(6 mm) Blow-Out Hole Lincoln St. Louis Fitting RATING psig (bar g ) A. Be sure to apply the proper rupture disk to match your blow-out fitting type, see Figure 4-1:, and application pressure. Generally the rupture disk should be rated about 1000 psig (70 bar g ) greater than the highest MAWP cylinder. B. See Technical Manual Section 1, Fastener Tightening Values Table or the toolbox torque tables (ER-63) for blow-out fitting cap tightening torque. Do not over tighten cap or rupture pressure can be reduced. ARIEL P/N 5100 (352) PT0200CB 10,200 (703) PT0201CD C. All tubing down stream from a force feed pump for a pump circuit rated 5500 psig (380 bar g) or greater (orange, pink and blue disks), that is circuits with any cylinders greater than 3600 psig MAWP (248 bar g ), should be 1/4 inch x 0.065 (6.4 x1.7 mm) heavy wall stainless steel high pressure tubing. Rated tubing pressures are calculated from equations in ASME/ANSI B31.3 code for pressure piping, based on maximum outside diameter and minimum wall thickness. When grade 316 stainless steel tubing is specified on new compressor sales orders, 1/4 inch x 0.065 (6.4 x 1.7 mm) tubing is provided, regardless of rupture disk or cylinder ratings. D.

FOR MODELS: JGZ AND JGU SECTION 4 LUBRICATION Divider Valves NOTE: REFER TO PARTS BOOK FOR THE FRAME BEING SER- VICED FOR ASSEM- BLY DRAWINGS, PARTS LIST AND REPAIR KITS THAT ARE AVAILABLE FOR DIVIDER VALVES. Description Divider valves are comprised of three to eight valve blocks fastened to a segmented baseplate. O-rings are used to seal between the valve blocks and the base plate and between the base plate segments. These divider valves are used in a single line, progressive lubrication system and can be used for dispensing oil or grease. Valves and base plate segments are supplied with Viton O-rings (90 Durometer). Piston Cross Port Plate Divider Valve Block Distribution Block Divider Valve - Cap Screw Check valves are installed at the outlets of all lube ports. Inlet Block Intermediate Blocks Discharge Port (Outlet) Correct Port Position is Off-Center Toward Inlet Block End Block Valve blocks containing metering pistons discharge a predetermined amount of lubricant with each cycle. Valve blocks can be single or twin and can be externally singled or cross-ported. Outlets not to be used when singling or cross-porting must be plugged. A by-pass block can be used in any position on the base plate. The use of a by-pass block allows the addition or deletion of lubrication points without disturbing existing tubing. Both outlets under a by-pass block must be plugged. The valve blocks and by-pass blocks are fastened to a base plate mounted on the machine to be lubricated. The base plate contains the divider valve's inlet and outlet connections, interrelated passageways and built-in check valves. All piping of lubricant to and from the divider valve is connected to the base plate. The base plate consists of one inlet block, three to eight intermediate blocks, one end block and three tie rods. O-ring seals are included with the base plate segments. The valve block capacity of each base plate is dependent upon the number of intermediate blocks in the baseplate. There must be a minimum of three working valves on each valve and base plate assembly. PAGE 4 - 32 7/09 Inlet Tie Rod O-Rings Check Valve FIGURE 4-2: DIVIDER VALVES DISTRIBUTION BLOCK - TYP- ICAL
