Valvesonly is the best Trunnion Ball Valve manufacturer in USA. Trunnion ball valves are used to start and halt media flow in pipes. The ball of a trunnion ball valve is linked to the trunnion on one end and the stem on the other. Because the ball is permanently attached to the trunnion, it maintains a proper seal on all sides and prevents excessive torque from being imparted to the stem. As a result, a trunnion ball valve designed for greater pressure applications may seal better and require less torque to turn. TRUNNION BALL VALVE VS. FLOATING BALL VALVE:m The ball is forced against the downstream seat by the in-line pressure in a floating ball configuration, generating the tightness. The ball must be spun against both the in-line pressure and the friction of the seats as it moves from closed to open. In other words, both in-line pressure and the nature of the valve seats contribute to the torque required to operate the valve. When operating pressure or the valve size increases, or when the nature of the seat is made more robust, the amount of torque required increases drastically. The ball is put into a central bottom shaft in a trunnion layout (the trunnion). The ball is attached to the stem and the trunnion, indicating that it is not floating but rather fixed. The tightness is caused by the lining pressure pressing the seats on the ball. This means that the ball does not have to rotate against both the in-line pressureand the valve seats during operation, but only against the pressure of the valve seats. A trunnion ball valve has the following advantages: • It can be used for high or low pressure applications. • In comparison to the floating ball valve, the trunnion-mounted ball valve is better suited to high-pressure applications and has larger dimensions. • A drain or bleed connection is usually included with a trunnion, making it suitable for use as a dual safe device. • Reduced operating costs.
