PRESSURE REDUCING MODULAR VALVE. 40 to 300l/min 25,35MPa

1 RSSUR RU UR VV Reducing to l/min,a eatures qhis modular valve makes the pressure in part of the circuit lower than the main circuit. wven when pressure changes in the primary main circuit, the reduced secondary pressure is maintained at a constant level. eaximum perating :, a {, kgf/cm } Specifications odel o ominal iameter (Size) aximum Working a{kgf/cm } aximum low Rate l/min / {} / {} andling zwhen using a remote control valve in a vent circuit, certain vent circuit pipe capacities can cause vibration. ecause of this, thick steel pipe with an inside diameter of φmm that is no longer than three meters is recommended. Vent piping cannot be used with the, sizes. xwith the, sizes, the flow rate is limited at low pressures.

See pages - through - if these items are required. m series modular valves do not have an (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. fter making this change, be sure also to make the other changes as in accordance with the model number indicated on the nameplate..use the port control valve concurrently with the size central all-portblock () solenoid valve if when the valve is in the central position and external pressure may cause the pressure at the control port to exceed the set pressure. ontrol port : port : port ominal diameter (size), ounting method : asket type reducing (and check) modular valve -
