Parker Hannifin, also known as Parker Hannifin in Chinese, is a leading diversified manufacturer of motion and control technology and systems, providing precise solutions for a wide range of transmission control, industrial, and aviation markets. It has now become a global ZUIA large professional company that produces and sells various refrigeration and air conditioning components, hydraulic, pneumatic, and fluid control products, as well as electronic components. Parker Hannifin has been in China for over 20 years, and in 1990, Parker Hannifin established its first company in China. There are currently six, located in Shanghai, Beijing, Guangzhou, and Hong Kong. The Asia Pacific headquarters was established in Hong Kong in 1994. In 2000, a wholly-owned spot company was established in Jinqiao, serving as the headquarters for the China region, namely Parker Hannifin Management (Shanghai) Co., Ltd., responsible for the overall management of Parker Hannifin in China. Parker Hannifin Fluid Transmission Products (Shanghai) Co., Ltd., as a sales company, engages in and develops Parker China's business activities. In addition, Parker also has many subsidiary brands, such as the famous Sun Company, the famous Leclery from France, TEMA Tianma connectors from Germany, RECETUS quick connect from Germany, Dominique Hande from the UK, and Balston from the US, all of which have become subsidiaries of Parker Hannifin. At the end of March 2012, Parker had just completed the comprehensive acquisition of Snap Tite, bringing a well-known American manufacturer of connectors and disconnect valves under its umbrella.

PARKER proportional valve is a new type of hydraulic control device. On ordinary pressure valves, flow valves, and directional valves, proportional electromagnets are used instead of the original control parts to continuously and proportionally control the pressure, flow rate, or direction of oil flow remotely based on the input electrical signal. Proportional valves generally have pressure compensation performance, and the output pressure and flow rate can be unaffected by load changes.

Working principle of PARKER proportional valve

The command signal is amplified by a proportional amplifier and outputs current proportionally to the proportional solenoid of the proportional valve. The proportional solenoid outputs force and moves the valve core position proportionally, which can control the flow rate and change the direction of the liquid flow proportionally, thereby achieving position or speed control of the actuator. In some applications that require high precision in position or velocity, a closed-loop control system can also be formed by detecting the displacement or velocity of the actuator. The proportional valve consists of two parts: a DC proportional solenoid and a hydraulic valve. The core of continuous control of the proportional valve is the use of proportional solenoid. There are many types of proportional solenoid, but their working principles are basically the same. They are all developed according to the control needs of the proportional valve.

PARKER proportional valve control valve is a type of control valve that continuously and proportionally controls the flow, pressure, and direction of hydraulic systems based on input electrical signals. Its output flow and pressure can be unaffected by load changes.

Compared with ordinary hydraulic components, proportional valves have the following characteristics:

(1) Electrical signals are easy to transmit and can be easily controlled over long distances.

(2) It can continuously and proportionally control the pressure and flow of the hydraulic system, achieve control over the position, speed, and force of the actuator, and reduce the impact during pressure changes.

(3) Reduced the number of components and simplified the oil circuit.

At the same time, the usage conditions and maintenance of electro-hydraulic proportional valves are the same as those of general hydraulic components, and they have stronger anti pollution performance and reliable operation than servo valves.
