Terofox Quarter-Turn Ball Valves


Ball valves are mostly used in shutoff applications. They are not recommended to be used in a partially open position for a long time under conditions of a high pressure drop across the valve, thus the soft seat could tend to flow through the orifice and block the valve movement. With the type of body, ball valves can be more or less easily maintained. Drop pressure relative to its hole size is low.The seat material resistance of the ball valve limits the working temperature and pressure of the valve. The seat is plastic ( such as PTFE, RPTFE, 50%Carbon powder + 50% PTFE ) or metal ( S.S. + Stellite / Chrome hard face ) made.

They are used in diversity of applications such as steam, water, oil, gas, air, corrosive fluids, and can also handle slurries and dusty dry fluids. Abrasive and fibrous materials can damage the seats and the ball surface. Hence, purchasers must provide the necessary information on fluids / temperature for consideration of seat material. For valves interior structures, Terofox provides blow-out-proof stem (Fig. 01) and anti-static device (Fig. 02) as essential parts in the valve. API607 Fire Safe Design (Fig. 03) is optional for some certain applications.
