AQF-Type Accumulator Safety Ball Valve
The AQF-type safety ball valve is designed to safely control the connection between the accumulator and the hydraulic system and to isolate the accumulator from the circuit when necessary. Thanks to its ball valve structure, it enables fast opening and closing, offers high pressure resistance, and minimizes flow loss.
This valve provides a leak-proof and reliable solution for safely shutting off the accumulator before maintenance, checking its pressure, or disconnecting it from the system. With its compact design and compatibility with gauge and relief port connections, it is widely used in industrial hydraulic circuits.
