❓ Frequently Asked Questions
Q What is a 2PC stainless steel ball valve?
A 2PC (two-piece) stainless steel ball valve is a type of quarter-turn valve with a body made of two separate pieces bolted together. This design allows for easy disassembly and maintenance without removing the entire valve from the pipeline. It uses a stainless steel ball to control the flow of media such as water, gas, oil, or chemicals.
Q What materials are available for the 2PC ball valve?
The 2PC ball valve is available in multiple material options including ASTM A351 CF8M (equivalent to SS316), CF8 (equivalent to SS304), CF3M, SS316, SS304, and ASTM A216-WCB for carbon steel versions. These materials ensure compatibility with a wide range of working media and environments.
Q What sizes and pressure ratings are available?
The 2PC stainless steel ball valve is available in sizes ranging from 1/4″ up to 4″, including 3/8″, 1/2″, 3/4″, 1″, 1 1/4″, 1 1/2″, 2″, 2 1/2″, and 3″. The maximum working pressure is 1000 WOG, making it suitable for a wide range of industrial and commercial applications.
Q What temperature range can the 2PC ball valve handle?
The working temperature range depends on the seat material. With RPTFE seats, the valve operates from -20°C to 180°C. With PPL (reinforced polyphenylene) seats, it can handle temperatures from -20°C to 300°C, making it suitable for both standard and high-temperature applications such as steam systems.
Q What certifications does TGV's 2PC ball valve comply with?
TGV's 2PC stainless steel ball valves are manufactured in compliance with ISO 9001:2015 quality management standards (certified by Lloyd's Register) and carry CE/PED certification for the European market. The valves are also tested in accordance with API 598, ensuring reliable leak testing and performance verification before delivery.
Q What are the typical applications for the 2PC stainless steel ball valve?
The 2PC stainless steel ball valve is widely used across many industries including municipal water supply systems, oil and gas pipelines, chemical and petrochemical processing, food and beverage production, HVAC systems, and marine applications. Its corrosion resistance, full bore design, and leak-free performance make it an ideal choice for both on/off control and flow regulation in demanding environments.
