DIRECT ACTING

INSTALLATION

Typical installations Figures 1 through 5. Follow sketch
applicable to equipment in use. Temperature Pilot may be
installed in any position. See note regarding liquid
operating mediums.

1. Control valve piping in figures are schematic. Consult

control valve instructions for proper piping details.

2. Location of Thermal Tube – Locate thermal bulb a

minimum of 6” from nearest heating or cooling coil.
DO NOT place in direct path of heating or cooling
fluids in injection systems. Full length of thermal tube
must be in contact with heated fluid at a point where
true changes in temperature will be felt immediately.
See Figure 5 for shell and tube heaters
(Instantaneous).

3. Thermometer – Position thermometer in immediate

area of thermal tube indication of signal temperature.

4. Location of Temperature Pilot – Temperature Pilot

may be installed as far as 50’ from the control valve.
However, in heat exchanger applications control valve
should be close enough to the heater to prevent
existence of an excessive reservoir of heating fluid
between valve and heater which will pass through
heater, after valve closure, causing override.

5. Liquid Operating Mediums – Elevation between

temperature pilot and control valve should not exceed
10’ when liquid is used as operating medium.

NOTE: New type covers have two directional arrows both
of which indicate “WARMER”. However, the LEFT side of
cover is marked “D-TYPES” and the right side is marked
“R-TYPES”. To INCREASE controlled temperature
setting, turn the knob to the left (counter-clockwise) for
“D-TYPES” and to the right (clockwise) for “R-TYPES).

OPERATION

NOTE: Start initially with all stop valves closed.

1. Open operating medium supply line. Adjust pressure

reducing valve to supply proper operating pressure to
temperature pilot. See Figure 6 for correct values.

2. Turn adjusting screw knob (46) to supply sufficient

operating medium pressure to control valve to bring it
into opening position. See Figure 6 for values and
reference notes on the particular control valve in use.

3. Open inlet stop valve wide. Partially open outlet stop

valve to permit flow of heating or cooling fluid. Start
flow of fluid to be heated through heater.

4. Adjust temperature pilot to supply sufficient operating

pressure to move control valve to wide open position.

5. Observe temperature rise of fluid under control. When

desired temperature is reached, adjust operating
pressure to control valve by turning adjusting screw
knob (46) until valve just closes.

Increasing/Decreasing Temperature Setting - To
increase or decrease temperature setting turn adjusting
screw knob (46) carefully as indicated by direction of
arrow on cover for type pilot shown.

6. Check controlled temperature after a period of

operation. Readjust adjusting screw knob (46)
carefully if it is necessary to change temperature
setting.

NOTE: Final adjustment are made best when apparatus is
operating under normal load.

7. After adjustments are completed tighten lockscrew (3)

just enough to provide sufficient drag to prevent
adjusting screw knob (46) from moving due to
vibration.

WIDENING PROPORTIONAL BAND –
RTP, DTP, etc. See Figure 8

When making initial adjustments for temperature setting in
RTP, DTP, etc. types start with the knob fully clockwise
(narrowest band setting). If an unstable condition appears
in the system, indicating need for widening of proportional
band, turn knob (41) slowly in direction of arrow on knob
(41) to widen proportional band until system stabilizes. (1­1/4 turns produce widest band.)

NOTE: Readjust set point slightly as desired by turning
adjusting screw knob (46) as in Step 2.

To turn system off first close outlet stop valve then inlet
stop valve.

NOTE: With GP Class Control valves relieve operating
pressure from diaphragm before closing inlet stop valve.

To turn system on with temperature set open inlet stop
valve then slowly open outlet stop valve.

MAINTENANCE

(Refer to figures below or appropriate drawings available
on request.)

DISMANTLING

1. Remove cover screw (12) and cover (6). Take out

fulcrum pin (26), lever (11) and lever spring (7). In D
types remove lever spring screw (8) also.

2. Take out diaphragm plate screws (3), diaphragm plate

(1) and diaphragm complete (2) (In RTP, DTP, etc.
types take out spring (43) also). Lift out plunger (20)
and rod (22). To remove rod from tube in D types,
body (5) must be disassembled from base (28) first, by
removing screws (27). (This is only necessary when
rod, plunger or tube must be cleaned or replaced.)

