Disassembling the Separator and Main Valve Section
Turn the product upside down for easy dismantling of the separator and main valve.

spring, the main valve and screen. Loosen the valve seat with a box wrench and
remove it from the body.
Check for damage on the seating and sliding surfaces of the main valve, the

At start-up following shutdown for a long period, always blow down the piston
section of the body through the plug (option).
