InstallatIon

Exceeding the recommended pressure and tempera-

ture limits indicated on the nameplates of your Jordan

valve control valve, can result in personal injury and

property damage. Jordan Valve recommends the

installation of a relief valve to protect against overpres-

sure situations.

The Mark EW Series valve bodies are designed to

meet speciﬁc conditions for ﬂuid control, temperature,

pressure and pressure drop. The limiting factor on

these valves can be the body/trim material combina-

tions. Do not install these valves in any other applica-

tions without ﬁrst consulting with your Jordan Valve

representative.

During installation, Jordan Valve recommends the use

of a sling to protect the painted surfaces of the valve.

Position the sling to avoid damage to tubing and ac-

cessories.

1. Inspect the valves for shipping damage and

foreign debris while uncrating.

2. Ensure the pipeline is free of welding slag,

chips and other debris by blowing out the line

before installation.

3. Position the valve so the arrow on the valve

body is in the same direction as the pipeline

ﬂow.

4. Speciﬁc orientation of the control valve as-

sembly is ﬂexible, unless limited by the

seismic criteria. Normal positioning

is with the actuator vertical above the valve

body. Should a different position be required,

be aware that the result may be uneven valve

plug and cage wear, and inefﬁcient opera-

tion of the control valve system. Also,

be aware that the actuator may need addi-

tional support. Consult Jordan Valve for further

information on orientation.

5. Always employ proper piping and welding

practices when installing the valve in the line.

If welding is required, internal elastomeric

parts may remain in place. If the valve

has buttwelding ends and composition

trim, remove the composition trim prior

to welding into the line.

6. For ﬂanged bodies, install an appropriate gas

ket between the pipeline and valve body ﬂang

es.

7. With leak-off bonnet construction, remove the

pipe plugs (Figure 1, Keys 14 and 23)

to connect the leak-off piping. To avoid an

interruption of service during inspection or

maintenance, install a three-valve bypass

around the control valve assembly.

8. Most Jordan valves are shipped with

the actuator already installed according to

customer speciﬁcations. If your actuator has

been shipped separately, refer to the appropri-

ate mounting instructions in the actuator

manual.
