It is also used in combination with an individual EXH spacer for individual exhaust. . Specify the mounting position by means of the manifold specification sheet. Back pressure check valve assembly [-B] VVQ2000-18A 1. The manifold installed type back pressure check valve assembly is assembly parts with a check valve structure. However, since slight air leakage against the back pressure is allowed due to its structure, adverse effects of the back pressure due to increase in exhaust resistance cannot be prevented if the manifold exhaust port and other exhaust ports are put together for piping or if the piping diameter is narrowed. As a result, this may cause the actuator and air operated equipment to malfunction. So, be careful not to restrict the exhaust air. 2. When a back pressure check valve is mounted, the effective area of the valve will decrease by about 20%. It prevents cylinder malfunction caused by other valve exhaust entry. Insert it into R (EXH) port on the manifold side of a valve which is affected. It is effective when a single-acting cylinder is used or an exhaust center type solenoid valve is used. . When ordering this option incorporated with a manifold, suffix “-B” to the end of the manifold part number. Note) When a back pressure check valve is desired, and is to be installed only in certain manifold stations, clearly indicate the part number and specify the mounting position by means of the manifold specification sheet. Indication labels to confirm the blocking position are attached. (Each for EXH passage and SUP/EXH passage blocking positions) . When ordering a block plate incorporated with a manifold, a block indication label is attached to the manifold. . When ordering a block plate incorporated with a manifold, a block indication label is attached to the manifold. When different pressures are supplied to a manifold, a SUP block plate is used to block the stations under different pressures. . Specify the mounting position by means of the manifold specification sheet. Indication labels to confirm the blocking position are attached. (Each for SUP passage and SUP/EXH passage blocking positions) When valve exhaust affects other stations due to the circuit configuration, this spacer is used for individual valve exhaust. (One station space is occupied.) Block both sides of the individual valve EXH station. (Refer to the application example.) . Specify the spacer mounting position, as well as the EXH passage blocking position by means of the manifold specification sheet. The block plate is used in one or two places for one set. (Four EXH block plates (2 sets) for blocking EXH passage are attached to the individual EXH spacer.) . As a standard, electric wiring is connected to the position of When the same manifold is to be used for different pressures, individual SUP spacers are used as SUP ports for different pressures. (One station space is occupied.) Block both sides of the station, for which the supply pressure from the individual SUP spacer is used, with SUP block plates. (Refer to the application example.) . Specify the spacer mounting position and SUP passage blocking position by means of the manifold specification sheet. The block plate is used in one or two places for one set. (Two SUP block plates for blocking SUP passage are attached to the individual SUP spacer.) . As a standard, electric wiring is connected to the position of the manifold station where the individual SUP spacer is mounted. . If wiring is not required for stations equipped with spacers, enter “X” in the special wiring specifications column in the manifold specification sheet. It is used by attaching on the manifold block for being prepared for removing a valve for maintenance reasons or planning to mount a spare valve, etc. C8 N9 C8 N9 SUP passage blocked SUP/EXH passage blocked EXH passage blocked SUP/EXH passage blocked D side U side D side U side Series VQC2000 the manifold station where the individual EXH spacer is mounted. . If wiring is not required for stations equipped with spacers, enter “X” in the special wiring specifications column in the manifold specification sheet. . Do not install any back pressure check valve on the manifold station, on which the spacer is to be mounted. When installing the back pressure check valve on other manifold station, be sure to specify the manifold station position on the manifold specification sheet instead of ordering by specifying the manifold option symbol “B”.
