BUCHER HYDRAULICS

Bucher Hydraulics cartridge valves are offered in several industry-standard cavity sizes. From the product range, C10-25 and C12-30 are common. The C10-25 cavity is used for counterbalance valves such as the CBPA series, while C12-30 is used for pressure control valves like the PRRS series. These cavities correspond to nominal flow capacities and are compatible with many manifold designs. When selecting a valve, confirm the cavity size matches the manifold port. Bucher provides detailed cavity dimensions in its technical literature. 3G Electric stocks valves in these sizes and can assist with cross-referencing part numbers.

The QXM series hydraulic motors have maximum pressure ratings of 3045 psi or 4641 psi, depending on the model. For example, the QXM52-050N is rated to 3045 psi with a maximum speed of 4500 RPM, while the QXM83-160N330-03 is rated to 4641 psi with a maximum speed of 3500 RPM. Displacements range from 0.2 to 9.9 cu in/rev. Lower displacement motors generally achieve higher speeds, up to 6000 RPM. These ratings apply under continuous operating conditions; intermittent limits may be higher. Always verify the specific model's data sheet for exact performance curves.

Bucher Hydraulics QXM motors are available with SAE A, SAE B, and SAE C two-bolt mounting flanges, as well as a 2-hole flange conforming to ISO 3019/1 (SAE). The mounting flange determines the pilot diameter and bolt circle, which must match the machine interface. For instance, the QXM22-008N350-V uses an SAE A 2-bolt flange, while the QXM52-050N uses SAE B. Shaft sizes and port connections also vary by model. When replacing a motor, confirm the mounting flange, shaft diameter, and port type to ensure compatibility. 3G Electric lists these specifications for each SKU.

Bucher Hydraulics counterbalance cartridge valves, such as the CBPA series, are screw-in valves designed to control overrunning loads. They prevent uncontrolled load descent by maintaining a set pressure in the return line until sufficient pilot pressure opens the valve. The CBPA-10-N-C-0-50 features a screwdriver adjustment and a C10-25 cavity. These valves are commonly used in hydraulic circuits for holding loads, such as in winches or boom cylinders. The adjustment allows setting the opening pressure to match the load. Proper sizing requires considering load pressure, pilot ratio, and flow rate. Consult the product data sheet for specific performance characteristics.

Bucher Hydraulics cartridge valves typically have steel bodies and nitrile (NBR) seals. The steel construction provides durability and resistance to high pressures. Nitrile seals are compatible with mineral-based hydraulic fluids and operate across a temperature range suitable for most industrial applications. For specialized fluids or extreme temperatures, alternative seal materials may be available. The valve adjustment mechanisms, such as screwdriver or hex, are also steel. These material choices are standard for the PRRS and CBPA series. When ordering, verify the seal material matches the system fluid to avoid premature failure.
