We have to change the seat and cage in a large (8" EHT) valve for new spare parts and the weight of the valve and bonnet is 2200kg alone plus the actuator.
Question 1 - What is the normal procedure to lift the valve as I presume the lifting lugs on the actuator top is purely to lift the actuator only. If so what is the normal practice to lift the bonnet and valve as no obvious lifting points and the manual does not state.
I believe the actuator material is too thin to handle the lift of the bonnet and valve also
Any advice is welcome..
