OPERATION AND MAINTENANCE
MODEL 816-1 AND 816-3 AIR OPERATED VALVES
The Model 816 valve is an o
p
en or shut valve for air or

to 6000 PSI. In the normal

when a

a variety of ways to mount the valve.
The 816-3 valve is similar to the 816-1 valve except the

of lower control

an inex

place of expensive high pressure solenoids.

INSTALLATION
Use pipe thread sealant Teflon tape on inlet and outlet
threads. Do not over torque.
Moderate tor
q
ue a
pp
lied with a 6 or 8 inch wrench is
ample. Use ample Teflon tape - 3 or 4 turns not 1 or 2
turns on
p
i
p
e threads. The inlet is the male thread
and outlet is the female thread at the side of the
valve. The one inch thread at the bottom of the valve
can be used to mount the valve throu
g
h a one inch

as or li
q
uid at an

p
ressure between
the minimum and maximum
g
iven above under
s
p
ecifications. Pressure must be relieved for the
valve to shut. If an electric solenoid is used, use the
three wa
y
t
yp
e to relieve control
p
ressure. The
re
g
ulator is NOT shi
pp
ed ox
yg
en clean and should
NOT be used for ox
yg
en service as
p
rovided.
Consult the factory for details on oxygen service.
MAINTENANCE & REPAIR
CAUTION As with any regulator or valve,
particulates or moisture can plug or freeze the
internal filter or valve seat. This can occur when up-
stream dryers are not changed or remain unused for
long periods allowing corrosion materials to
accumulate. In critical applications where it is
important not to lose flow, a larger particulate filter
should be used upstream. Also an orifice such as
the Aqua model 796 should be used downstream.
This reduces the tendency to freeze when moisture
is present. Consult factory for details. The user
should establish time intervals for changing the valve
cartridge, filter and upstream dryers based on
experience and service conditions. Back-up
systems should be used in very critical applications
since field maintenance is hard to insure. The
poppet cartridge 832 is a factory assembled item and
should be replaced if required and not disassembled
unless absolutel
