■Standards Design and Manufacture: Cast steel check valve to BS 1868, ASME B16.34 and API 6D;Forged steel check valve to API 602. Inspection and Test: API 598 or API 6D. End flange dimension: ASME B16.5(for NPS≤24);ASME B16.47 series B、API 605 or ASME B16.47 series A、MSS SP-44(for NPS>24). BW end dimension: ASME B16.25. Socket-weld dimension: ASME B16.11. Face to face and end to end: ASME B16.10. Pressure-temperature ratings: ASME B16.34. Wall thickness dimension: API 600 and BS 1868.■The features of check valve Bolted Bonnet; Swing and lift disc; Metallic seating surfaces.■Body and Bonnet Connection The body and bonnet of Class150~Class900 check valves are usually with studs and nuts. And the body and bonnet of Class1500~Class2500 check valves are usually of pressurized seal design.■Body-To-Bonnet Joint Stainless steel + flexible graphite wounded gasket is used for Class150 and Class300 check valve; Stainless steel + flexible graphite wounded gasket is used for Class600 check valve, and joint gasket is also optional for Class600 check valve; Ring joint gasket is used for Class900 check valve; Pressurized seal design is used for Class1500~Class2500 check valves.■Seat For carbon steel check valve, the seat is usually forged steel. The sealing surface of the seat is spray welded with hard alloy specified by the customer. Renewable threaded seat is used for NPS≤10 check valves, and welded on seat can be also optional if being requested by the customer. Welded on seat is used for NPS ≥12 carbon steel gate valves. For stainless steel check valve, integral seat is usually adopted, or to weld hard alloy directly integrally. Threaded or welded on seat is also optional for stainless steel check valve if being requested by the customer.

Check valve installed in the piping system, and its main role is to prevent the media back, A check valve is opened to rely on media pressure and the closure of the automatic valve. Widely used in Taiwan is H44 - flange connecting Kai Xuan - H41-check valve and flange connecting movements valve This traditional bulky big check valves, fluid resistance, the valve closes when the water hammer pressure, installation, maintenance difficulties, short service life. I companies check valve against the traditional structure of the issue, the United States and Germany API standard DIN standards as the basis, I combined company over the years valve test research, development design, processing and manufacturing, and other aspects of rich experience, Development of the H76-to-flap folder rotary valve and Kai-H71-to-folder lifts valve series products, by the petrochemical, metallurgical, power, light industry, food industry enterprises and manufacturers of complete sets of equipment used for years, the result is good, was well received by users. Products by the provincial science and technology achievement appraisal, technical innovation, leading to the domestic level. China is the fourth and new technologies and products Expo in Kuala Lumpur, was recommended for high-quality IT products in Zhejiang province. I am responsible for the drafting of the national machinery industry standards JB/T 8937-1999 "folder valve" in the whole State promulgation and implementation of new technologies for the promotion and application of the industry and to the technological progress made positive contributions. Characteristics of a structure, the structure of the short length, the length of the structure is only the check valve flange traditional 1/4~1/8; 2, The small size, light weight, the weight only to the traditional check valve flange 1/4~1/20; 3, valve valve fast, Small water hammer pressure; 4, horizontal or vertical pipe can be used by pipeline, easy installation; 5, the flow smooth, fluid resistance is small; 6, movement sensitive and good sealing performance; 7, a short trip flap valve, valve clearance impact small; 8, the overall structure, a simple compact, Modeling beauty; 9, long life and high reliability. Use of his spin-valve Kai apply to seating PN1.0MPa~42.0MPa. Class150~2500; public Path DN15~1200mm said. NPS1/2~48; -196~540 ° C operating temperature of the road for the media to prevent backflow. Through the use of different materials and can be applied to water, steam, oil, nitric acid, acetic acid, a strong oxidizing media and urea, and other media.
