OPERATION AND MAINTENANCE

MODEL 816-1 AND 816-3 AIR OPERATED VALVES

The Model 816 valve is an open or shut valve for air or

gas lines up to 6000 PSI. In the normal position with

no control pressure applied the valve is shut.

Providing control pressure to the upper control port

opens the valve. One typical application is to open a

cylinder charging line only when a protective door is

shut. A one inch thread section is provided permitting

a variety of ways to mount the valve.

The 816-3 valve is similar to the 816-1 valve except the

-3 valve uses a larger control piston permitting the use

of lower control pressure. The valve, when used with

an inexpensive low pressure solenoid, can be used in

place of expensive high pressure solenoids.

INSTALLATION

Use pipe thread sealant Teflon tape on inlet and outlet

threads. Do not over torque.

Moderate torque applied with a 6 or 8 inch wrench is

ample. Use ample Teflon tape - 3 or 4 turns not 1 or 2

turns on pipe 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 through a one inch

hole in a panel or mounting plate provided by the

user. Actuating pressure for the valve can be any

non-corrosive gas or liquid at any pressure between

the minimum and maximum given above under

specifications. Pressure must be relieved for the

valve to shut. If an electric solenoid is used, use the

three way type to relieve control pressure.

MAINTENANCE & REPAIR

CAUTION

As w ith any regulator or v alve,

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

accumulate.

In critical appl ications where it is

important not to lose flow, a larger particulate filter

should be used upstream. Al so 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 detai ls.

should establish time intervals for changing the valve

cartridge, filter and upstream dryers based on

experience and service

systems should be used in very critical applications

since field maintenance is hard to in sure.

should be replaced if required and not disassembled

unless absolutely necessary. Spare cartridges are

available at a nominal cost and should be kept on

hand if rapid repairs are required.
