3.0 Description and Intended Use
The Betts’ Emergency/Remote Shutdown Air Valve is a two position push/pull control valve. When plumbed and
mounted correctly, it fulfills the requirements of a remotely actuated means of closure per US DOT 49CFR§178.345-
11(b)(1)(i) and CSA B620-20 clause 5.6.12.3(b), (c), and (f). The Emergency/Remote Shutdown is mounted on the
end of the cargo tank farthest away from the loading/unloading outlet with normal position of the valve in the pulled-
out position and initiates shutdown function when the knob is pushed in. Please note, the Emergency/Remote
Shutdown Valve does not provide provision for thermal activation. If required, fusible plugs should be installed in-
line as needed.
The valve block is lightweight anodized aluminum. The valve includes a detent retention feature for positive click-
in feel during operation. All ports are ¼” NPT. The valve can be mounted via the through holes in the valve body
or through a Ø.81” hole in a panel and secured with the ¾“ hex nut (included).
Simplified plumbing schematics are provided below for the two most common methods of operation. A detailed
plumbing schematic is available upon request. Verify proper shutdown function once valve is installed and test
monthly during active service.
Plumbing Option 1
Emergency Shutdown provides positive air signal
Plumbing Option 2
Emergency Shutdown exhausts air system pressure
Knob pushed-in position: Positive
air signal is sent from port 2 to
compatible Air Panel or Master
Control Valve which shuts down
pneumatic valve system.
Knob pushed-in position: Port
2 exhausts air pressure from
air-lines and shuts down
pneumatic valve system.
Knob pulled-out position: Port 2
exhausts air pressure from Air
Panel or Master Control’s reset
ports and the cargo tank valve
system is now operational.
Knob pulled-out position: Port
2 supplies air pressure to
pneumatic valve system and
the cargo tank valve system is
now operational
4.0 Installation
4.1 Per US DOT 49CFR§178.345-11(b)(1)(i), the Emergency Shutdown Valve must be “located more
than 10 feet from the loading/unloading outlet where vehicle length allows, or on the end of the
cargo tank furthest away from the loading/unloading outlet.”
4.2 Per §172.328(d) “each on-vehicle manually-activated remote shutoff device for closure of the
internal self-closing stop valve must be identified by marking “Emergency Shutoff” in letters at least
0.75 inches in height, in a color that contrasts with its background, and located in an area
immediately adjacent to the means of closure.”
4.3 The valve can be mounted via the through holes in the valve body or through a Ø.81” hole in a
panel and secured with the ¾“ hex nut (included). See figures 1 and 2.
4.4 The valve should be mounted with exhaust port facing down protected from moisture. If needed,
utilize an elbow and drop tube to route the exhaust to an area free of moisture or debris.
4.5 If airline conditioner/antifreeze is used, it must be compatible with O-ring material.

5.0 Inspection and Testing
5.1 Bench Test
5.1.1 Inspect all components for corrosion or damage and replace if necessary.
5.1.2 Actuate the valve twice to ensure it is functioning properly with smooth operation.
Ensure that the detent bushing feature is functioning properly with click-in feel in both
open and closed positions.
5.1.3 Check and ensure the end cap is snapped into the back of the valve and ensure that
the vent hole in the cap is not plugged or blocked.
5.1.4 Apply line pressure of 90-125 psi to the ports shown in the table below and inspect for
leaks. See Disassembly and Rebuild section for needed repairs.

5.2 Field Testing (monthly testing)
5.2.1 Visual inspection:
5.2.1.1 Inspect exterior of valve for corrosion or damage. Pay special
attention to the area where the stem moves in and out of the bushing.
5.2.1.2 Inspect for any air leaking at any of the fittings, at the stem or end cap.
5.2.1.3 Look for leakage of fluid out of exhaust port. This could be an
indication of a seal failure in one of the Emergency Valves or Air
Manifold. Investigate and repair the problematic component.
5.2.1.4 Ensure the end cap is snapped into the back of the valve and ensure
that the vent hole in the end cap is not plugged or blocked.
5.2.1.5 Inspect exhaust port and make sure it is unobstructed and oriented in
an area that is protected from weather, debris or moisture.

