Figure 2. Type E Main Valve Operational Schematic
Principle of Operation
The regulator is operated by initial steam or uid
pressure. It is normally closed, being held so by
initial pressure on the disc and by an internal main
spring, see Figure 2. When the pilot is opened (see
pilot instructions), initial pressure ows through the
pilot to the 8B tee. 4A bleed port restricts the ow
and pressure builds under the diaphragm and opens
the main valve. The 5A restriction elbow steadies the
operation of the regulator.
Delivery pressure feeds back through the control pipe
to the pilot diaphragm. As this pressure approaches a
balance with the thrust of the adjusting spring, the pilot
throttles the loading pressure. In turn, the main valve
takes a position established by the loading pressure
where just enough steam ows to maintain the set
delivery pressure.
Installation
▲ WARNING
Personal injury or system damage
may result if this regulator is installed,
without appropriate overpressure
protection, where service conditions
could exceed the limits given in
the Specications section and/or
regulator nameplate.
Additionally, physical damage to the
regulator may result in personal injury
or property damage due to escaping of
accumulated gas. To avoid such injury
and damage, install the regulator in a
safe location.
Under enclosed conditions or indoors,
escaping gas may accumulate and be an
explosion hazard. In this case, the vent
should be piped outdoors.

Type E

For regulator constructions with a
spring case vent, the vent should be
kept open to permit free ow of gas
to the atmosphere. Protect openings
against entrance of rain, snow, insects
or any other foreign material that may
plug the spring case vent or vent line.
All pressure equipment should be installed
in a non-seismic area; should not be
exposed to re; and should be protected
from thunderbolt (lightning) strikes.
Planning
• Locate the valve in a straight run of horizontal pipe.
• Allow headroom above the valve for access through
the blind flange.
• Provide clearance for stem withdrawal underneath.
• Prevent water hammer and erratic operation by
installing traps to provide proper drainage before
and after the valve and before secondary pressure
relief valve or control valve.
• Avoid damaging effects of scale and dirt in the pipe
lines by using a strainer as shown in Figure 3.
• Provide a 3-valve by-pass to facilitate inspection
without interrupting service.
• To eliminate excessive noise and erratic regulation
with steam and other compressible fluids, enlarge
the delivery pipe size to effect a reasonable
flow velocity at the reduced pressure. A tapered
transition is recommended.
• If possible, avoid a sharp turn close to the regulator
outlet and a bull-headed tee connection to the low
pressure main.
• Install initial and delivery pressure gages to
indicate performance.
• If the pressure rating of the delivery system or
connected equipment is less than the initial steam
pressure, provide a safety valve.
Main Valve
• Flush the piping system thoroughly to clear it of
welding beads, scale, sand, etc.
• Mount the main valve with diaphragm chamber
down and arrow on body pointing in the direction
of flow. Screwed end valves should be mounted
in unions.
Pilot
For Side Mount Construction
1. Mount the pilot on either side of the main valve by
means of 1/4 in. nipple and union provided.
2. Make this connection on the 1/4 in. pipe tap at the
inlet of the main valve as shown in Figure 4.
For Integral Mount Construction
1. Remove blind flange on pilot and mount on blind
flange of main valve using provided bolt.
2. Screw 4A bleed port fitting into the 1/8 in. pipe tap
at the outlet of the main valve body. Note bleed
orifice in this fitting is vital to operation of regulator.
Note
As a general rule of thumb, tighten
1.5 to 3 turns past hand tight all NPT
connection and use thread sealant with
a temperature range up to 450ºF / 232ºC.
3. Screw 8B tee into 1/8 in. pipe tap in pilot. Select
tap facing downstream.
4. Screw 5A restriction elbow containing restriction
orifice into 1/8 in. pipe tap on the underside of
main valve diaphragm chamber. If the initial
pressure or pressure drop is less than 15 psi /
1.03 bar, use 5B open elbow.
5. Connect tubing bends as illustrated in Figure 4.
Valves with condensation chamber are fitted up
according to Figure 4.
Control Pipe
1. Use 1/4 in. pipe for this line which connect the
pilot diaphragm chamber to the desired point of
pressure control.
2. Take the control at a point of minimum turbulence.
Avoid control immediately at the valve outlet or
after a turn.
3. When the delivery pipe expands in size, select a
spot at least 4 pipe diameters beyond the point
of enlargement.
4. Pitch away from pilot to avoid erratic operation and
excessive fouling.
5. Eliminate water pockets.
6. Locate delivery pressure gage in control pipe to
show pressure actually reaching pilot diaphragm

