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 is a transparent resin plate for placing a label that indicates solenoid valve function, etc. Insert it into the groove on the side of the end plate and bend it as shown in the figure. . When the blanking plate with connector is mounted, it automatically will be “VVQ1000-NC-n” . When ordering this option incorporated with a manifold, suffix “-N” to the end of the manifold part number. It prevents cylinder from malfunctioning by other valve’s 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 it being mounted on all manifold stations, 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 station by means of the manifold specification sheet. . Specify the mounting position by means of the manifold specification sheet. . When ordering this option incorporated with a manifold, specify the EXH block base assembly part number with “.” in front of it beneath the manifold part number. D side U side The manifold block assembly is used between stations for which exhaust is desired to be divided when valve exhaust affects other stations due to the circuit configuration. The EXH passage on the D-side is blocked in the EXH block base assembly. It is also used in combination with an individual EXH spacer for individual exhaust.
