Uhlelo lwamakhilomitha lwezindlela zomthombo lwasungulwa ekuthuthukiseni kwesoko elingaphansi kakhulu.

Ngo iminyaka eminingi ngokwesiko, ngesivinini se-mechatronics, izivalo zezinkanyezi, isakhiwo esikhulu se-mechanical sibonakala ekuthuthukiseni kwesithakazelo esingaphansi. Izivalo zezinkanyezi kunezivalo ezimbalwa (izivalo zomsebenzi, izivalo zomoya) ekusebenziseni kuyathuthukisa, kuyathokozisa futhi kuyalinganisela. Ngesimo semvelo nokuthuthukiswa kwesafety okwamanje okhomba okuphambene, izivalo zezinkanyezi zingaba ngempela. Isidingo esikhulu sasezindaweni zezinkanyezi kuyadinga kakhulu. Amadivayisi ezinkanyezi azimele, azigcina, azinikeza izidingo zezindawo eziningi, ezihlukene, ezihlukene, ezihlukene, ezihlukene, ezihlukene, ezihlukene, ezihlukene, ezihlukene, ezihlukene,

In addition, the motor-driven way to open and close the smoother, without the shortcomings of the instantaneous impulse is too large, the failure rate can be greatly reduced. The petrochemical industry mainly adopts API standard gate, globe and check valves; the power sector mainly adopts high-temperature pressure gate, globe, check and safety valves for power stations and a part of low-pressure butterfly valves and gate valves for water supply and drainage valves; the chemical industry mainly adopts stainless steel gate, globe and check valves. Metallurgical industry mainly uses low-pressure large diameter butterfly valves, oxygen globe valves and oxygen ball valves; urban construction sector mainly uses low-pressure valves, such as urban water mains mainly used in large-diameter gate valves, building construction mainly used in the middle of the line butterfly valves, urban heating mainly used in the metal-sealed butterfly valves, etc.; oil pipeline mainly used flat gate valves and ball valves; pharmaceutical industry mainly used in the stainless steel ball valves; the food industry mainly uses Stainless steel ball valves are mainly used in the pharmaceutical industry; the food industry mainly uses stainless steel ball valves.

Electric valve is a new species of valve industry, so the market prospects of electric valve is very broad, casting enterprises should learn more about this industry, to provide casting parts for this industry to electric valve this emerging industry to drive the development of casting industry in order to obtain new development momentum. With the transformation of the market towards the electric valve products also change accordingly. For example, with the transfer of oil development to the mainland oil fields and offshore oil fields, as well as the power industry from 300,000 kilowatts of thermal power to more than 300,000 kilowatts of thermal power and hydropower and nuclear power development, electric valve products should be based on the changes in the field of application of the equipment to change its performance and parameters. The urban construction system will use a large number of low-pressure electric valves, and to the environmentally friendly and energy-saving development, that is, from the past use of low-pressure iron gate valve gradually turned to the environmentally friendly rubber plate valve, balancing valve, metal-sealed butterfly valves and the transition of the centerline sealed butterfly valve, oil and gas transmission projects to the pipeline direction, which in turn requires a large number of flat plate gate valves and ball valves. Power station construction to large-scale development, so the need for large diameter and high pressure safety valves and pressure reducing valves, but also need to use fast opening and closing of electric valves; for the need for complete sets of projects, electric valves supplied by a single variety of varieties and specifications of the development of multiple varieties. A project required by the electric valve, by an electric valve manufacturer to provide all the trend is growing.

Isiphetho esisha somkhomba welekhithi ngezidingo zokuthuthukiswa kwemfundo nokwemisebenzi emakethe, kuyiyo ekwakhiweni kwemvelo yezemfundo, izici eziningi, ukunakekelwa okukhulu, ukukhanya kokuphila okuphezulu.
