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.
◎ Design Standard: API6D, ASME B16.34, BS6364, GB/T 24925, etc.
◎ Material: Carbon steel, Stainless steel, Alloy steel
◎ Nominal Size: 2"~24"DN50~600
◎ Nominal Pressure: CLASS150LB~1500LB PN10~PN250
◎ Applicable Temperature: -196℃~120℃
◎ Operation Mode: manual, worm, pneumatic, electric, etc.
◎ 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.
The Double Eccentric Butterfly Valve is a is a is a newly developed long-life, energy-saving butterfly valve by our company. It consists of main components such as the valve body, butterfly disc, sealing ring, and transmission mechanism. Its structure is designed based on the two-dimensional or three-dimensional eccentric principle and features a new manufacturing process that accommodates both elastic and multi-layer hard-soft seals. This design reduces torque during operation, achieving energy efficiency and labor-saving benefits. At the same time, it ensures the valve's overall reliability in corrosion resistance, high temperature tolerance, and wear resistance. Common types of hard-sealed butterfly valves include wafer type, lug type, and flanged type butterfly valves.
When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
The Bellows Seal Gate Valve is a high-performance valve designed to ensure sealing integrity and prevent medium leakage. It utilizes bellows seal technology to effectively block fluid leaks that could cause environmental pollution or safety hazards. This valve is suitable for use in steam, thermal oil systems, heat exchangers, and other high-temperature, high-pressure fluid control applications. Its compact structure and easy maintenance offer long-term reliable sealing performance.
