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.
