This is because the external pilot line acts on a surface area three times (3 in. 2) that which the internal pilot pressure acts on. Actually, 1,500 lb of force is already being exerted by the load on the spring. Therefore, the external pilot pressure only has to develop 300 lb of additional force to open the valve.
