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
Stainless steel bellows pressure-balancing type, with small unbalanced force and high sensitivity
Supports internal and external pressure tapping
Wide range of set points, adjustable set points can be conveniently adjusted by adjusting the nut
For high sealing requirements, use soft-sealing valve core

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.
The Rotary Ball Valve adopts advanced ball rotation sealing technology and is specially designed for harsh working conditions. It is suitable for the control of high-pressure, high-temperature and corrosive media in industries such as petroleum, chemical engineering, natural gas, and power. Its unique rotating valve seat structure effectively reduces friction and wear, ensuring more durable sealing performance and easier operation. The valve body is made of high-quality stainless steel, carbon steel or special alloy materials, and is precisely processed and hardened to ensure long-term stable operation. It supports various driving methods such as manual, pneumatic, and electric, meeting different automation requirements and is an ideal choice for industrial pipeline fluid control.
The cryogenic butterfly body can be provided in twostructural forms, namely flange connection and butt.welding connection (both with inspection ports). The body with inspection ports can replace the valveinternals online, making maintenance work extremelysimple, which is conducive to the rational use ofresourcesand saving maintenance costs.The extended valve cover + drip tray design ensures thatthe temperature at the stuffing box is above zero degrees!so that the connection between the stuffing and the stemwill not freeze and lock.
The Top Entry Cryogenic Floating Ball Valve is a valve suitable for ultra-low temperature environments, mainly used to connect or cut off low-temperature media.
