Check Valves Section Overview This section gives basic specifications for the full line of Eaton screw-in cartridge check valves. Its purpose is to provide a quick, convenient reference tool when choosing Vickers cartridge valves or designing a system using these components. Eaton's Integrated Hydraulics range of direct and pilot operated check valves provides the hydraulic circuit designer with a wide selection of cartridge and in-line products. Two pressure ratings are shown for all products featured in this catalog. The typical application pressure rating is the maximum recommended operating pressure for the valve in a given system. The fatigue pressure rating is the pressure for the valve to be free for infinite life from metal fatigue. All poppet type check valve cartridges have hardened and ground poppets and sharpedged ground steel seats. This provides an excellent product that is dirt-tolerant, has reliable seating, and is suitable for fast cycling with long life. Direct Operated Check Valves Cartridges fit into industry standard cavities and may be supplied for installation in manifolds, or be provided in standard housings having SAE or BSPP ports suitable for in-line mounting. A wide selection of cracking pressures is available from, to,7 bar ( to psi). Thus the opportunity exists to use the valves not only as conventional check but also as low pressure relief valves. Pilot Operated Check Valves These valves are used for: Position load locking As an alternative to counterbalance valves where neither the overrunning loads or release speed are factors in the application. The high pressure 4CK** series pilot-to-open check valves complement the CE series counterbalance cartridges and are physically interchangeable with them. The 4CK**s provide a low cost Alternative to load control when the dynamics of neither overrunning loads nor load release speed are factors to be considered in the design of the hydraulic circuit for the load to be controlled. The pilot-to-open valves positively lock a load from port to port until pilot pressure applied to port is sufficient to unseat the valve. This then permits flow from port to port. The 4CK** covers flow up to L/min (8USgpm). These POC valves are suitable for use in a broad range of load control applications with typical system operating pressures up to 5 bar (5 psi). Features And Benefits Products in this catalog have been fatigue tested for one million cycles at % of rated pressure. Simple load holding device. Low cost alternative to more complex solutions when overrunning loads are not present and / or control of load release speed is not required. Provides high operational efficiency and low spring settings. Valves are offered with a wide variety of standard housings with SAE and BSPP port options in the following configurations: In-line single In-line dual SAE, 4-bolt, code 6 Close coupled, nipple mounted asket mounted single asket mounted dual The Eaton range of direct and pilot operated check valves provides the hydraulic circuit designer with a wide selection of cartridge and in-line products. Unique design provides compact package and low pressure drops that match or exceed current market expectations and provide for excellent repeatability and stability : pilot ratio satisfies simple load holding application requirements, while providing smooth operation and longer operating life. Single Pilot Check Also offered are SPC-8 and SPC- single pilot check valves with pressures to 4 bar (5 psi) and flows to L/min (6 USgpm). These valves operate similar to the 4CK** Series product but offer an opposite flow path which offers the designer a choice of pilot operated check valve when laying out a custom manifold for ease of design and fit the C- cavity Supporting Products Integrated Hydraulics screw in cartridge valves are available in a wide range of mounting configurations and porting options to provide flexibility in developing circuits. Housings are available in either aluminum bar ( psi) or steel 5 bar (5 psi) configurations. All are available with a choice of BSPP (ISO 8/) or SAE style ports. -4.A EATON Screw-In Cartridge Valves E-VLSC-MC-E May 5

SPC-8 - Check Valve Pilot-to-open, poppet type 9 L/min (5 USgpm) 4 bar (5 psi) Sectional View Operation Pressure on the valve port causes the poppet to lift against the spring force, allowing the flow to the cylinder port. Reverse flow is prevented by the poppet reseating. Performance Data Pressure applied to the pilot port will overcome the cylinder port pressure and lift the poppet from its seat, allowing flow from the cylinder to valve port. Features Hardened and ground poppet gives excellent flow capability for valve size, positive sealing and long working life. Cartridge construction allows installation in actuators, manifold blocks and Hydraulic Integrated Circuits. Fits the same cavity as the overcenter valves of a similar size.

Seal kit -76 (Buna-N) -77 (Viton ) Viton is a registered trademark of E.I. DuPont Description Pilot check valves allow flow to pass in one direction, with a low pressure drop, then prevent reverse flow until pilot pressure is applied.

4CKD9 - Check Valve Pilot-to-open, poppet type with decompression stage 9 L/min (4 USgpm) 4 bar (6 psi) Sectional View Operation The ball and poppet are held onto their respective seats by spring force, ensuring positive sealing as long as the pressure on port is equal to or greater than the pressure on port. As soon as the pressure on port exceeds the pressure on port plus the spring force, the valve opens from to. In order to pass flow in the reverse direction, pilot pressure must be applied to port. Once this reaches the required level, the pilot piston acting on the pin in the Center of the poppet lifts the ball off its seat, enabling the fluid to decompress and thus reducing the load pressure acting on port. As the load pressure decreases, the pilot pressure required to open the main stage also decreases and when the correct pilot pressure is reached, the main stage poppet is lifted off its seat by the advancing pilot piston, allowing full flow from to. When calculating the pilot pressure, it must be remembered that any back pressure on port will cause this to increase on a : ratio. Features Decompression stage reduces hydraulic noise on rapid loss of pressure. Precision ground ball and hardened and ground poppet ensure positive sealing and long, trouble-free working life. This valve is directly interchangeable with the 4CK9 check valve and CE*9 series overcenter valve. Performance Data Pilot () Valve () Cyl () Description A decompression pilot check can be used in most applications that use a standard pilot operated check. Free flow in one direction and load holding in the other. The decompression feature allows locked-in pressure to decay in a controlled fashion, reducing hydraulic noise and instability caused by the rapid loss of energy from the actuator. The valve is effective in clamping circuits and when used with intensifiers or when there are high load induced pressures.

4CKKT - Check Valve Dual, pilot-to-open with thermal relief 5 L/min (6.6 USgpm) bar (45 psi) 4 Sectional View Operation Pressure on the valve port causes the poppet to lift against the spring force, allowing the flow to the cylinder port. Reverse flow is prevented by the poppet reseating. Pressure applied to the pilot port will overcome the cylinder port pressure and lift the poppet from its seat, allowing flow from the cylinder to valve port. In dual pilot check valves, each pilot section is cross connected to the opposite line giving automatic pilot operation in both directions. When the pressure in C rises above the setting of the relief valve, the relief valve will open, allowing flow to the V port, relieving pressure on the cylinder. Features Hardened and ground poppet gives excellent flow capability for valve size, positive sealing and long working life.

4KD5 - Check Valve Pilot-to-open with decompression stage 5 L/min (6 USgpm) 7 bar ( psi) Operation In free flow direction, flow through inlet unseats the poppet and flows out of the cylinder port. When the control valve is centered the load is locked. When pilot pressure is applied the piston unseats the small poppet in the center of the main poppet. Flow through this small seat area lowers the load or locked pressure (decompression stage). With load pressure reduced the main poppet is then piloted fully open allowing reverse flow. Features Decompression feature for low pilot pressure requirements and to reduce hydraulic noise on rapid loss of pressure.
