GA120 Cage Guided Single Seated Angle Control Valve

This series is cage guided high pressure control valve with pressure balanced plug. It is a high performance valve with large capacity, good dynamic stability and is applicable to critical situation. Only a small operation force can achieve stability control due to the pressure balanced plug structure, and is suitable for high pressure difference situation.

Features

1, The valve body and bonnet are pressed together with stud and the design specification is in accordance with ASME.

2, Solid cage guide and unique balanced sealing ring (GF TFE structure for room temperature, soft graphite 1398 & Graph-lock structure for high temperature ) makes a good stability for the plug movement, vibration and mechanical noise are reduced.

3, It is easy to remove and replace trim even if the valve body is in the pipeline, and this makes the field maintenance much easier and fast. The trims of GA120 can be changed to multi-hole trims of GA210 to be suitable for different situation and ensure the output velocity is in the security range. Cavitation and noise can be reduced effectively.

Benefits

1, Small actuator can be used on the balanced structure plug, but the valve can overcome higher pressure difference compared with non-balanced straight through single seated valve.

2, The flow characteristics can be changed by changing different cages, this increases the parts commonality.

3, The noise can be reduced by around 10dB compared with regular single/double seated control valve.
