Already well established in many applications, our Hydraulic Cartridge Valves Program is continually supplemented with market-driven solenoid and mechanical valve designs. Hydraulic Cartridge Valves Manufacturers are designed both for the UNF threaded, industry common cavities and particularly for counterbalance valves, in other well known cavity configurations. Exacting performance standards are brought to reality in Bosch Rexroth Compact Hydraulics state-of-the-art production facilities, creating the market’s most cost-effective, highly engineered valves.
The term Hydraulic Cartridge Valves Suppliers commonly refers to pressure, directional, and flow control valves that screw into a threaded cavity. These valves are mostly rated for low flows - 40 gpm or less, although some manufacturers have units that will flow more than 100 gpm. Compact screw-in cartridges help build inexpensive circuits that are reliable and easy to maintain. Screw-in cartridges are most often part of a drilled manifold but can be purchased in individual bodies. The performance and function of screw-in Hydraulic Cartridge Valves is similar to the in-line or sub-plate-mounted valves discussed in Chapter 10.
Slip-in cartridge valves (sometime referred to as logic valves) are different because, except for pressure controls, they are simply 2-way, bi-directional, pilot-to-close check valves. Most circuits using slip-in cartridge valves flow at least 60 gpm and go as high as 3000 gpm. (Several companies make screw-in Hydraulic Cartridge Valves Manufacturers in sizes as small as 15 gpm for use when the special features of logic valves are required at lower flows.) Slip-in cartridges also are compact, have low pressure drop, and operate at pressures up to 5000 psi. Slip-in cartridges can function as pressure, flow, and directional valves.
Another feature is fast response on opening. Because there is no overlap, flow is almost instantaneous after the Hydraulic Cartridge Valves Suppliers receives a start signal. Even when controlling poppet-opening speed, there is no lag in flow response that increases cycle time. Response also is fast on closing because the poppet only opens far enough to pass the flow going through it. This means it does not have to move any extra distance to start to restrict flow and shut it off.
Hydraulic Cartridge Valves Manufacturers are also very versatile when set up with multiple control valves. Many center or crossover conditions can be duplicated by which control valves are open and how they are signaled during a cycle. This means that when designers want to try different valve configurations, they only have to change control valves or control circuitry. This versatility can be applied anytime with the right design parameters up front.
