The world control valve market will amount to USDs 3,500,000,000 in 2007

Though current world control valve market indetermination, and have the decline, the profession high class analyst points out to control the valve prospect target is clear and definite, there is food processing, beverage in related development inside market, disinfect the article particularly the chemistry product keeps the high speed increases.Although traditional market, for example the chemical engineering keeps on with the deckle the reduces, the energy face the new investment with natural gas factory face to face, reform with modernize to replace, along with world petroleum price with the rise that refinement equip, control valve need will last to increase.
According to investigate the analysis, world control in the scope valve market, measures in the 2002 gross to near to 6,500,000,000 anticipate to will attain at the end of till 2007 35 the US$ of hundred million, the year average increases 3%.

API6Fa / API607 fire of ball valve fireproof test

CHAODA achieved the API 6Fa fireproof test and API 607 fire of big size ball valve fireproof test

CHAODA has achieved the ISO 9001 Certificate in 1998, API 6D Certificate in 1999, CE Certification in 2002, the first domestic enterprise that gained the API 600 Certification in 2003,A PI 607 Fireproof Test Certification and AZ safety certificate in 2004 and TUV API 6Fa and API 607 Certificate for big size ball valve fireproof test in May 10th 2006.

Valve

1. Thermocouple

1) There mustn’t be any damage or peeling off for the cover of insulation wire or insulation sleeve, otherwise it will cause short circuit, which will influence the normal operation of the valve.
2) The fix-up of the thermocouple must dissipate heat to reduce the heat accumulation of fixing board and thermocouple copper. This can shorten the valve-closing time when there is sudden flameout.
3) The heated part of a thermocouple must be on the top of 2-3mm. Not to put the top into the fire, otherwise it may reduce the potential and shorten its life.

2. Solenoid valve

1) Prevent the valve from being strongly striken in the process of installation and shipment, otherwise it may influence its normal performance.
2) Before installation, the user must check the valve flatly on the test clamps with some prepressing. It is not allowed to be freely-flip. This assures that magnetic material won’t be damaged by colliding, otherwise it will influence the magnetic force.
3) Clean the impurity such as aluminum or oil left on the inner wall of the stove and the surface of the valve.
4) Keep the good connection of the solenoid valve and thermocouple. Prevent the safety protection device from operating abnormally because of too big contact resistance.
5) The warehouse of solenoid valves must be dry and ventilated and strictly prohibit extrusion.
