8 Best Wholesale Valves suppliers In The World

Valves are piping accessories used to open and close pipelines, control flow, regulate and control parameters (temperature, pressure, and flow) of conveying media. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on.

The valve is a control part in the fluid delivery system, and has functions such as cutoff, adjustment, diversion, prevention of backflow, voltage stabilization, shunting, or overflow and pressure relief. Valves for fluid control systems range from the simplest globe valves to the various valves used in extremely complex automatic control systems.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, muds, oils, liquid metals and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, dual-phase steel valves, plastic valves, non-standard custom valves and so on.

This article will specifically introduce you to the valve information and the best website for online wholesale valve purchase.

What are the types of valves?

According to the role and purpose of the valve, the valve can be divided into the following categories:

Shut-off valve

These valves are used to open and close. Standing at the inlet and outlet of cold and heat sources, the inlet and outlet of equipment, and the branch line of the pipeline, it can also be used as a drain valve and a vent valve. Common shut-off valves are gate valves, globe valves, ball valves and butterfly valves.

Gate valves can be divided into bright and dark rods, single and double gates, wedge gates and parallel gates. The closeness of the gate valve is not good, and the large-diameter gate valve is difficult to open; the size of the valve body along the flow direction is small, the flow resistance is small, and the nominal diameter span of the gate valve is large.

The cut-off valve is divided into straight type, right-angle type and direct-current type according to the medium flow direction. There are bright and dark rods. The tightness of the shut-off valve is better than that of the gate valve. The valve body is long and the flow resistance is large. The maximum nominal diameter is DN200.

The spool of the ball valve is a round ball with an opening. The plate valve stem is fully opened when the ball opening is directly facing the axis of the pipeline, and it is fully closed when it rotates 90 °. The ball valve has a certain adjustment performance and is closed tightly.

The valve core of the butterfly valve is a circular valve plate, which can rotate along the vertical axis of the vertical pipeline axis. When the plane of the valve plate coincides with the axis of the pipe, it is fully open; when the plane of the disc is perpendicular to the axis of the pipe, it is fully closed. The butterfly valve has a small body length and small flow resistance, which is more expensive than gate and globe valves

Check valve

This type of valve is used to prevent the medium from flowing backward. It uses the kinetic energy of the fluid to open itself and closes automatically when flowing in the reverse direction. Standing at the outlet of the pump, the outlet of the trap, and other places where the fluid is not allowed to flow in the opposite direction. The check valve is divided into three types: swing-open type, lifting type and wafer type. For the swing check valve, when the fluid can only flow from left to right, it will automatically close when the flow is reversed. For a lift check valve, when the fluid flows from left to right, the valve core is lifted up to form a passage. When the flow is reversed, the valve core is pressed against the valve seat and closed. For wafer type check valve, when the fluid flows from left to right, the valve core is opened to form a passageway. When the flow is reversed, the valve core is pressed against the valve seat and closed. The wafer type check valve can have multiple positions. Installation, small size, light weight and compact structure.

Control valve

The pressure difference between the front and back of the valve is constant. When the opening degree of a common valve changes within a wide range, the flow rate does not change much, and when a certain opening degree, the flow rate changes sharply, that is, the adjustment performance is not good. The regulating valve can change the valve spool stroke according to the direction and size of the signal to change the resistance number of the valve, so as to achieve the purpose of regulating the flow of the valve. The regulating valve is divided into a manual regulating valve and an automatic regulating valve, and the manual or automatic regulating valve is divided into many types, and the regulating performance is also different. The automatic regulating valve includes a self-operating flow regulating valve and a self-operating differential pressure regulating valve.

Vacuum class

Vacuum category includes vacuum ball valve, vacuum baffle valve, vacuum inflation valve, pneumatic vacuum valve and so on. Its function is to change the direction of the air flow, adjust the amount of air flow, and cut off or connect the pipe in the vacuum system. It is called a vacuum valve.

Special purpose

Special applications include pigging valves, vent valves, blowdown valves, exhaust valves, filters, etc.

The exhaust valve is an indispensable auxiliary component in the pipeline system and is widely used in boilers, air conditioners, oil and gas, and water supply and drainage pipes. They are often installed at command points or elbows to eliminate excess gas in the pipeline, improve the efficiency of pipeline use and reduce energy consumption.

What is the difference between ball valve and butterfly valve?

1.Refer to different

Ball valve: a valve that is driven by a valve stem and rotates around the axis of the ball valve.

Butterfly valve: also known as flap valve, is a simple structured regulating valve, which can be used for the switch control of low-pressure pipeline media. The closing member (valve or disc) is a disk that rotates around the valve shaft to achieve A valve that is closed.

2. Different characteristics

Ball valve: The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length. Simple structure, small size and light weight. It is tight and reliable, and the sealing surface material of the ball valve is widely used in plastic, which has good sealing performance, and has been widely used in vacuum systems. Easy operation, fast opening and closing, only need to rotate 90 ° from fully open to fully closed, which is convenient for long-distance control.

Butterfly valve: butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, fast switching, 90 ° reciprocating rotation, and low driving torque. It is used to cut off, connect, and adjust the medium in the pipeline. Has good fluid control characteristics and closed sealing performance.

3. Different uses

Ball valve: It can be used for the regulation and control of fluids. Among hard-sealed V-type ball valves, there is a strong shear force between the V-shaped ball core and the metal valve seat of the hardfacing. Material and other media. The multi-way ball valve can not only flexibly control the confluence, divergence, and flow direction of the medium on the pipeline, but also can close any channel and connect the other two channels.

Butterfly valve: The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals and radioactive media. It mainly plays a role of cutting off and throttling on the pipeline. The butterfly valve opening and closing member is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting.
