Quarter-Turn Ball Valves

Valve bodies are available in three-piece and two-piece designs. The three-piece valve body features a two level sealing system to provide superior tightness during temperature and pressure variations. It also allows the changing of valve seat without body removal from pipeline. The more economical two-piece valve body performs in applications having fewer fluid pressure and temperature fluctuations, and features a blow-out proof stem design. Bodies are stainless steel and available in ¼ in. to 2 in. port sizes.
The system is completed with a choice of a wide range of optional pilot valves for the operation of the pneumatic actuator, a compact position feedback device, or the company's Top Controller for On/Off or continuous control functions.
