Z43WHF dual-seal flat valve adopted in NG storage & distribution statio55n of Zhongyuan Oil Field

　　Our duel-seal flat gate valve is adopted auto seal in pressure difference and compulsory seal structure and made by new high-quality seal materials, which enhance seal reliability of products and galling resistance and prolong utilization service life. This products can be utilized in all long-distance transport network need ball hose sweeping. Inspected by state technical supervision department, its quality is complied with GB/T13927 and JB/T5298. Through utilization in Daqing oil field, Zhongyuan oil field, Changqing oil field, kelamayi oil field, it owns high reputation, especially gas and petrol gathering line network is booming, so it owns good market prospect. This product was offered national patent, and it's listed as important new product in 2000's development project .

Pressure Release Apparatus utilized in Qing-Ha crude oil pipeline

　　Our ultra-pressure release protection apparatus for fluid gathering line has declared for national patent. It's a necessary safety protection apparatus(release valve) for fluid gathering line. Tested by PLA oil transport equipment inspection center, its performance is up to the standard of foreign same products. This product is only produced in China and applied in Weizhou peninsula terminal disposal station of Nanhai, Daqing Oil Field, Southwest Product Oil Line, Ke-Wu Product Oil Line, Jingxian crude oil pipeline,ect projects with good comment. It's listed as state important new product by state science commission in 2001 and supported by technical innovation found for state S&T small-size enterprises.

　　Besides functions of normal check valves,our low-friction slow close ball check valve is also applicable for ball valve lines to benefit line cleaning device. With hydraulic amortization function , it's can be started by manual and fixed in reverse pumping. With soft,hard seal and low-pressure seal, this valve can be utilized in oil, gas and water,ect fluid gathering line.

　　High-performance seal butterfly valve is adopted metal hard seal structure,which expand the range of rated pressure of products and beyond over 1.0MPa pressure limit of normal butterfly valves using rubber seal. Our products can be applied in non-ball valve oil and gas lines. Due to small size, light weight, fast opening speed, convenient flux adjustment, compact external dimension, convenient installation,ect functions, it can be utilized widely to save materials and resources. With promotion valve, i's ideal pipes to reduce consumption

LRTH764 ball stop valve utilized in Ke-Wu Line

　　Because that there is not a proper high-quality valves to meet the demands of LPG pipeline network development. Only LPG stop valve is not enough for safety and reliability of LPG lines. We developed LPG appropriative valve which is adopted new design and made by more superior materials and rational structure to prolong its service life. This product not only guarantees safe & reliable run of LPG lines, but obtains excellent social benefits.

　　From the establishment of the company, we always emphasize high-performance, high-quality valves, and we occupy market shares by hi-tech products. We possess 157 employees, including 27 employees with various technical job titles and 16 middle and senior grade technicians with 4.03 million RMB fixed assets, full-range inspection methods for various valves. Passed ISO9001 certification, the company owns powerful quality control system to guarantee quality control in overall procedure from product design and consignation.

Pressure Release Protection Apparatus Test

　　Main leader of Kete have engaged in design, production and selling of valves for years. They are familiar with the status of valve industry. So we always take development of hi-tech products as the principal task to transfer S&T into productivity. Until now, we have developed 8 products with hi-tech content and characteristic function and step forward with 1-2 development plans. In July of 2003, Kete was certificated as Hi-tech enterprise by Chongqing Science & Technology Commission. We will cooperate with scientific research institutes to stand on a higher starting point to guarantee the company may contribute more for pipeline construction.
