hydraulic fittings (A) of the energy used by different pneumatic components and devices Pneumatic gas station can be used, depending on the requirements and control points to adjust their working pressure reducing valve. Hydrau lic valve has a return line, easy to tank collection of used hydraulic oil. solenoid pneumatic valve through the exhaust port directly to the compressed air emissions to the atmosphere. (B) the leakage requirements of different hydraulic valve demanding, outward leakage of elements inside the small amount of leakage is permitted. Outside, in addition to the gap sealing the valve solenoid pneumatic valve, in principle, allow internal leakage. Pneumatic valve internal leakage there is the danger of causing the accident. For pneumatic conduit, allowing little leakage; hydraulic pipeline leak will result in the system pressure drop and the pollution of the environment. (C) lubrication requirements of the working medium of the hydraulic system for hydraulic oil, hydraulic valve does not exist on the lubrication requirements; pneumatic system of the working medium is air, air lubricity, many pneumatic valve requires oil mist lubrication. Parts of the valve should be less susceptib le to water corrosion of materials, or to take the necessary anti-rust measures. (D) the pressure range of different pneumatic valve working pressure range lower than hydraulic valve. The working pressure of the pneumatic valve is usually the 10bar within a few can be reached within 40bar. But have a high working pressure of the hydraulic valve (usually less than 50Mpa). Pneumatic valve exceeds the maximum allowable pressure. oven components Often a serious accident. (E) the use of different features, pneumatic valve hydraulic valve structure is compact, lightweight, easy to integrate installation, high operating frequency of the valve, and long service life. The pneumatic valve forward low-power, miniaturization direction, the power is only 0.5W low power solenoid valve. Can be connected directly with the computer and PLC programmable controller, together with electronic devices can also be mounted on a printed circuit board, turned on the gas-electric circuit through standard board, save a lot of wiring, applicable to the pneumatic industrial robot, complex manufacturing The assembly line and other occasions.stainless steel pneumatic cylinders
