INTRODUCTION & FEATURES IN BRIEF OPERATOR HEAD 350 bar service. Sizes from DIN 016 to DIN 100. Slip-in cartridge insert valves can provide the following functions: a) Check valve. b) Flow control. c) Pressure regulating. d) Directional control. e) Decompression control. f) Special combinations. A single cartridge can provide more than one function with proper operator circuiting. Cartridges of the same size but different ratios are interchangeable. Cartridges are small, compact and handle high flow rates. Individual cartridges can be sized to satisfy circuit flow rates. Different size...

OPERATION OF SLIP-IN CARTRIDGE INSERT VALVES Figure 4. port A area(A A) is unity (1.0), effective Pot B area (AB) is zero. Therefore, top plunger area AW is 1 + 0 = 1. Ratio of this valve plunger is expressed as 1:1. Figure 5. port A area(A A) is unity (1.0), effective Pot B area (AB) is half of port A area (0.5). Therefore, top plunger area A W is 1.0 + 0.5 = 1.5. Ratio of this valve plunger is expressed as 1:1.5. PILOT CONTROL PRESSURE PLUS SPRING FORCE ACTS ON FULL AREA AW. Figure 6. port A area(A A) is unity (1.0), effective Pot B area (AB) is same as port A area (1.0). Therefore, top...

DIMENSION FOR INSERTING CARTRIDGE VALVE A NOTES: -Pilot valve may exceed B1 & B2 dimensions. -The location of working port B (D4) may be anywhere within the location of T1T5 as long as the minimum shoulder length T9 is maintained. The center line of working port B may be arranged at other angles than 90º with respect to D1 -The depth and angles of the pilot connections are arranged by the function and location of the valves in the manifold. (D7) T3 -Recommended thread engagement for ferrous materials (T6 y T11). INSTALLATION DIMENSIONS PER DIN 24 342-C & N.F.P.A. M/2 PORT A: WORKING PORT...

OPERATOR W/STROKE LIMITER-TYPE “B” And adjustment screw limits the travel of a floating pin which in turn limits the amount the plunger can open. Thus, it results in (adjustable) throttling of flow through the insert valve. For fine adjustment, it is suggested a cartridge plunger with a cushion nose be used. It is suggested the adjustment screw be cut off at a length corresponding to minimum derived flow to prevent accidentally locking the valve in the closed position.
