Explosion Proof 3-Piece Ball Valves are typically used in applications that involve flammable process fluids and hazardous atmospheres. These high-pressure valves can be found in industries such as automotive, oil and gas and food processing. These three-piece, full-port valves can be repaired or replaced without removing the entire unit from the pipe line, which saves time and money for both technicians and maintenance staff. These valves are available with a variety of different end connections including butt welded, socket weld, threaded and flanged. They can also be fitted with a wide range of handle types and operating devices as well.
The main difference between one-piece, two-piece and three-piece ball valves is their body design. A one-piece ball valve has a single body portion that cannot be repaired, while two-piece ball valves have two body components which are threaded together or bolted to each other. A three-piece ball valve, on the other hand, has a central section that contains the ball, stem, seals and seats, as well as a handle or other operating device.
3-piece valves also have a hygienic design, which makes them easier to clean. They eliminate dead space inside the valve and outside the valve, which reduces the risk of cross-contamination and provides a better environment for cleaning and handling. Additionally, they have a straight path of flow and do not become narrower on the inside like standard port valves.
Regardless of the type of valve you choose, it’s important to understand how to properly maintain your equipment. This includes depressurizing the valve before beginning any maintenance. Then, you can remove the actuator and any accessories that may be attached to the valve body, if necessary. It’s also important to check the valve for any signs of damage or wear and make sure that it’s functioning within its maximum temperature and pressure ratings. Explosion Proof 3-Piece Ball Valves
