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.
Developed with: principles of standardization, universality, modularity, and interchangeability. Valves of different sizes maximize part
interchangeability, universality, and ease of maintenance. This ensures low operational costs. They can be made into special structures such as:
the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve.

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 self-regulating control valve is an energy-saving control device that does not require external driving energy. It relies on the pressure or temperature of the medium being regulated as its power source, automatically adjusting according to set values based on changes in the medium. This valve integrates multiple functions of detection and control into one unit, forming an independent instrument control system. The self-operated control valve adopts a standard modular design. Our products are characterized by: standardization, serialization, and generalization. This achieves a high level of these three aspects.
The structure adopts a short pattern, the valve gate is light in weight, and the pipe support frame can be saved. Diversified Drive Modes: Electric, gearbox, hydraulic and pneumaticcan be selected at will. High performance sealing combination packing: The combined packing sealing system isadopted to greatly improve its sealing performance.
