During the opening and closing process, the friction between the valve petals and the cover surface is small and wear-resistant. The itinerary height
is relatively small. The action is sensitive and the sealing performance is good; the opening is quickly closed, and the torque is light. The overall
structure, simple and compact, beautiful shape. Long service life and high reliability.
Design Standard: BS1873, API623, ASME B16.34
Main Material: Carbon Steel, Stainless Steel, Alloy Steel, Etc.
Size Range: NPS4~NPS20/DN100~DN500
Pressure Level: Class150~ Class 2500/PN20~PN420
Temperature Range: -29℃~540℃
Application Scenario: The globe valve is generally used on the pipelines that are not strict with the flow resistance on the pipeline, that is, the place where the pressure loss is not large. For example, a high-temperature and high pressure working medium, toxic and harmful risk liquids require
closure to ensure long-term sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the
application of power industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry
and other fields.
The Side Entry Cryogenic Floating Ball Valve is specially designed for deep cryogenic media (such as LNG, liquid nitrogen, liquid oxygen, etc.) applications. It adopts a unique side-mounted structure to ensure stable operation in extreme low-temperature environments below -196°C~+150°C. The valve body is made of high-quality stainless steel or special alloy materials, combined with precise processing techniques, achieving zero leakage and long service life under ultra-low temperature conditions. It is widely used in liquefied natural gas, air separation equipment, chemical and energy fields, and is a reliable choice for fluid control in harsh conditions.
The power station swing check valve is mainly suitable for the pipelines of the various systems of thermal power station to prevent the medium from flowing. Compared with other valve products, the power station swing check valve-outbound valve is high -temperature and high pressure. It is a unique and tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The power station swing check valve -type stop valve has the design characteristics of ordinary spinning -type stopping valve. The valve petals rely on the flow of the medium to open and close the valve. Because the valve petals do not rub with the valve seat before closed, the cover wear is reduced to effectively extend the service life of the valve.
The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
