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.
Material: Stainless Steel, Alloy Steel
Nominal Size: NPS 1/2"~24", DN 15~600
Pressure Rate: Class 150~2500, PN 10~420
Temperature Range: -196°C~+150°C
Operator: Manual, Pneumatic, Electric, etc...
Application Range: LNG, LPG, LNG low temperature conditions and long-distance pipelines such as oil, gas, and natural gas.
The valve body is made of high-strength alloy steel or stainless steel, and is equipped with a precisely processed swing-type valve disc structure, enabling automatic control of the unidirectional flow of the medium. The optimized fluid dynamics design effectively reduces water hammer impact. The surface of the valve disc is clad with hard alloy to ensure reliable sealing under high-pressure and high-speed conditions. It is suitable for pipeline systems in industries such as petroleum, chemical engineering, and power.
C700 Series Single Seated Control Valve is a top-guided structure control valve, used in equipment that can achieve air opening or air closing. The fluid channel of the valve body is in an S-shaped streamlined shape, featuring low pressure drop loss, large flow rate, wide adjustable range, high accuracy of the flow characteristic curve, large guiding area of the valve core, and good vibration resistance. The control valve is equipped with a multi-spring diaphragm actuator, which features a compact structure and large output force. It can be used to control various fluids with different pressures and temperatures.
Our company has developed a variety of series of Angle control valves. They feature a compact valve body structure, low pressure drop loss, large flow rate, unobstructed flow channel with low resistance within the adjustable range, and high accuracy of the flow curve. It is particularly suitable for regulating high-viscosity fluids containing suspended solids and granular materials, which can prevent coking, adhesion, clogging and other phenomena, and is convenient for self-cleaning and cleaning. The control valve is equipped with the RSMF type multi-spring pneumatic diaphragm actuator, which features a simple and firm structure, large output force and long service life.
