Talking about the Adjustment Performance of Pneumatic Actuator and Electro-hydraulic Actuator

Since the air is compressible, the stability of the pneumatic transmission system is poor, which has a great impact on the accuracy of position control and speed control. Therefore, the positioning signal of the pneumatic actuator usually produces an execution error with a resolution of about 3~5%. This leads to inaccurate valve positioning correction, the valve should be closed but not closed, and at the same time, it cannot be positioned due to the execution error caused by the resolution,



What should be paid attention to in the valve

In industries that require temperature, high and low temperature cycle temperature control system equipment has been widely used, which can realize two functions of heating and cooling. During cooling and heating, the temperature change in the thermostat can be realized by the circulation of the fluid medium (refrigerant), so as to achieve the temperature required by the process. 1. What is the function of the valve of the high and low temperature cycle temperature control



Chemical industry

The chemical industry is a large polluter because of its various types, complex processes, and diverse products, and the types, quantities and toxicity of pollutants discharged during production.

Oil and gas

With the increasing demand for oil and gas products around the world and the depletion of oil and gas resources, the collection, transportation and processing technology and requirements of oil and gas products become increasingly complex, costly and face more and more personalized technical requirements

Pharmaceutical industry

Pharmaceutical industry is an important part of China's national economy. It is a combination of traditional industry and modern industry, and one, two and three industries are integrated.

Metallurgical Industry

The valve used in iron metallurgy industry has strict working condition, poor sealing performance of valve, wear problem in production engineering causes pipeline aging and valve damage, which needs frequent maintenance and treatment. Therefore, due to the problems of short service life and high maintenance frequency of valve, it causes long shutdown time

Water treatment industry

The basic situation of water treatment industry, water resources is an important resource for human survival and social development. With the rapid development of China's economy, urbanization and industrialization process

Electric power industry

Electric power is a kind of energy which is powered by electric energy.Invented in the 1870s, the invention and application of electricity set off the second wave of industrialization
