CLSSIC ilot valve CD4-RV D SHEE 294 297 Description SVB pilot valve is a small smooth valve, based on homas Magnetes propotional pressure reducing valve, that controls a limited-flow control feed to a separate piloted main valve on a machine. ypically, this valve controls a high pressure or high flow feed. SVB pilot valves are useful because they allow a small and easily operated feed to control a much higher pressure or higher flow feed, which would otherwise require a much larger force to operate. Features Stackable housing with measuring point. Valve. Integrated relief function. Compact dimensions. Low leakage. recise current vs pressure control. eflon coated bronze bearings. Excellent Repeatability. Highest quality standard. Small valve to valve variance. Flexibility. echnical data Benefits Easy to expand the valve to add functions and socket for a pressure sensor. Easy to install on existing installation. rotection against pressure spikes. Easy to fit in small spaces. Lower energy losses. Excellent controllability. ort size housing R 1/4 Material housing EN W-82 otal weight singel ppr valve 71,g otal weight singel ppr valve 7,g otal weight dubble ppr valves 113,g otal weight dubble ppr valves 114,g Small hysteresis, improved resolution.