Type E

Figure 4. Mounting Pilot on Type E Main Valve
Start-up and Setting
△ CAUTION
Never open a reducing valve without
positive indication that the high side is
clear of condensate.
1. On pressure reducing valves like Type E, use
by-pass to fill the delivery system and raise
pressure to slightly below normal required.
2. Close pilot by releasing compression on adjusting
spring. See Figure 4.
3. Open 1/4 in. control pipe valve.
4. Crack outlet stop valve.
5. Crack inlet stop valve.
6. Blow down strainer.
7. Open inlet stop valve and gradually compress
adjusting spring until the valve opens and takes
control at desired pressure.
8. Alternately choke down on the by-pass and open
outlet stop valve until the regulator is on the line.
See individual instructions for other pilots.
Valve Setting
Valve setting is gaged at K to establish correct stem
length and diaphragm position. Dimension K is
supplied with each replacement stem. See Table 4 for
K values. For metal diaphragm valves, K is cast on the
upper face of pressure plate (key 17, Figure 7).
1. To install new stem (key 11), fasten disc (key 7)
firmly on stem with stem nut.
2. Insert stem and disc assembly in valve and screw
on pressure plate (key 17). Omit spring (13) for
this operation.
3. Hold disc on seat and adjust position of pressure
plate until valve setting K is reached.
4. Push pressure plate against stops in base
(key 16).
5. Remove disc, drop out pressure plate and stem,
drill and insert dowel pin (key 14) to lock the joint.
Grind off stem projection flush with face of pressure plate.

Troubleshooting
Failure to Open
If the main valve failed to open check the following
possible causes to properly correct the problem.
• Adjusting spring on pilot may have been
tampered with.
• Initial pressure may be down due to partially closed
supply valve, clogged strainer or other obstruction.
• Orifice in No. 5A restriction elbow may be plugged.
No. 4A bleed port fitting may have been omitted
and an open coupling substituted.
• Control pipe may be plugged. Most likely points
of obstruction are at shutoff valve and entrance to
delivery main.
• Main diaphragm may be broken. Test with air or
water before dismantling.
Failure to Close
If the main valve failed to close check the following
possible causes to properly correct the problem.
• Adjusting spring on pilot may have been
tampered with.
• Orifice in bleed port No. 4A may be plugged.
• By-pass valve may be leaking.
• On pressure regulators like Type E, the main valve
or pilot may be held open by foreign matter in seat.
To determine which valve leaks, follow these steps.
Close stop valve and 1/4 in. control pipe valve.
1. Remove bleed port bend so pilot will exhaust
to atmosphere.
2. Crack inlet stop valve. Steam will issue from
8B tee.
3. Release compression on adjusting spring to
see if pilot closes tight.
4. Open and close several times to wash seat.
Steam blowing back from bleed port means
main valve disc is held open by foreign matter.
Steam may wash the obstruction from the seat
if the valve is made to open wide. This can be
accomplished, even at light loads, if the control
point is beyond the outlet stop valve.
5. Reassemble bleed port bend and place
regulator in operation.
6. Slowly open and close outlet stop valve.

Seat Ring Maintenance
Note
These joints should be made up with
high temperature gasket compound.
1. Remove old compound from body and seat ring
with a wire brush.
2. Apply new compound sparingly to both parts,
threads and shoulders. Let stand until tacky
before assembling.
Grinding In
△ CAUTION
Seats and discs should never require
more than the lightest touch up with very
fine (400 grit) grinding compound. Heavy
grinding will produce galling, wider
seating surface and a groove in the disc,
all of which tend to cause leakage.
3. Reface a damaged surface before attempting to
grind it in.
4. Grind sparingly.
5. Main stem (key 11, Figure 7) is slotted for rotation
with a screwdriver, valve spring (key 13) is omitted
from the assembly during grinding.
6. Slip the stem into its normal position.
7. Apply compound to the disc. Place it on the stem
and tighten with one stem nut.
Maintenance
▲ WARNING
To avoid personal injury or property
damage from sudden release of pressure,
isolate the regulator from the pressure
system and release all pressure from the
pilot and main valve before performing
maintenance operations.
Inspection
Under normal conditions, complete dismantling is not
recommended.
Check the following after operation. Then, schedule an
inspection as required.
1. Inspect for dirt collected at 4A bleed port and 5A
restriction elbow.
2. Inspect all joints for leakage. Keep bolts tight to
avoid any leaks
Main Valve Maintenance (See Figure 5)
1. Connect a source of air or water pressure
which can be adjusted by hand to the No. 5A
restriction below.
2. Apply 50 to 60 psi / 3.45 to 4.14 bar to jack
valve open and prevent stem from turning while
removing stem nuts.
3. Use penetrating oil on the threads.
