The Axial Flow Control Valve is a high-performance control valve featuring an advanced structural design. Its straight-through streamlined flow path allows the throttling element to align with the direction of media flow, reducing energy loss and increasing flow capacity by approximately 20%–50%. With a low flow resistance coefficient, robust structure, low maintenance requirements, and high performance, the valve is widely used for the regulation and control of natural gas, crude oil, refined oil, and other non-corrosive gases and liquids.
• Self-balanced pressure design on the upper and lower sides of the valve plug enables tight shutoff with low actuator thrust, making it suitable for large-size and high-pressure applications.
• The valve body adopts a straight-through streamlined internal flow path, reducing flow resistance and achieving a higher Cv value.
• Sensitive operation, high-precision positioning, fast response, robust structure, long service life, compact design, and small installation footprint.

The valve body is made of high-strength alloy steel or stainless steel, and is equipped with a precisely processed swing-type valve disc structure, enabling automatic control of the unidirectional flow of the medium. The optimized fluid dynamics design effectively reduces water hammer impact. The surface of the valve disc is clad with hard alloy to ensure reliable sealing under high-pressure and high-speed conditions. It is suitable for pipeline systems in industries such as petroleum, chemical engineering, and power.
RAYS cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API600 & 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/cover materials and trims.
The globe valve is mainly composed of valve body, valve cover, valve disc, valve stem and valve stem nut. The handwheel applies a certain torque on the upper end of the valve stem, and passes the valve stem to the valve petals to move it along the valve stem axis to achieve full or full-closed motion. The force applied by the handwheel can be obsessed with the valve seat to reach the stagnation state. The two-valve petals are designed to enter the top of the medium from the cover of the valve petals. The force force of the medium is the same as the valve closure direction, so the torque of the valve closure is small; The petals, the medium enters the exit of the valve from the inside, and generates a small amount of balance of the pressure of the pressure on both ends of the valve inlet and export, thereby achieving the effect of reduced the valve opening torque. Therefore, globe valve(double disc) is mainly used in high pressure or large-caliber pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
