Due to our agreement with this statement, we err on the side of caution and do not publish
installation torque values for NPT threads. SAE J1926 fittings, on the other hand, are supplied
by various manufacturers who publish installation torques in catalogues. Please follow those
installation instructions for use in our 316 stainless steel valve bodies.
It is not recommended to use liquid sealant on the NPT connections. Often, the sealant fluid
leaks into the valve is gets deposited on critical areas such as the seat, the pilot orifice, and
other areas that inhibit optimal performance and quality sealing.
Make sure that connecting pipes or tubes are clean and free of particulates. Particulates and
debris are the most common reason for valves not sealing properly.
Install a filter upstream and close to the solenoid valve (see details in Filter section).
No lubrication is required. Most often, it is not necessary to lubrication internal components.
Occasionally, a very small amount of grease may be used to simply wet the piston and bonnet
tube o-rings for ease of assembly or low friction movement. However, the valve should function
well without it.
If the valve has been disassembled for service or cleaning, re-install the bonnet retainer with 23
ft*lbs of torque using a spanner wrench purchased from Clark Cooper.
Filters:
Foreign matter such as particulates, rust flakes, PTFE tape, pipe dope, etc., can jam moving parts
within a solenoid valve, clog the small orifices, or damage softer sealing surfaces. The result can
be a failure to open, close, and seal. A strainer or filter with 200 mesh (0.0029" gaps) or finer is
recommended for the EH40 Series products.
The strainer should be placed upstream (inlet side) and as close to the valve as possible. Be sure
to select a model that is safe for the inlet pressure. Size the filter so that the pressure drop
across it is acceptable for the flow rate.
