Description
Technical Specifications
SPECS Single Seated Balance Control Valve, Compared with top guided single seated Control Valve, Its dynamic stability is better with balance sealing ring and could work smooth under higher pressure drop. Compared with cage guided single seated control valves, it’s better suited for applications involving fluid with entrained particles, and its trim will not be locked.

Design Features
1. Compared with singled seated control valve(unbalanced Plug) it can work in applications with higher pressure
2. With small unbalanced force,large allowing pressure difference,stable operation due to the use of balanced plug
Benefits
1. The structure is relatively simple so it is suitable for occasions with particle impurities, and can reduce stuck
2. Compared with singled seated control valve (unbalanced Plug), the required thrust is smaller in the same closing pressure, so a pneumatic diaphram actuator with smaller thrust can be selected to lower the cost.
