Automation Solution:
For quarter-turn valves (ball & butterfly valves), there are pneumatic, electric, electro-hydraulic, gas hydraulic, and gas over oil actuators for both on-off and modulating duties available. Typical automation solutions are such as:
-Shut Down Valves
-Emergency Shut Down Valves (ESDV): Quick closing type
-Motor Operated Valves (MOV)
-Hydraulically Operated Valves
-Gas Over Oil Operated Valves: Line gas is used as the actuating medium, Emergency manual operation by means of hand pump
