Stations pneumatically controlled pumping two-circuit type GAKS-D-7 are designed to create and automatically maintain the pressure of liquid media during hydraulic and pneumatic tests of pipeline valves on test benches; to determine the quality indicators of pipeline valves (tightness class) during hydraulic and pneumatic tests. GAKS-D-7 station has a function of proportional pressure control.
To implement this function, the station has a built-in proportional clamping system, which controls the hydraulic drive of the test bench, minimising axial loads on the valve body when clamping it on the bench.
