1 Reducing Modular Valve Features RESSURE REUCING MOULAR VALVE to r/min,ma qthis modular valve makes the pressure in part of the circuit lower than that of the main circuit. Specifications Model OG-G-C- OG-G-C-(V)-J OGH-G-- Nominal iameter (Size) / / / weven when pressure changes in the primary main circuit, the reduced secondary pressure is maintained at a constant level.

ISO ISO ISO ---- Handling zwhen using a remote control valve in a vent circuit, certain vent circuit pipe capacities can cause vibration. Because of this, thick steel pipe with an inside diameter of φ mm that is no longer than three meters is recommended. Vent piping cannot be used with the size. If a vent port is required for the size, add the auxiliary code "V". xfor the size, the drainage can be allowed to escape through the T port. In the case of a valve with the auxiliary symbol B, however, run a return pipe from the drain discharge port directly to the tank. cwith the sizes, piping is not required because drainage can be allowed to escape from the gasket side drain port. In the case of a valve with the auxiliary symbol B, however, run a return pipe from the drain discharge port directly to the tank. vnote that a change in drain back pressure causes a change in setting pressure. bwith the, sizes, the flow rate is limited at low pressures. See the - Flow Rate Characteristics on pages - for more information. nnote that a sub plate and installation bolts are not included. See pages - through - if these items are required. m series modular valves do not have an L (R) drain port, so they cannot be used in combination with pressure center type solenoid valves ().,With the, sizes, the control port can be changed by altering the attachment orientation of the back cover. See the installation diagram for more information. After making this change, be sure also to make the other changes in accordance with the model number indicated on the nameplate.
