3.0 Description and Intended Use
The Betts 1” Water Drain Valve meets HM183 requirements for an
internal self-closing stop valve and is ideal for use as a water
drain/sampling valve. The valve is manually operated with use of a pull
cable and offers a 1” NPT male threaded inlet and ¾” NPT female
threaded outlet. Optional features include a conversion to pneumatic
actuation or a 1” NPT female outlet.
The shear section is located above both the pull lever and push stem
connection point which helps to provide a cleaner separation in the
event of an under-carriage impact. The valve meets the shear section
requirements of 49CFR §178.345-8 and is tested per TTMA RP84.
The valve body and O-ring holder stem are constructed of lightweight
anodized aluminum to maximize durability and corrosion resistance.
The valve push stem is 316 stainless steel and is supported by an oil
impregnated bushing with FKM-B (Viton® B) standard seals for
compatibility with a wide range of products and temperatures. The
simplistic design allows for easy tear-down and maintenance.
Valve MAWP: 25 psi [1.7bar]
Minimum Bursting Pressure: 100 psi [6.9bar]
Valve Temperature Range: –45F to +380F [-43C to +193C]
FKM-B (Viton® B) - Seals
Weight: .82 lbs [.38kg]
*Dimension will vary dependent on thread engagement.
4.0 Installation
4.1 Prior to installation, it is recommended to verify proper function of the water drain valve.
Refer to 5.0 for detailed instructions.
4.2 Apply PTFE tape or thread sealant to the male threads of the water drain valve. Ensure
that the sealant is compatible with the product being hauled or stored.
4.3 Thread the valve into the 1” NPT fitting or sump.
4.3.1 The flow rates of the valve will vary depending on the type of fitting used. The
major diameter of the valve is 1.20” in diameter. Any full or half coupling used
must have an inside diameter of a minimum of 1.25”. It is not recommended to
use a full coupling as the flow path of fluid through the valve windows will be
drastically restricted.
4.4 Use an adjustable wrench or 1-5/8” wrench on the valve hex to fully tighten the valve to
the sump or fitting. Overtightening the valve can cause damage to the threads.
4.4.1 Check the threaded mounting joint for leakage. Additional tightening or additional
PTFE tape or thread sealant may be required to ensure a leak tight joint.

4.5 Apply PTFE tape or thread sealant to the male fitting/connection that will install to the
female outlet threads of the water drain valve. Ensure that the sealant is compatible with
the product being hauled or stored.
4.6 Use a wrench and fully tighten the outlet piping to the valve
4.6.1 Overtightening the fitting/piping can cause damage to the threads.
4.6.2 Additional tightening or additional PTFE tape or thread sealant may be required to
ensure a leak tight joint.
4.7 Ensure outlet piping is supported to reduce the transmission of vibration or load which
may damage the valve.
4.8 Use the lever mounting 7/16” hole to attach cable.
4.8.1 It is important to review the cable system to ensure the valve spring force is
sufficient to close the valve and retract the cable. Reduce cable friction by
minimizing bends and long runs.
4.8.2 Use of a wire thimble will help prevent the cable from being damaged during
actuation
4.8.3 A fusible link is available as an option if additional thermal protection is desired.
The fusible element melts at not more than 250°F and uses a nonslip adjustable
cable attachment. The Fusible Link part number is 76173SLZC.

5.0 Inspection and Testing
5.1 Bench Test:
•Use Betts Part number: 76248SLBN Inlet Test Fixture 1-11.5NPS
•Use Betts Part number: 76249SSBN Outlet Test Fixture ¾-14NPS
•Use Betts Part number: 76250SSBN Outlet Test Fixture 1-11.5NPS
5.1.2 Use silicone grease to lubricate the O-ring in the test fixture
5.1.3 Thread the fixture all the way down onto the valve
5.1.4 Attach a regulated air supply to the test fixture and set at the desired test pressure
(valve MAWP is 25 psi).
5.1.5 Dunk the valve into a water tank and check for bubbles propagating from the outlet
of the valve indicating a leak of the main seal.
•If the valve leaks, disassemble the test fixture and check the valve O-ring and
valve seat for any debris, dirt or scratches. Repair the valve and retest.
•If leaks are propagatingfrom the threads of the valve, inspect andclean/change
the O-ring seal (-217) in the fixture.
5.1.6 Thread the plug fixture with gasket into the outlet of the valve body sealing on the
face of the valve. Ensure that the face of the valve body is free of any dirt debris
or scratches.
5.1.7 With the regulated air supply still attached, dunk the valve into the water tank and
open the valve. Check for bubbles propagating from either the valve body or the
push stem seal.
•If the push stem leaks, repair the valve and retest.

the side plate isn’t damaged when
removed.
6.19 Install the Boot (12) onto the valve.
•To aid assembly, turn the top portion of the boot inside out and push completely
onto the valve body boss. Once installed roll top portion of boot into place.
6.20 Slide the Push Stem (6) and Lever (7) into the valve.
•Ensure that the Push Stem (6) does not damage the Push Stem O-ring (15) by
wiggling the push stem slightly during insertion.
6.21 With the Push Stem (6) and Lever (7) in place, install the Nylon Washers (10) on both
sides of the Lever (7) with the Binding Barrel (8)
6.22 Apply removable thread lock on the Button Cap Screw (9).
6.23 Screw the Button Cap Screw into the Binding Barrel (8) using a Phillips head screwdriver
and a 1/8” hex key (Allen) wrench in the Binding Barrel. Tighten down until the is minimal
slop between the NylonWashers (10) and the Lever (7). Overtightening will cause too much
friction and the valve will not operate properly. Manually actuate the valve to ensure the
spring closes the valve.
