There are five general body styles of ball Valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve-especially the casing that contains the ball itself-are manufactured and assembled. The valve operation is the same in each case.

Application Fields of Shell Filter Material in Wastewater Treatment
After reading the previous information and product descriptions, you probably have a good understanding of what shell filter material is and its main uses and features. In this article, we will go into more detail about the application fields of nutshell filter materials in wastewater treatment systems.
Shell filter materials are widely used in various wastewater treatment systems. They are commonly applied in the treatment of domestic and industrial water to remove suspended solids and impurities, thereby improving the quality of the effluent. In industrial wastewater treatment, these materials are especially effective in removing oil and particulate matter from the water. Similarly, they are used in oil field sewage treatment, where the primary goal is also to eliminate oil and suspended solids, ensuring that the treated water meets required standards.
The nut shell filter material is known for its high hardness, wear resistance, and pressure resistance. It can withstand up to 23.4 kgf and has excellent chemical stability, meaning it doesn’t dissolve in acids or bases. Its strong adsorption and interception capabilities allow it to capture particles efficiently, with an adsorption rate ranging from 27% to 50%. The material is hydrophilic, resistant to oil immersion, and has a specific gravity of 1.25 g/cm³, slightly higher than water. Its filling density is 0.85 g/cm³, making it easy to backwash and regenerate. Compared to other filter media, it offers cost-effective operation, low backwashing intensity (6.71 L/s·m²), and a fast filtration speed (24–26 m/h). In oil field applications, it can achieve an oil removal efficiency of up to 95%, reducing oil content to below 5 mg/L.
Zhengda Nut Shell Filter Material is produced by a company that emphasizes a professional, practical, efficient, and innovative spirit. With a solid internal management system, the company ensures high-quality products and reliable performance in wastewater treatment applications.
In addition, there are different styles related to the bore of the ball mechanism itself.
Ball valves in sizes up to 2 inch generally come in single piece, two or three piece designs. One piece ball valves are almost always reduced bore, are relatively inexpensive and generally are throw-away. Two piece ball valves are generally slightly reduced (or standard) bore, they can be either throw-away or repairable. The 3 piece design allows for the center part of the valve containing the ball, stem & seats to be easily removed from the pipeline. This facilitates efficient cleaning of deposited sediments, replacement of seats and gland packings, polishing out of small scratches on the ball, all this without removing the pipes from the valve body. The design concept of a three piece valve is for it to be repairable.
