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. Sensitive action, good sealing performance; Open and close quickly. The overall structure: simple and compact, beautiful shape, low cost for throttling compared to regulating valve. Long service life and high reliability.
Application Scenario: The throttle stop valve is generally used on the pipelines where the flow resistance requirements are not strict and the regulatory flow requirements are not high. For example, a high-temperature and high-pressure working medium, toxic and harmful dangerous liquids, the
closure of closure must ensure long-term sealing, leakage and inaccurate regulating flow. 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 DBB Ball Valve (Twin Ball) requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
RAYS Side Entry Floating Ball Valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute Standard API 608&API 6D British standard BS 5351 and generally conform to American Society of Mechanical engineers standard ASME B16.34 valves are available in a complete range of body/bonnet materials and trims.
Side Entry Cryogenic Trunnion Mounted Ball Valve and extended valve cap ball valves will bring you huge profits in the field of low-temperature LNG services. Use temperature range-196°C~+150°C, with an extended valve cover design.
