Description
The 3– 36” PEF 100% Port Eccentric Plug Valves have welded nickel seats that provide excellent
resistance to corrosion and damage, and prolong the life of the resilient plug facing. The valve rotates
90 degrees from full open to full closed. Clockwise rotation of the valve stem closes the valve.
If an actuator other than a DeZURIK is to be mounted, the actuator must be capable of seating and
unseating the plug and maintaining the valve plug position with flow in the pipeline.
This valve is a pressure vessel. Failure to release pipeline pressure may result in
personal injury and/or flow system damage. Completely release pipeline pressure
before removing the actuator from the valve or removing the valve from the
pipeline.
Handling
Lifting the valve improperly may damage it. Do not fasten lifting devices to the
actuator, plug or through
the seat opening in the body. Lift the valve with
slings, chains or cables fastened around the valve
body, or fastened to bolts or
rods through bolt holes in the flanges.
Required Tools
This valve is assembled using only metric fasteners. To service this valve, you should have a full set of
combination wrenches, Allen wrenches, a large flat tipped screwdriver, a flat pry bar, a pin punch and a
dead blow hammer.
Note:
You may want to machine a shaft to aid you in removing the lower bearing from the body. See
“Disassembly”
section.
Fusion/Powder Coated Valves
Valves with fusion/powder coated exterior paint require flat washers to be installed
under the flange nuts when installing the valve to the pipeline flange to prevent the
paint from cracking or chipping.
