The three-piece ball valve has a single main valve body and two separate piping connectors. The pipe connectors are attached to the pipelines either by threading or welding. A three-piece design allows the piping connections to be maintained without interruption by extracting the valve body and moldings.

The ball, seat, or stem can be replaced quickly after installing a three-piece ball valve. It is also more expensive than a two-piece ball valve due to its complex design. Notwithstanding that fact, the valve can still perform for the desired period with minimal maintenance costs incurred in the long term.

Materials:

Three-piece ball valves are provided in a diverse array of construction materials, each with its distinctive characteristics. In the construction of 3-piece ball valves, the following materials are frequently employed:

• Brass:

Brass is a popular option for 3-piece ball valves due to its durability and strength. Additionally, it is a viable alternative for low-pressure applications due to its affordability.

• PVC:

PVC is a lightweight and corrosion-resistant plastic frequently employed in 3-piece ball valves installed in water and wastewater treatment applications. Additionally, it is a viable alternative for low-pressure applications due to its affordability.

• Stainless Steel:

Stainless steel is a favored material for 3-piece ball valves due to its durability and resistance to corrosion. It is also accessible in various grades, enabling it to be employed in various applications.

• Bronze:

This corrosion-resistant alloy is frequently employed in 3-piece ball valves subjected to the harshest environments. It is also a viable option for high-pressure applications due to its durability and strength.

Manufacturing Process of Three-Piece Ball Valve

1. High-grade brass, stainless steel, or other compatible materials shall be selected depending on the application’s requirements.
2. It is forging or casting the valve component into the desired shape and strength. It involves forging, which provides better mechanical properties, and casting, which is done for intricate shapes.
3. Precision machining processes, such as CNC milling and turning, give each valve component the required dimensions and tolerances.
4. Surface treatment is done on all components to purify impurities and prepare them for welding. This usually happens through sandblasting or Chemically.
5. The ball, stem, seats, and other internal components are assembled into the valve body. With the three-piece design, maintenance, and assembly is easy.
6. The three portions of the valve body are TIG or MIG welded. This provides a mechanical bond with absolute tightness.
7. In some cases, a thermal treatment could be introduced after welding to reduce stresses and improve the material properties.
8. There are surface treatments like electroplating or coating for this valve that give better resistance against corrosion and durability.
9. Leak testing of every assembled valve, including hydrostatic and pneumatic tests, is conducted to ensure proper working and free from ruptures.
10. Dimensional verification of the valve is observed against all requirements of industry standards and specifications regarding dimensions, surface texture, and quality in general.
11. The valves are identified by size, pressure rating, the material used for construction, and the manufacturer.
12. The finished valves are carefully packed to protect against any damages during transport and storage so they can be presented to the customer in the best condition.

Lifespan of Three Piece Ball Valve

The welded-type three-piece ball valve works typically from 8 to 10 years based on operating circumstances, maintenance habits, and material conditions in service. Some maintenance practices and proper handling would lengthen the life span of the valve.

Surface Treatment of Welded Type Three-Piece Ball Valves

In this stage, the surface of the valve is cleaned to remove impurities, oils, or residues that might affect the adhesion of the ensuing coats. Base cleaning is necessary for the cleanliness of the base so that the successive surface treatments applied to the valve yield maximum effectiveness.

The valve is further sent for specialized surface preparation techniques like sandblasting or shot peening. The surface is further treated afterward by different advanced coatings against corrosion, either through electroplating using materials like nickel or chromium or some durable polymer coating.

Moreover, this will improve the friction and abrasion resistance of the treated surface of the welded type three-piece ball valve to some degree during operation and prevent damage. This includes an intensive inspection and quality checking, the last procedures in the coating process to ensure that the layer is applied uniformly and defect-free.

Advantages

• In the long term, a three-piece ball is more cost-effective due to its easy cleaning and maintenance.
• Removing the valve’s primary body can prevent a line shutoff without affecting the connections.
• The valve offers full port and bidirectional shutoff capabilities.
• The valve gaskets can be effortlessly replaced by unscrewing the covers.
• Compared to a one or two-piece ball valve, the connection in a three-piece ball valve is complete.
• These valves are capable of operating in a high-pressure vacuum.
