Warning: Jordan Valve Control Valves must only be used, installed and repaired in accordance with these Installa-
tion & Maintenance Instructions. Observe all applicable public and company codes and regulations. In the event
of leakage or other malfunction, call a qualified service person; continued operation may cause system failure or
a general hazard. Before servicing any valve, disconnect, shut off, or bypass all pressurized fluid. Before disassem-
bling a valve, be sure to release all spring tension.

The Mark 4150 and 4160 Series pressure controllers
are designed to provide years of reliable and accurate
service.
These instructions cover maintenance, adjustment,
and changes in mode of control.
These instructions are intended for the controllers
in general. Any instructions that apply to specific
controllers will be indicated by model number in the
instruction.
Model numbers are stamped on the nameplate locat-
ed inside the cover of the controller (Key 29, Figure 4).
Controllers
Inspect the controllers for shipping damage and for-
eign debris when uncrating.
Valve
Ensure the pipeline is free of welding slag, chips and
other debris by blowing out the line prior to installation.
It is recommended that a strainer be installed up
stream of the valve to protect the valve from foreign
debris in the line. Jordan Valve recommends a stan-
dard three-valve maintenance bypass be installed.
This allows isolation of the control valve without shut-
ting down the pipeline system.
The valve should be positioned on the line so the flow
direction indicator corresponds to the direction of the
flow of the pipeline.

Installation & Maintenance Instructions for the
Mark 4150 and 4160 Series Pressure Controllers
If the body is flanged, the bolts should be tightened up
evenly to reduce risk of damage to the valve body and
the flange.
A good quality thread lubricating compound should be
used on all male connections if the body has screwed
connections.
Control Line Connectors
The connections should be made in an area of the
pipeline that is free of bends and elbows. Piping
connections should be made with 1/4" or 3/8" pipe or
tubing.
Tap the pipeline as close to the valve body as possible
allowing for these limiting factors.
1. The tap area should be an area that is free
from abnormal velocities.
2. The ideal distance away from the body should
be 10 x the pipeline diameter.
The control pressure line is run from the tapped hole in
the side or the back of the case to the main pipeline.
Install a lock shield needle valve in the control line to
slow down the controlled pressure or to dampen out
any pulsations. While the control valve is operational,
the needle valve must never be entirely closed.
An air vent is provided on all controllers and works well
when air is used as the operating medium. When gas
is used the vent can be removed, this allows for an ad-
ditional 1/4" NPT connection for gas to be piped away.
