Since hundred years before, valves products which related to oil, gas development and transmission has basically nothing changed, but the valves manufacturer has been constantly updated valves technology, actively responded to changes of the oil and gas industry market.

1) The world market of metal seal has a rapid growth demand for oil and gas, the footprints of developping crude oil has throughout every corner of the earth, crude oil extraction put forward a new reqiurement of equipment

2) "Anti-explosion decompression". 2002, conform to American petroleum institute API6D standard: Design pressure of valves products which is higher than ASMEClass600 must be designed "Anti-explosion decompression".

3) Early wear and equipment fatigue. For the pursuit of economic interests, many refinery enterprises are overloaded. The result is endlessly compatibilizing production equipment and transformation system.

4) In order to ensure production, preventive maintenance petroleum enterprises require to schedule equipment maintenance period.

5) Automation is the trend of the automatic actuators refining process, its control technology has developed for quite a long time.

6) Pipeline ball valves. Gas transport engineering is a very large and potential market to the valves.

7) Corrosion of sulfur crude oil. Because the price of crude oil got higher and higher, so oil company focused on the sulfur crude oil, investment and development of sulfur crude oil have a lucrative market profits and a competitive price advantage in long-term supply contract.

8) Fly emissions. ISO15848 set the design reqirements of fly emissions to the valve, manufacturers redesigned the packing, seal arrange of common valves and special valves in order to adapt to the renewal standard. But the new standard is too generalized and the request is too strict, so there are many petroleum enterprises to set their own emissions standards, for example, many North America companies conform to the API622 standard.
