3650-7200 PEC Eccentric Valves

Description

The 3650–7200 PEC Eccentric 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 maintaining the
valve plug position with flow in the pipeline.
The following table shows sizes and port as a percentage of pipe area.

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.

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.
