OVERVIEW
The model ACP pressure-balanced cage type control valves are designed for heavy duty service. The valve plug employs a pressure balance function to control high differential pressure fluid with small actuator force.
The ACP realizes seat leakage performance as single seat valve by seal ring structure. In addition, the ACP is equipped the cage plug with a scraper ring to prevent a malfunction caused by foreign object enter between the cage plug and the cage. The actuator is adopted a compact and powerful diaphragm motor.
The ACP is widely applicable for reliable control of high or low temperature, high differential pressure process lines where dynamic stability, dynamic stability, low noise, anti-cavitation/flashing are required.
