The Selection and Application of Butterfly Valves

The butterfly valve is suitable for flow regulation. Because the pressure loss of butterfly valves in the pipeline is relatively large (it is about three times that of gate valves), the influence of the pressure loss on pipe systems should be fully considered when the butterfly valve is to be selected. Also, take into consideration the firmness of the disc bearing the pressure...

What is the Full Bore and the Reduced Bore Ball Valve

The nominal diameter is the general caliber of various pipes and pipe fittings. Pipes and pipe fittings with the same diameter can be connected with each other and have interchangeability. It is not the actual outer diameter or inner diameter of the pipe, though its value is close to or equal to the inner diameter of the pipe. In the process pipeline system, most valves are designed to limit...

Advantages of Bellows Seal Globe Valves

The design of the bellows seal globe valve is better than that of the ordinary globe valve. So, what are the advantages of bellows seal globe valves compared with ordinary ones? 1. The bellows seal globe valve has no leakage and is applied to high-risk medium. 2. The common globe valve is sealed with packing, and a slide will occur between the valve stem and packing so that the valve is...

How to Make a Longer Service Life of a Ball Valve

A longer service life of a ball valve relies on the following factors: 1. Normal working conditions. 2. Maintain the temperature properly proportional to the pressure. 3. When the ball valve is closed, there is still pressurized fluid inside the valve body. Before disassembly, it is necessary to check the upstream and downstream sides of the ball valve to ensure that there is no pressure in...

How to Select Proper Valves According to Flow Characteristics?

The disc and the shape of the valve flow passage make the valve have certain flow characteristics, which must be taken into account when you select valves. 1. Valves for cutting off and starting the flow of media Generally, valves with small flow resistance and straight-through flow passage are selected. Downward closed valves (globe valves and plunger valves) are seldom used because of the tortuous...

Difference between Globe Valves and Throttle Valves

Globe valve, also called stop valve, is one of the most widely used valves. It is popular because of its durability, easy manufacture, convenient maintenance and low friction between sealing surfaces during opening and closing. It is not only suitable for medium and low pressures, but also suitable for high pressures. The working principle of the globe valve is to make the...

What is Plug Valve?

Plug valve is the valve that uses a tapered or cylindrical “plug” to stop or start the flow. The plug in the plug valve has a hollow passage to pass the fluid. When the valve is open, this bored passage is in line with the flow. When the plug is rotated a quarter turn to change from open to closed positions, the solid part of the plug stops the flow. Plug valve is used in place...

Why Triple Offset Butterfly Valve Superior to the Standard One?

Triple eccentric butterfly valves, also called triple offset butterfly valves, are critical in applications where bubble-tight shut off is required. In some applications, bubble-tight shut off cannot be achieved using double eccentric butterfly valves. Some applications don't lend themselves well to traditional butterfly valves, e.g., applications involving harsh chemicals or media containing...
