Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes. Ultra-low temperature regulating valve: CUT701 Cryogenic temperature control valve is a top-guided structure that is designed for use at ultra-low temperatures (-196℃). All components of the valve have undergone special design and low-temperature process treatment, which can meet the usage requirements of various special working conditions. The core parts can be replaced online. Its structure is compact and the design is reasonable. The long-necked valve cover with insulation can make the valve stem sealing area work close to normal temperature. Reduce the transfer of external heat to ensure the reliable operation of the valve under ultra-low temperature conditions.
● Cryogenic temperature regulating valve:
● Adopting elongated valve cover to prevent cold conduction and freezing of packing, thereby eliminating the adverse impact of ultra-low temperature on the sealing performance of the stuffing box;
● Main components undergo hardening treatment, ultra-low temperature treatment, and ultra-precision processing to ensure precise regulation of flow and pressure.
● Passed strict ultra-low temperature deep cryogenic tests to guarantee stable operation under extreme conditions, ensuring safety and reliability.

Triple Eccentric Metal Seated Butterfly Valve is the newly-developed long-life and energy-saving products. The sealing is metal to metal, which couldbe changed to be seal ring to metal, stainless steel plate and composite graphite to metal. Under the working condition of high temperature and high pressure, it still has a stable sealing performance. Our company adopts optimization design and new technology, so that the torque is small, gainning the point of energy-saving, labor-saving and reliable sealing performance, thus to ensure the high-reliability of corrosion-resistantance, stand fire and wear-resistantance. This product is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental water treatment and shipping industry.
The Power Station 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 station 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 station 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.
Self-acting Temperature Control Valve is an energy-saving control device that does not require external driving energy. It relies on the temperature of the medium being regulated as the power source and the changes in the medium to automatically adjust according to the preset value. It integrates detection, control and execution functions into one valve and forms an independent instrument control system.
