Description
The 1000WOG 3PC Female Thread Ball Valve and the gate valve belong to the same type of valve. The difference is that its closing member is a sphere. The sphere rotates around the center line of the valve body to open and close. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of media. The three-piece ball valve is a new type of valve that has been widely used in recent years.

Differences And Comparisons Between One-piece Ball Valves, Two-piece Ball Valves And Three-piece Ball Valves
One-piece ball valve refers to a ball valve that is connected by a small-diameter internal thread and consists of an integral one-piece valve body. The integral valve body is often used in small-sized valves.
Two-piece ball valve, also called two-piece ball valve, refers to a commonly used valve with small diameter internal thread connection, the valve body is divided into two parts, and the buckle form is used. Three-piece ball valves are connected with internal threads. The valve body consists of three parts. They are usually used for larger and more important valves.
1. Distinguish from the structure
The one-piece ball valve is an integrated ball valve, which is composed of a ball, a PTFE ring, and a locking nut. The diameter of the ball is slightly smaller than the diameter of the pipe. It is similar to the Cantonese ball valve. It is generally reduced in diameter, and the actual circulation hole diameter is one specification less than the diameter. , the traffic is relatively small. The two-piece ball valve is composed of two parts. The sealing effect is better than that of the one-piece ball valve. The diameter of the ball is the same as that of the pipe. It is easier to disassemble than the one-piece ball valve. The three-piece ball valve is composed of three parts, the valve cover on both sides and the middle valve body. The three-piece ball valve is different from the two-piece ball valve and the one-piece ball valve in that it is easy to disassemble and repair. Stronger pressure resistance.
2. Distinguish from pressure
The pressure resistance of three-piece ball valves is much higher than that of one-piece and two-piece ball valves. The main three-piece ball valve is fixed by four bolts on the outside, which plays a good tightening role. The precision cast valve body can reach a pressure of 1000psi≈6.9MPa. Higher pressures require a forged valve body.
3. Distinguish from an economic perspective
Since the main body material of the one-piece ball valve is less than that of the other two types, the price is favorable and it has the same use as the Cantonese ball valve. The price of the two-piece ball valve is higher than that of the one-piece type. The three-piece type has a higher pressure valve body composed of three parts, and the material is higher than the other two types. The price is higher than that of the two-piece and one-piece ball valves.
The Use Of Two-piece And Three-piece Ball Valve
When properly maintained, three-piece ball valves are the most durable option among these product variations. Three-piece ball valves are ideal for high-cycle, high-pressure applications that experience extensive wear and tear. Most notably, three-piece ball valves have the ability to disassemble components for cleaning or repair, sometimes with the valve body still in place. This means that wear-prone elastomeric components, such as seals, can be replaced or replaced based on changing system conditions or age. Three-piece ball valves are available in a variety of connection methods, including female National Pipe Taper (FNPT), socket weld, and pipe socket weld. Mounting bolts that can be screwed directly into the mounting flange Reduces the possibility of the assembly nut being dropped or lost when installing or servicing the valve Two-piece pipe adapter that allows the flange to rotate independently of the pipe connector for easier alignment Quickly and accurately align the valve center section Self-wear compensating stem seal design ensures long-term leak-free service
