Also, it is used with an individual SUP spacer to shut off the air supply. . Specify the station position on the manifold specification sheet. When using block plates for SUP passage, indication label for confirmation of the blocking position from outside is attached. (One label of each) . When ordering a block plate for SUP incorporated with the manifold, a block indication label is attached to the manifold. When the exhaust from a valve interferes with other stations in the circuit, this is used between stations to separate exhausts. Also, it is used with an individual EXH spacer to shut off the exhaust of individual valves. . Specify the station position on the manifold specification sheet. . Be sure to discharge the exhaust inside the EXH passage from the R port of the SUP/EXH block, etc. so that the exhaust pressure is not sealed. When using block plates for EXH passage, indication label for confirmation of the blocking position from outside is attached. (One label of each) . When ordering a block plate for EXH incorporated with the manifold, a block indication label is attached to the manifold. It prevents cylinder malfunction caused by other valve exhaust. Insert it into R (EXH) port on the manifold side of a valve which is affected. It is effective when a single action cylinder is used or an exhaust center type solenoid valve is used. . When a check valve for back pressure prevention is desired, and is to be installed only in certain manifold stations, clearly write the part number and specify the number of stations on the manifold specification sheet. . When ordering this option incorporated with a manifold, suffix “-B” to the end of the manifold part number. P R P R D side U side D side U side Caution Plug-in Unit Series SQ1000 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. If the exhaust resistance becomes large, select a built-in valve type with rubber seal. 2. When a back pressure check valve is mounted, the effective area of the valve will decrease by about 20%. 3. Since 4 port specification valves (5 (R1) and 3 (R2) are common) are used, back pressure cannot be prevented with dual 3 port valves. 1375 SY SJ SY SV SYJ SZ VF VP4 S0700 VQ VQ4 VQ5 VQC VQC4 VQZ VFS VFR VQ7 SQ B
