Our engineer dismantled the valve and cleaned all parts. Upon inspection he found the electrical actuator (157B4033) only worked in one direction and the mechanical actuator (157B3171) was cracked.
The valve was repaired using the following new parts:-
157B8001 Assembly kit
157B3171 Mechanical actuator
157B4997 PVE seal kit
157B4033 Electrical actuator
The repaired PVG32 valve was tested and returned to our customer.
