 to to 5 to 6 to to to 5 to 5. If drainage or debris is present in the supply pressure line, the sliding resistance of the main valve or piston, etc. increases, resulting in a malfunction. Therefore, in addition to the air filter (SMC s AF series), make sure to use a mist separator (SMC s AM, AFM series). Concerning the quality of the operating air, refer to SMC s air preparation equipment selection guide (pages and ).. Make sure to perform a maintenance periodically on air filter and mist separator (by discharging the drain and cleaning a filter element or replacing with new one). Pressure Gauge For products with pressure gauge, use caution about the durability of a pressure gauge, since it may be affected by the sudden pressure changes during operation. Use core shielded wires measuring.5 (mm ) for the power supply and signal lines according to the respective number of conductors. When connecting the shielded braided wire, connect it to the ground of the signal generator. As a rule, the electro-pneumatic hybrid regulator should be installed in a location that is free of noise or is shielded. If it must be installed in an environment with poor noise conditions, eliminate the power supply noise by using a line filter, Z-wrap, or a spark killler on the V power supply or signal source line. The length of the power suply and signal lines must be kept as short as possible. Power supply Signal generator (Input signal) To field ground (F. G.) Shielded wire To ground (GND) Terminal no. Details of wire connection Power supply Command signal GND (COMMON) How to Use DIN Terminal Caution Wiring procedures. Loosen the retaining screw and pull the connector from the solenoid valve terminal block.. Remove the retaining screw, insert a flat head screwdriver into the groove below the terminal block and pry it up to separate the terminal block from the housing.. Loosen the terminal screws (slot head screws) on the terminal block. Then, in accordance with the wiring procedure, insert the cord of the lead wires into the terminals and tighten the terminal screws to secure in place.. Tighten the ground nut to secure the cord. Outlet changing procedure After the terminal block has been separated from its housing, reassemble the housing in the desired direction (in four 9 increments) to change the direction of the cord outlet. Precautions Kindly insert the connector straight in without tilting it, and pull it out straight. Applicable wire Ground nut Cord external diameter: ø to ø6.5 c.f..5 mm core wire (JIS C 6 equivalent) Connector part no.: VK-- Input Signal Caution Retaining screw Housing (Rated symbol) Terminal screw ( locations) Washer Grommet (Rubber) (Light mounting position) Terminal block Slit area Input signal when out of operation There is dispersion in operation start voltage (current) for the input signal. (Refer to page 99.) If the command signal when out of operation exceeds the lower limit of the operation start voltage (current), the solenoid valve inside the pilot valve starts to activate and may be in the operation state. The service life of this product varies depending on the operating time of the solenoid valve inside the pilot valve. Be sure to cut off the command signal when the pressure control on the outlet side is not required, such as when the line is temporarily halted, etc. (Refer to Service Life below.) Service Life Caution The pilot valve service life is approximately to 5 operating hours. (When using AF + AFM) This may be approximately hours with ultra-dry air (dew point C or equivalent). For the low wattage specification (X9), the service life is approximately 7 operating hours. (When using AF and AFM) Bleed Caution Since the pilot solenoid valve enters the normally operating status and the air is discharged continuously from the pilot EXH port (port (R) for VYD, VYA and VYB ) in the pressure setting status, the bleed sound is produced. However, this is not an abnormal phenomenon. Related Products: Silencer (AN series) Noise reducing effect: db or more. Large effective area Refer to Best Pneumatics No. 7 for details.
