Moog 2-way Slip-in Cartridge Valves - Directional and Pressure Function Product Overview 2-way Slip-in Cartridge Valves are logic elements designed for use in hydraulic manifolds. With a compact design, this product series offers a high power density for high performance hydraulic systems. In addition to the slip-in cartridge valve, a cover and in most cases, a pilot valve are required for the valve to be fully functional. The 2-way Slip-in Cartridge Valves featured in this catalog are designed for 420 bar (6,000 psi) operation and offer the highest nominal flows and lowest pressure drops...

Moog 2-way Slip-in Cartridge Valves - Directional and Pressure Function Description of operation Operating Principle for Directional Function Whether an application requires a simple check (nonreturn) function or something much more complex, it is important to understand the basic operating principles of a directional cartridge valve in order to get the most performance out of the application. Control area ratios A directional control function requires, first of all, a B, C, E or F poppet. These poppets, with a stepped shape, have 3 different control surfaces which is the key to their...

Moog 2-way Slip-in Cartridge Valves - Directional and Pressure Function Description of operation Operating Principle for Pressure Function Pressure relief valves are a vital component of any hydraulic system. These valves are used to limit the maximum permissible hydraulic pressure at the relevant port. Typical applications include limiting pump and cylinder pressures. The limiting of cylinder pressures not only protects the cylinder from damage, but also enables the reliable control of the force applied by the cylinder. Control area ratios Unlike directional valves, the A0 and EX poppets...

Moog 2-way Slip-in Cartridge Valves - Directional and Pressure Function Description of operation Directional Poppet Types - B and C Poppets (Control Area Ratio AA:AX of 1:1.5) BO, BX poppet 4 poppet types (B, C, E and F) are available for directional control functions. This section will focus on 2 of these poppet types: The B and C poppets. BO Poppet The B poppet is the standard stepped poppet for directional control functions. The poppet has a control area ratio AA:AX of 1:1.5 and the flow area is approximately proportional to the poppet stroke. The C poppet is based upon the B poppet and...

Moog 2-way Slip-in Cartridge Valves - Directional and Pressure Function Description of operation Directional Poppet Types - E and F Poppets (Control Area Ratio AA:AX of 1:1.07) EO, EX poppet 4 poppet types (B, C, E and F) are available for directional control functions. This section will focus on 2 of these poppet types: The E and F poppets. EO Poppet The E poppet is available for directional control applications where a smaller control surface in port B and a larger control surface in port A is desired. The poppet has a control area ratio AA:AX of 1:1.07 and the flow area is approximately...

Moog 2-way Slip-in Cartridge Valves - Directional and Pressure Function Description of operation Pressure Poppet Types - AO and EX Poppets AO/KOB and AO/K99 poppet 2 poppets are available for pressure relief function: The AO and EX poppets. AO Poppet (without shaft seal) The AO poppet is designed for conventional pressure relief functions. Due to the fact that the poppet has no control surface in port B, the control area ratio is AA:AX = 1:1. Please note, for a pressure relief function it is important that the pressure in port X not greatly exceeds the pressure in port A, otherwise damage...

Moog 2-way Slip-in Cartridge Valves - Directional and Pressure Function Installation instructions The following instructions will ensure the correct installation and maximum performance of the 2-way Slip-in Cartridge Valve. Ideal cartridge orientation for sleeves with 6 holes Seals Check that all seals and back-up rings are mounted correctly. The back-up rings must not protrude beyond the outer diameter of the o-ring groove. If necessary, remove the back-up ring and ”tighten“ to a smaller diameter, then install the back-up ring again. Grease all outer seals slightly prior to installing the...
