C-type Structure: The valve body of the C-type ball valve is designed to be similar to the shape of the English letter "C". This design helps to reduce fluid turbulence and pressure loss, while facilitating cleaning and maintenance.
Top-loading Design: The main components such as the ball and valve seat can be removed and installed from the top of the valve body,
which is convenient for maintenance and replacement without removing the pipeline.
Fixed Ball Design: The ball is fixed in the valve body and does not rotate with the flow of fluid, which helps to reduce the erosion of the ball by the fluid and extend the service life of the valve.
Ultra-low Temperature Materials: The valve is made of stainless steel, nickel-based alloy and other materials suitable for ultra-low
temperature environments, and uses sealing materials with good low temperature performance, such as PCTFE.
Thermal Insulation: The valve may be equipped with a thermal insulation layer to prevent external heat from entering the fluid and maintain
the fluid at an ultra-low temperature.

◎ Scope of Application: Top entry cryogenic C-type ball valve is widely used in air separation equipment, oxygen generator, liquid nitrogen, liquid
oxygen, CNG, LNG and other industrial sectors. It is suitable for ultra-low temperature occasions that require precise control of fluid flow, pressure
and direction.
Compared with other valve products, HTHP Slab Gate Valve is characterized by high temperature and high pressure. Among them, grooved flange is designed as a unique self-tight-seal 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 high-temperature and high-pressure 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 sealing surface of the valve seat is accurate accordingly. 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.
The low-temperature single-seat regulating valve is specially designed for low-temperature working conditions ranging from -196℃ to +80℃. It features an integral forged valve body structure and is equipped with a bellows seal assembly to ensure reliable sealing under extreme temperature conditions. The valve core is designed with a parabolic or equal percentage flow characteristic, forming a precise fit with the hardened alloy valve seat to achieve precise control of the medium flow. The product complies with IEC 60534-4 and GB/T 4213 standards, and is suitable for precise regulation of low-temperature media such as LNG, liquid oxygen, and liquid nitrogen. The pressure rating covers ANSI Class 150 to 900, and is widely used in key areas such as air separation equipment and low-temperature storage and transportation systems.
HTHP Wear-Resistant Ball Valves are special valves designed for high temperature and high pressure environments, which can effectively control the on/off of high temperature and high pressure fluids. Capable of stable operation under harsh working conditions, meeting the precise control requirements in industrial production processes. Widely used in industries such as petroleum, chemical, natural gas, and electricity.
