The Rexroth PPC-R22.1N-T-Q1-P2-NN-FW is a proportional pressure control valve, a product of Bosch Rexroth, commonly used in industrial hydraulic systems to precisely control the pressure of hydraulic fluids. The following are some possible parameters and features of PPC-R22.1N-T-Q1-P2-NN-FW:

Model composition:

PPC: indicates the proportional pressure control valve.
R22.1N: Indicates the size and specification of the valve.
T: Electromagnet type (possibly a custom type specific to the application).
Q1: Electrical interface and plug type.
P2: Connection mode of cartridge valve.
NN: Indicates the control type of the valve, usually electrical proportional control.
FW: indicates a specific function or configuration.
Working pressure range: This proportional pressure control valve is designed to operate within a specific working pressure range, which is usually detailed in the product specification.

Control accuracy: PPC series valves typically have high precision characteristics that allow for precise control of pressure in the hydraulic system.
Dynamic performance: The valve may have a good dynamic response and can be adjusted quickly when the system pressure changes.
Electrical interface: Q1 may indicate specific electrical connection types and specifications, such as plug type, cable length, etc.
Cartridge valve connection: P2 indicates that the valve is connected by a cartridge valve, which is usually easy to install and replace quickly.
Electromagnets: Type T electromagnets may provide specific control characteristics, such as higher response speed or more precise control.
Flow characteristics: The valve has specific flow characteristics, which determine the flow control ability under different pressures.
Environmental adaptability: Rexroth’s PPC series valves are typically designed for use under a variety of environmental conditions, including temperature, humidity and vibration.
Maintenance requirements: The valve may require regular maintenance and inspection to ensure its long-term stable operation.
