Hydraulic cartridge valves are valves that are threaded to screw into other applications. They can refer to directional, pressure, or flow control valves. Cartridge valves can be referred to as slip-in valves. They are small, affordable, and have quick switching rates. Cartridge valves are ideal if you don’t want to worry about leaks when using high-flow equipment. They are useful in multiple industries. Read More…

How Hydraulic Cartridge Valves Function
Cartridge valves are made of a sleeve, a valve cone, and a closed spring. Pilot-operated check valves with an equal area at both ports are popular because they are easy to install in hydraulic systems. Fluid arriving from either port will push the holding poppet open. These valves are unidirectional and lack communication holes through the poppet to allow fluid to pass behind it. Normally, a thin spring holds the poppet in place during shutdown. It easily succumbs to allow fluid to simply pass through the valve.
Types of Hydraulic Cartridge Valves
Single Pilot Operated Check Valves
Pilot-operated check valves block the flow in one direction until the right pilot pressure is applied. This indicates that the poppet inside the check valve stays sealed in the absence of the required pilot pressure. Once the necessary pressure has been applied, the fluid can freely flow in the opposite direction. This process helps lock the system's dual-acting cylinder. The pilot piston and threaded cartridge valves are the two common hydraulic pilot-operated check valves.
Flow Control and Flow Divider Valves
Hydraulic flow control valves help control the flow rate, which affects pressure; hydraulic flow control valves are crucial. Unregulated speed can harm a hydraulic system’s pumps and actuators or render the entire system ineffective. Flow divider valves divide the flow of the fluid. They can be used in the opposite direction to merge separate hydraulic fluid flows into a single stream. The dividing and combining functions are exact and independent of the flow’s pressure or viscosity.
End Stroke Valves
End stroke valves are mounted on a branch to release pressure. End stroke valves use a pusher to move fluid from one exit to the other. there are open and closed models. Open models are intended to be open and closed by user interaction. These valves can be opened or closed by pushing or pulling on a slider, while some models have fluid levers for simple adjustment. Closed models operate similarly but instead are only opened by user interference. Both versions will immediately and completely stop the flow through the valve when they are closed.
Crossline Relief Valves
Hydraulic crossline relief valves are a popular choice. If your system uses a fixed-volume pump, a relief valve is necessary to safeguard from excessive pressure. There are many kinds of relief valves, including direct-acting and pilot-operated valves.
Hydraulic Diverter and Ball Valves
Hydraulic diverters and ball valves divert flow from a single source to many lines. This is especially helpful in dumping operations. One outlet allows fluid to pass from a shared source to the vital hydraulic component. Simultaneously, the other outlet empties or recycles extra fluid. The second outlet often loops back into the system to minimize waste. Common models include two-way ball valves to 6-way solenoid diverters. Their uses are flexible.
Application of Hydraulic Cartridge Valves
- Deep sea and decompression
- Assemblies for directional controls
- Orifice limiters
- Pressure compensators
- Systems for relieving pressure testing apparatus
