2022/10/21 9:30:24Generally speaking, the temperature of the working environment of the low temperature valve is very low, generally between minus 40 degrees and minus 200 degrees. Therefore, compared with other traditional types of valve products, the application environment of the low temperature valve is relatively special. 2022/10/21 9:29:38In fact, all kinds of pipeline systems exist under our feet in the city, and these pipeline systems transport all kinds of energy supply to our city needs, including natural gas, gas, water, oil and other media, which are the necessary resources of the city. 2022/10/21 9:28:49The piston type electro-hydraulic valve consists of a two usually open solenoid valve, a two usually closed solenoid valve, 2 3/8 "ball valve (needle valve) combination, usually open solenoid valve is installed in the upstream pipeline of the control loop, normally closed solenoid valve is installed in the downstream pipeline of the control loop. 2022/10/21 9:27:57Clean pipes and valves before installation to remove impurities and grease. Especially when oil is forbidden, users can put forward specific cleanliness requirements. Choose lubricant, must consider the working medium taboo, to avoid the occurrence of accidents.
2022/10/21 9:26:28Multifunctional electro-hydraulic valve structure principle, shape and connection size 2014/8/8 13:39:35Before installation, the new pipeline (connected with a short pipe) shall be cleaned repeatedly to remove welding slag, welding head and other sundries, so as to avoid damaging the valve sealing surface and affecting the use.
