3- -- 36" PEF 100% Port Eccentric Plug Valves
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 thr ough
the seat opening in the body. Lift the valve with
body, or fastened to bolts or
rods through bolt holes in the flanges.
slings, chains or cables fastened around the valve
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

Actuator Stop Adjustments
Closed Position
Because of the eccentric action of this valve, the closed position of the valve is dependent upon the
pressure drop expected when the valve is closed. To adjust the valve closed position, follow these
steps:
This valve is a pressure vessel. The bonnet will blow off the valve if the bonnet
bolts are removed with pressure in the valve and pipeline media can be haz ardous.
Completely release pressure before disassembling the valve.
1. Relieve pipeline pressure.
Moving parts from accidental operation of power actuator can cause personal
injury or equipment damage.
Disconnect and lock out power to actuator before servicing.
2. If the actuator is powered, disconnect and lock out the pneumatic, hydraulic, or electrical power
to prevent accidental operation of the actuator.
3. Back off the actuator closed position stop as described in the Actuator Instructions.
4. Close the valve with the torque specified in the Actuator Instructions.
Note: This torque is the amount required to seat the plug for a given pressure drop across the valve. To
avoid excessive plug and seat wear caused by over torquing, use the actual pressure drop across the
valve when determining correct closing torque.
5. After the valve has been closed using the correct amount of torque, set the actuator closed
position stop to limit actuator travel at this position.
Lubrication
This valve does not require routine maintenance lubrication, except for special application. If the valve
is disassembled, lubricate the packing and the plug journals as follows:
Packing
Packing lubrication requirements are dependent upon the packing material.
• PTFE PACKING: Requires no lubrication.
• A

Field Test
Stroke the valve between the fully open and fully closed positions to verify that the valve and actuator
are functioning properly. Prior to any field pressure test above the valve design pressure, contact
DeZURIK.
Test pressures above valve design pressure can cause leakage, permanent
or structural failure to the valve and personal injury.
Valve Exercising
Each valve should be operated through a full cycle and returned to its normal operating position on a
time schedule that is designed to prevent a buildup of media deposits that could render the valve
inoperable or prevent a tight shutoff.
The interval of time between exercising valves in critical applications or valves subjected to severe
operating conditions, should be shorter than valves in less critical installations. The time period for
valve exercising should be based on local experience.
Emergency Operation
Operate the valve as under normal conditions, taking care to bring the plug to the position required by
the particular emergency condition
