Advantages and features of cut-off valves

Cut-off valves are all played to quickly cut off function, with simple structure, sensitive response, reliable action, and other characteristics. It has many characteristics and advantages and can be widely used in petroleum, chemical, metallurgical, and other industrial production sectors. Today we introduce the advantages and characteristics of the cut-off valve, as well as an overview of it.

Overview

Cut-off valves are also known as globe valves. It is a kind of actuator in the automation system. The cut-off valve can receive a signal to adjust the instrument. The cut-off, switching, or switching of fluids within the process piping is then controlled. It has the characteristics of a simple structure, sensitive response, and reliable action. Cut-off valves are widely used in petroleum, chemical, metallurgical, and other industrial production sectors. The air source of the cut-off valve requires filtered compressed air, and the medium flowing through the valve body should be liquids and gases free of impurities and particles.

Features of cut-off valves

1. Cut-off valve gear type double piston, large output torque, small size, easy to carry.

2. The cylinder is made of aluminum and gold material, which is light in weight and beautiful in appearance;

3. Manual operation mechanisms can be installed on the top and bottom; There are a variety of operation methods, which can meet the habits of many people, which is very convenient.

4. The rack connection of the cut-off valve can adjust the opening angle and rated flow;

5. The actuator of the cut-off valve can choose with electrical signal feedback indication and various accessories to realize automatic operation;

6. The valve core can be made to use a single seat or sleeve to meet the cut-off requirements under different pressure differences. Pneumatic piston actuators with high thrust or electric actuators are available

Advantages of cut-off valves

1. The cut-off valve adopts a multi-spring actuator and the adjustment mechanism is connected with three columns, the overall height can be reduced by about 30%, and the weight can be reduced by about 30%;

2. The valve body is designed into an equal-section low-flow blocking flow channel according to the principle of fluid mechanics, and the rated flow coefficient is increased by 30%;

3. There are two kinds of sealing parts of valve internals: tight type and soft seal, the tight type is surfacing cemented carbide, and the soft seal type is made of soft material, and the sealing performance is excellent when closing;

5. The balanced valve trim improves the allowable pressure difference of the cut-off valve;

6. The bellows sealing type forms a complete seal on the moving valve stem, blocking the possibility of medium leakage;

7. The cut-off valve is a piston actuator with a large operating force and large pressure difference.

Above we have introduced the cut-off valve. Include its overview, features, and benefits.
