Gate valve at the both ends and needle valve of the dual-connected samplie gate valve retain the advantages of
general gate valve and needle valve. When sampling, the medium pressure of the sampling port can be
rationally selected according to different requirements, and the safety is higher. The valve body adopts the
integrated design, the layout of double gate valve, needle valve and sampling port is reasonable, the structure is
compact, and the installation space does not need to be too large. The sampling port can replace the role of
sewage of pipelines when installing. The medium can flow in any direction on both sides and easy to install.
◎ Design Standard: API602, ASME B16.34
◎ Main Material: Carbon Steel, Stainless Steel, Alloy Steel, Etc.
◎ Size Range: NPS1/2~NPS10/DN15~DN250
◎ Pressure Level: Class150~ Class 2500/PN20~PN420
◎ Temperature Range: -29℃~650℃
◎ Application Scenario: The dual-connected sample gate valve is used in the occasion that the sealing effect is relatively strict and requires the control medium composition (sampling verification). For example, a high-temperature and high-pressure working medium, toxic and harmful risk liquid, the closure of the closure must ensure long-term sealing and leakage (the double gates valve can achieve a double-level seal effect under non-sampling state). 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 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.
RAYS C-type ball valve adopts a double eccentric design: the rotational center (axis) of the C-ball is offset from both the geometric center (sphere) of the C-ball sealing surface and the sealing center of the seat. This double eccentric design results in a dual-vector cam motion involving both rotation and translation of the C-ball, facilitated by the stem being offset in two planes. When the valve is closed, the C-ball and the seat interact to create a cam-action wedge tightness, achieving a torque seal. The torque required for sealing is provided by a handle, gear, or actuator, ensuring a tight shut-off that is mechanically independent of springs or process pressure
RAYS Metal Seated Wear-Resistant Ball Valve is designed for extreme conditions characterized by high temperatures, high pressures, and abrasive media. Manufactured from premium alloy steel and enhanced with advanced hardening techniques, it offers exceptional wear resistance for both the ball and the seat. The hard seal design ensures superior sealing performance in harsh environments. Additionally, the valve features a robust construction and is easy to operate and maintain, significantly reducing maintenance costs. It is an ideal choice for heavy industries such as petrochemicals, power generation, and mining.
