SASPG Chengdu Valve Co.,Ltd,Affiliated to Sichuan Air Separation Plant(Group)Co.,Ltd ,is professionalized in the design and fabrication of all kinds of valves,which are widely used in air separation plants,petroleum and natural gas liquefaction plants,chemical tail gas equipment,cryogenic storage tanks and tankers for liquid oxygen,nitrogen,argon,hydrogen & carbon dioxide,PSA plants,PSA hydrogen recovery plants,carbon dioxide plants,acetylene plants and power stations.Now,we can produce over ten thousand types of valves,including butterfly valves,ball valves,shutoff valves,throttle valves,check valves,pressure-reducing valves,safety valves,cryogenic breather valves with large diameters,three-way switch-over valves and liquid level gauges,etc.Tha maximum valve diameter can reach 1200mm,the maximum pressure up to 35MPa,the lowest temperature -253 oC while the highest temperature +850 oC.The valves can be operated manually ,pneumatically,electro pneumatically& fully electronically.The materials for most of the valves used in the cryogenic equipment,natural liquefaction & separation plants,petrol & chemical projects & power stations are stainless steel,copper alloy,aluminum alloy and the high-temperature alloy used in the aerospace field.
&＃12288;&＃12288;We can provide the quality valves for oxygen plants as per the ASME Code & AP16D Standard,among which the pneumatic butterfly valves of 101D series were awarded "Gold Prize" in 1993 at the ALL-China Youth Science & Technology Fair.This series of butterfly valves have been widely used in the metallurgical & chemical industries and have replaced the imported butterfly valves.
