Speed Reducers: They can be used in conjunction with motors to reduce the output speed of the motors and increase the output torque to meet the requirements of different equipment for speed and torque. Parker's speed reducers have the characteristics of high efficiency, reliability, and durability, and are widely used in various automated production lines and mechanical equipment.
Encoders: They are used to measure information such as the speed and position of the motor and feed it back to the control system to achieve precise control of the motor. Parker's encoders have the advantages of high precision, high resolution, and strong anti-interference ability, and can provide accurate position and speed feedback signals for the automation system.
Fluid Control Products:
Proportional Valves: Such as proportional directional control valves, proportional pressure valves, etc., they can continuously adjust parameters such as the flow rate and pressure of the fluid according to the input electrical signals to achieve precise control of the fluid. For example, the D41FCE01FC1NB70 proportional directional control valve adopts a spool/sleeve design, has high-precision pilot control and sensitive flow adjustment capabilities, and is suitable for various mechanical equipment and automatic control systems.
Directional Control Valves: Including electromagnetic directional control valves, manual directional control valves, etc., they are used to control the flow direction of the fluid to achieve the switching and control of the fluid in the automation system.
Hydraulic Pumps: They are the power source of the hydraulic system. Parker's hydraulic pumps have the characteristics of high efficiency, reliability, and durability, and can provide stable hydraulic power for automated equipment. For example, different types of hydraulic pumps such as piston pumps and gear pumps can meet different flow rate and pressure requirements.

Parker's pipe fittings and connectors have a variety of types and characteristics. The following are some common ones:
Compression Tube Fittings:
EO Fittings: Pioneered by Parker Hannifin engineers in the 1930s, they are famous for their small size and high-pressure capabilities. For example, the EO-Plus fittings have better corrosion resistance and higher pressure-bearing capacity. The EO-LUB lubrication process reduces the assembly torque by 25%. They have reliable assembly operation, over-tightening protection function, excellent spring effect, galvanized surface treatment without hexavalent chromium, and high versatility. The EO2 fittings adopt an elastic seal design and can be used in high-temperature environments. For corrosive media, FKM fluororubber can be selected to achieve a leak-free connection. The EO2-Form is a new generation of high-pressure formed pipe fittings products. Based on the EO2 elastic seal technology and using a cold forming process, it has higher connection stiffness and reduced pre-installation torque. Compared with traditional welded joints, it is faster and more convenient to process and has excellent seismic performance.
Ordinary Compression Tube Fittings: These fittings are easy to assemble, can provide good connection strength and sealing performance, are suitable for a variety of fluid transmission systems, and can be disassembled and installed multiple times. The ferrule has a spring effect and can absorb vibrations and pressure pulses in the system, performing well in some vibrating working conditions.
Flared Fittings:
By flaring the end of the tube and then matching it with the conical surface of the fitting, a sealed connection is formed. This type of fitting is suitable for the connection of thin-walled pipes, is simple to install, and does not require special tools. Flared fittings have good sealing and pressure resistance performance and are often used in hydraulic systems, pneumatic systems, etc.
Welded Fittings:
The fitting and the tube need to be welded to achieve the connection. Welded fittings have high connection strength and good sealing performance and are suitable for harsh working conditions such as high temperature, high pressure, and high corrosion. However, the welding process requires professional equipment and technology, and the installation and maintenance are relatively complex.
Quick Connectors:
They are an automatic connector device. Using Parker's unique quick connector technology, they can achieve quick disassembly and installation. During the disassembly and installation process, the connector can be effectively controlled and protected, thus achieving quick, reliable, and safe connection operations. They have the characteristics of improving work efficiency, protecting the circuit from interference, being waterproof, dustproof, resistant to high temperature, anti-aging, etc., can effectively resist harsh environments, and extend the service life. They are widely used in industries such as electronics, electricity, machinery, and automobiles, and can be used for the connection of circuits such as communication, power supply, and signals, as well as for the connection of various pipelines and lubricating oil pipelines of mechanical equipment.
Pipe Thread Fittings:
They provide a variety of thread types, including NPT, NPTF, NPSM, BSPT, BSPP, SAE O-ring boss (ORB), ISO 6149, and metric, etc. These fittings are compact in size, efficient, resistant to high temperature. The straight thread fittings have unlimited reusability, elastic sealing, and do not require thread sealant during installation. The anti-corrosion performance of steel fittings is excellent, greatly exceeding the SAE requirement of no red rust within 72 hours. The working pressure can reach 7500psi, and they are suitable for scenarios such as hydraulic fluid and gas handling connections.
Face Seal Fittings (O-ring Face Seal Fittings):
O-rings are used for sealing at the contact surface of the fitting, which can provide reliable sealing performance and prevent fluid leakage. This type of fitting is suitable for systems with high sealing requirements, such as high-pressure hydraulic systems, the aerospace field, etc.
Flange Fittings:
They are usually used to connect pipes or equipment with a relatively large diameter and have high connection strength and stability. Flange fittings can withstand large tensile forces, pressures, and bending moments and are suitable for some heavy industrial equipment and large pipeline systems.
In general, Parker's pipe fittings and connectors are rich in variety, can meet the needs of different industries and different application scenarios, and their products have the characteristics of high quality, high performance, and high reliability.
