SO-26001、SO-26101、SO-26201 Self-operated Differential Pressure Regulator for Downstream Control
An energy-saving control valve without external energy supply, used for non-corrosive liquids and gases with a temperature of ≤ 200℃. It is a pressure differential control device at the valve outlet. When the pressure differential increases, the valve closes.
SO-26002、SO-26102、SO-26202 Self-operated Differential Pressure Regulator for Upstream Control
An energy-saving control valve without external energy sources, used for non-corrosive liquids and gases with a temperature of ≤ 200℃ and a valve-before differential pressure control device. The valve opens when the differential pressure increases.
An energy-saving control valve without external energy supply, used for non-corrosive liquids and gases with a temperature of ≤ 200℃ for differential pressure control devices. The valve opens or closes when the differential pressure increases.
Low maintenance, direct control of the medium, energy-saving control valve without external energy supply

Application range: This is applicable to automatic control systems without (or where driving energy cannot be used) in industrial processes such as water supply, petrochemicals, heating and thermal supply, energy, papermaking, food, and steel production. It is particularly suitable for automatic control system devices in natural gas extraction and transportation or gas transmission.
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 Power Plant Gate Valve is mainly suitable for the pipelines of various systems of thermal power station, cutting or connecting the pipeline medium. Compared with other valve products, the Power Plant Gate Valve is characterized by high temperature and high pressure. It is counted as a unique and closely sealed 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 Plant Gate Valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the seal of the gate on the valve seat is correspondingly accurate. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
RAYS pig valve is a high-performance ball valve designed for severe industrial environments, featuring multifunctionality aimed at optimizing pipeline cleaning and maintenance. This valve facilitates the movement of pipeline pigs to effectively remove scale, deposits, and other impurities, maintaining cleanliness and flow efficiency in pipelines.
