Flow Control Usage Stainless Steel Control Knife Gate Valves for Pulp Factory

Product Description

Product Description

Control valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their types, they can be divided into Ball Valves, Check Valves, Regulating Valves, Butterfly Valves, Gate Valves, Globe Valves, and Pressure Reducing Valves.
The products are widely used in the automatic control systems of industrial sectors such as chemical, petroleum, chemical fiber, electricity, metallurgy, pharmaceutical, papermaking, and environmental protection.

Ball Valves

The ball valve controls the flow of fluid by rotating the ball inside. There is a hole on the ball. When the hole is aligned with the axis of the pipe, the fluid can pass smoothly; when the ball is rotated 90 degrees so that the hole is perpendicular to the axis of the pipe, the fluid is completely cut off. The ball valve is suitable for medium to high pressure systems and has the characteristics of compact structure, flexible operation and low fluid resistance.

Butterfly Valves

The butterfly valve controls the flow of fluid by rotating the disc-shaped valve disc. It has a simple structure, flexible operation, and small space occupation, and is suitable for situations where frequent operation is required or space is limited. The sealing performance of the butterfly valve is relatively weak, especially in high temperature or high pressure environments, but its fluid resistance is small and the operation is labor-saving.

 

Gate Valves

The gate valve blocks the flow of media by making the highly smooth and even gate sealing surface fit with the valve seat sealing surface. The gate valve is suitable for bidirectional flow of media, has the characteristics of low fluid resistance and easy opening and closing, and is suitable for the needs of large valves.

 

Check Valves and Globe Valves

The check valve is also called a one-way valve or a non-return valve. Its function is to prevent the medium in the pipeline from flowing back. Check valve has a simple structure and is mainly used to ensure the one-way flow of the medium.
The Globe Belongs to the category of "shut-off valves". Globe valves are used to cut off or connect fluids. They usually have good flow regulation functions, but their main function is switch control.

Regulating Valves

The regulating valve precisely adjusts the position of the valve disc through the operation of the actuator to control the flow, pressure and temperature of the fluid. The regulating valve is suitable for various systems from low pressure to high pressure and has the function of precise regulation.

Pressure level:	PN16-PN160
Valve size:	DN15~DN400
Leakage level:	ANSI /FCI 70-2 Level IV (standard); Level V, Level VI (optional)
Operating temperature	-196°C ~ +530°C
Flow characteristics:	equal percentage, linear
Valve flow direction:	low inlet, high outlet

 

Pressure Reducing Valves

The pressure reducing valve is used to reduce the higher fluid pressure to the required pressure range. It is usually used in gas pipeline systems to ensure the normal operation of downstream equipment.
