|
-Line pressure driven -Closes upon control failure -Amplifies and relays weak remote command -Hydraulically controlled On/Off |
|
-Unobstructed flow path -Single moving part -High flow capacity |
|
-Requires low opening and actuation pressure -Progressively restrains valve closing -Prevents diaphragm distortion |
|
-Simple in-line inspection -Easy addition of control features |
