- Material: Made from cast steel, which provides high strength, durability, and resistance to high temperatures and pressures. Common grades include ASTM A216 WCB, WCC, LCB, and LCC.
- Design: Available in various designs such as floating ball, trunnion-mounted, and fully welded. The trunnion-mounted design is often used for high-pressure applications.
- Sealing: Utilizes soft seats (e.g., PTFE, Teflon) or metal-to-metal seats for sealing, depending on the application and media.
- Operation: Can be operated manually (via a hand lever or gear) or automatically (using actuators like electric, pneumatic, or hydraulic).