Valve make sure the cargo tank is safe to simulate a shut down.
Cargo tank and piping should be empty and all end of piping stop
valves and caps should be closed and in place.
5.2.3.2 With Emergency Valves or Air Manifold Valves open, actuate the
Emergency/Remote Shutdown Valve.
5.2.3.3 To satisfy 49CFR§178.345-11(b)(1), inspect Emergency Valves and

seconds of actuating the Emergency/Remote Shutdown Valve.
5.2.4 Repair or replace the Emergency/Remote Shutdown Valve if it does not meet any
of the monthly field testing requirements.

6.1 Disassembly
6.1.1 Use the two ½” open ended wrenches to remove the Control Knob (8) and the
Flange Nut (7) from the piston (2). If the flange nut (7) is spinning with the piston, use
a small screwdriver to pop off the end cap (10). Insert a 7/32”Allen wrench into the
end of the piston to prevent it from spinning to remove the Flange Nut (7).
6.1.2 Push the piston (2) through the back of the valve. If the end cap (10) is still on, apply
enough force to pop the end cap and piston out through the back of the valve.
6.1.3 Remove the O-rings (3) from the piston. Using your fingers, squeeze the O-rings (3)
up to be able to slide a plastic O-ring pick under the O-ring and pull it off the piston.
Do not use a sharp pick which may scratch or damage the O-ring grooves on the
piston. The polyurethane detent O-ring (4) is a split O-ring and can easily be pulled
off the piston. Discard the used O-rings.
6.1.4 Clean and inspect the piston (2). Replace if there is any wear or damage.
6.1.5 Clean and inspect the control block (1) bore. Replace if there is any wear, corrosion,
or damage.
6.1.6 Inspect the bushing (5) for corrosion or damage. If it needs replaced, use the .495
diameter pin and push out the bushing (5) using an arbor press.
6.2 Rebuild
6.2.1 If the Bushing (5) was removed, it must be pressed into the Control Block (1) using
an arbor press. Retaining compound is recommended but do not get compound in
the bore of the bushing (5) and clean off all excess compound after assembly.
Ensure that the bushing (5) starts straight and presses flush with the thread face of
the control block (1).
6.2.2 The Detent O-ring (4) is a white polyurethane O-ring. Use a razor blade and cut the
O-ring in one spot. The cut location is not critical.
6.2.3 Install the split Detent O-ring (4) onto the Piston (2) in
the location as shown in Fig. 3.
6.2.4 Install the other O-rings (4) onto the Piston (2) in the
locations as shown in Fig. 3.
6.2.5 Lubricate all O-rings (3) using low temperature silicone
lubricant. Ensure that O-rings are compatible with any
airline conditioner/antifreeze.
6.2.6 Insert the piston (2) with all O-rings into the Control
Block (1). Be careful when inserting the piston to
prevent any O-ring damage.
6.2.7 If attaching to a panel, insert the Control Block into the panel and thread on the panel
Jam Nut (6). Apply thread lock compound to the threads to prevent vibration from
loosening the nut.
6.2.8 Apply thread lock compound to the piston threads and thread on the Flange nut (7)
until it bottoms out on the piston (2). Thread the control knob (8) down to the flange

Corroded bushing (5) or control block (1).
Investigate reason for corrosion. Harsh cleaning
solutions or incompatible airline additives should
not be used. Remove and replace bushing (5).
If the bore of the control block (1) is corroded it
is recommended to replace the entire valve.
Damaged or bent piston (2).
Replace piston (2) but also inspect bore of
bushing (5) and control block (1) to see if they
are also damaged.
O-rings (3) swelled.
Investigate reason for O-Ring swelling.
Incompatible airline additives should not be
used. Product may be leaking into airline from
one of the Emergency Valves or Air Manifold.
See specific problem below: Product of cargo
tank leaking from exhaust port (liquid/fumes).
O-rings (3) damaged.
Investigate reason for O-rings (3) damage.
Burrs or sharp edges inside bore should be
removed without damaging sealing surface prior
