Introduction to Pilot-Operated Check Valves (Lock Valves)

Application: Pilot Operated Check Valves (Lock Valves) are designed to lock a cylinder, without leakage, while a control valve is in a neutral position. Lock Valves function as Check Valves, allowing flow to a cylinder and blocking reverse flow until pilot pressure is applied to unlock the circuit. These valves may be used to prevent movement of a load while the pressure source is inactive. A 4-way control valve is required for all lock valve circuits, including single acting cylinders, in order to apply unlocking pressure to the pilot circuit. A control valve with a free-flow (motor) spool should be used on any circuit which includes a lock valve to prevent pressure build-up between the lock valve and the control valve.

Unlocking Pressure (Single Acting Cylinders): Pressure required in the pilot circuit = 25% of the locked pressure.

Unlocking Pressure (Double Acting Cylinders): To unlock Blind End of cylinder, pressure required in the pilot circuit = Blind End Locked Pressure/[4.0 - (Rod End Locked Pressure/((Cyl Area - Rod Area)/Cyl Area)]. To unlock Rod End of cylinder, pressure required in the pilot circuit = Rod End Locked Pressure/[4.0 - (Head End Locked Pressure/((Cyl Area - Rod Area)/Cyl Area)].

Caution: When the rod end of a double acting cylinder is locked, if the rod diameter exceeds approximately 75% of the cylinder diameter, unlocking pressure becomes excessive and a lock valve should not be used.

Important Lock Valve Basics: Always follow catalog recommendations and application directions • Consult with our representative or the factory when in doubt • When applying lock valves to life carrying machines such as boom/utility type equipment, do not separate the valve from the actuator... close-couple the valve to the actuator • Do not use pilot operated check valves in load holding applications where either overrunning loads are possible, or load release speed is critical • Care should be taken to ensure the load is supported by mechanical means when servicing or removing the valve (CAUTION: When servicing the equipment, trapped pressure may be present in the holding valve circuit. Carefully bleed down the trapped pressure before disassembly) • The cylinder and it's seals must be in good condition.

Introduction to Counterbalance Valves (Overcenter Valves)

Overview: There are now many types of overcenter or counterbalance valves available to the designer of hydraulically operated machines, each one has its own place and specific benefits to the user. The function of these valves can be divided into three basic groups. 1. Load Holding; where the overcenter valve prevents the movement of a load when the directional valve is in the neutral position. Permitting the use of open center directional valves and negating leakage past the spool of closed centre directional valves. 2. Load Control; where the overcenter valve prevents the actuator running ahead of the pump due to the load induced energy thereby eliminating cavitation in the actuator and loss of control. 3. Load Safety. In the case of hose failure an overcenter valve mounted onto or into an actuator will prevent uncontrolled movement of the load. When a boom is used as a crane then hose failure protection is vital as the loss of load control could cause damage to people or property. Each of these functions is applicable to linear or rotary motion.

Application: Overcenter valves give static and dynamic control of loads by regulating the flow into and out of hydraulic actuators. When installed close to or within an actuator, the overcenter valve will stop runaway in the event of hose burst and if open center directional control valves are used, will allow thermal expansion relief of the hydraulic fluid. The overcenter cartridge is ideal for mounting directly into a cavity machined in the body of the cylinder, motor or rotary actuator. The cartridge can also be mounted directly to the ports via a specifically machined body as part of an integrated circuit or single unit, or contained within one of the standard line bodies. Single overcenter valves are normally used when the load is unidirectional, for example an aerial platform or crane and dual overcenter valves are used for controlling loads in both directions for motor applications or for cylinders going over center.

Back Pressure: Overcenter valves should not be subjected to back pressure, as this will affect performance and can cause unstable operation. If back pressure cannot be avoided, as an option, a vented spring cavity design should be selected.

Operation: The standard overcenter valve can be described as a pilot assisted relief valve with an integral free flow check. The difference between this design of valve and a pilot check is that the check valve will open fully as soon as the pilot pressure is sufficient to open the valve because the only resistance to opening is the pressure locked in to the cylinder port. With an overcenter valve the pilot pressure has to overcome the force of the spring which is reduced by load pressure. This ensures a gradual opening and a metering of the flow as it passes the poppet. Overcenter valves consist of a poppet that seals flow from an actuator, a check element, which permits free flow to the actuator and a pilot section that opens the poppet allowing flow from the actuator at a controlled rate.

Pilot Ratios: Generally, lower pilot ratios consume more energy for load control but provide more stability. Pilot ratios should then be selected to give good controlability with a minimum of energy loss. Overcenter valves are available with various pilot ratios.

Equal Area Valves: The equal area valve is used when pilot pressure must be set independent of any load-induced pressure, such as on a winch with a brake, where brake release pressure must be obtained before motion is allowed.

Pilot Pressure Formula: The check section allows free flow into the actuator then holds and locks the load against movement. The pilot assisted relief valve section will give controlled movement when pilot pressure is applied. For most applications the relief setting should be approximately 1.3 times higher than the maximum load induced pressure. This ensures that with the maximum load on the actuator the valve will remain closed until pilot pressure is applied. The pilot pressure required to open the valve will depend on the pilot ratio that is the ratio between the relief area and the pilot area. The pilot pressure can be calculated: Pilot pressure = (Valve Setting - Load Pressure)/Pilot Ratio. Example: Valve Setting is 4000 PSI. Load Pressure is 1000 PSI. Valve Ratio is 3:1. Pilot Pressure = (4000-1000)/3, resulting in 1000 PSI required to start to move the load.

Important Holding Valve Basics: Apply in circuits to prevent loads from dropping faster than input flow would allow • Use on the outlet of the controlled device (meter out) • Always follow catalog recommendations and application directions • Consult with our representative or the factory when in doubt • NEVER apply a holding valve with a an unequal area to outriggers or stabilizers • Do not expect motors to hold without mechanical gearing or brakes. Motors have internal clearances which will allow rotation to occur even when the overcenter valve does not leak • When applying overcenter valves to life carrying machines such as boom/utility type equipment, do not separate the valve from the actuator... close-couple the valve to the actuator • Care should be taken to ensure the load is supported by mechanical means when servicing or removing the valve (CAUTION: When servicing the equipment, trapped pressure may be present in the overcenter valve circuit. Carefully bleed down the trapped pressure before disassembly) • When rebuilding machinery, you should replace rather than repair the overcenter valve • The cylinder and it's seals must be in good condition.

Features: Overcenter valves give static and dynamic control of loads by regulating the flow into and out of hydraulic actuators. The check section allows free flow into the actuator then holds and locks the load against movement. The pilot assisted relief valve section will give controlled movement when pilot pressure is applied.

Application: Single overcenter valves are normally used when the load is unidirectional, for example an aerial platform or crane and dual overcenter valves are used for controlling loads in both directional for motor applications or for cylinders going over center.

Pilot Ratios: 4:1 Best suited for applications where load varies and machine structure can induce instability. 8:1 Best suited for applications where the load remains relatively constant.

Pressure Rating: 5000 PSI (CAUTION: Pressures over 3000 PSI require steel housing) Rated Flow: 23 GPM Temperature Range: -22° to +194°F Recommended Filtration Level: 18/13 Cartridge: Model 1CE90, sold separately. Housing: Cavity size A12336, sold separately. page 442