3. Loosen and remove pilot valve plug (24), gasket (25)

and pilot valve spring (37) (in R and D Types)

In RTP, DTP, etc. types proportioning band screw
(39), pilot valve plug (24), “O” ring (40) and knob
(41) are a subassembly. When pilot valve plug is
removed from body the other parts will follow.
Disassemble proportional band screw from plug.
Clean all parts, replace “O” ring if necessary and
reassemble parts.

CLEANING

Clean all parts including body with an approved solvent.
Make sure body ports are clear. Use crocus cloth to
remove encrusted material. Replace any badly worn or
damaged part.

REASSEMBLY

1. Reassemble pilot valve (23), pilot valve spring (37),

gasket (25) and pilot valve plug (24) to body. In RTP,
DTP types these parts comprise a subassembly (pilot
valve being replaced by the proportional band screw).
Tighten pilot valve plug.

2. Reassemble rod (22) and plunger (20) in tube with

recessed end over end of rod. Install diaphragm
complete (2) in body recess with disc end toward
nozzle. In RTP, DTP, etc. types make sure that small
valved portion of disc enters orifice of nozzle. In D
types reassemble body to base.

adjustable proportional band mechanism

3. Place diaphragm plate (1) on diaphragm complete

(raised face downward). Insert screws (3) and turn
down into body threads just enough to hold diaphragm
plate snug. DO NOT overtighten as this will cause
snap in diaphragm with possible erratic response
resulting.

4. In R and RTP, etc. types assemble lever spring (7) and

lever (11) to body, then insert fulcrum pin (26) in
holes in body and lever. Test action of lever. It should
be smooth and free. Check lever clearance as
described under “Setting Lever Clearance”*.

In D, DPT, etc. types assemble lever (11) to body and
insert fulcrum pin (26). Test action of lever. It should
be free and smooth. Check lever clearance as
described under “Setting Lever Clearance”*. Then
assemble lever spring (7) on lever, insert screw (8)
through spring and into diaphragm plate (1). Tighten
screw.

* If lever clearance is correct DO NOT DISTURB
adjustment.

5. Reassemble cover (6) to body. Insert screw (12).

Tighten. Reconnect operating medium tubing (if
disconnected). Readjust as described under
“OPERATION”.

HOW TO SET LEVER CLEARANCE

NOTE: Lever setting is factory set. Do not disturb if
dimension corresponds to that shown below for the
particular temperature pilot.

* To adjust when necessary, subject tube of temperature
pilot to a temperature of approximately 70°F then turn
adjusting screw (9) outward until it is clear of diaphragm
complete (2) and proceed as follows (See Figure 7).

LEVER CLEARANCE ADJUSTMENT

NOTE: Thermo tube must be at room temperature while
making lever clearance adjustments.

For Reverse Acting Types – R, RT, RTP, etc.

1. Loosen temperature adjusting knob lock screw and

remove knob.

2. Remove cover screw and lift off cover.

3. Move temperature adjusting screw upward until

bottom of screw is no longer in contact with
diaphragm.

4. Check dimension “A” with a scale. Distance from

bottom of lever to top of diaphragm plate should be
5/32”.

5. If dimension is incorrect, loosen adjusting screw lock

nut and screw adjusting screw into lever toward
plunger plug if dimension is greater than 5/32” or
away from plunger plug if dimension is less than
5/32”. Check clearance. Repeat procedure until 5/32”
clearance is obtained. Hold adjusting screw in place
with a screwdriver and tighten lock nut. Replace cover
and cover screw.

6. Adjust pilot for required control temperature. Replace

temperature adjusting knob with pointer in center
position of cover and tighten adjusting knob lock

7. Loosen lever adjusting screw lock nut and screw

adjusting screw into lever toward plunger plug if
dimension is less than 11/32”. Replace lever and
fulcrum pin. Hold lever tip down so that adjusting
screw rests firmly against end of plunger plug. Check
clearance. Repeat procedure until a clearance of
11/32” is obtained. Hold adjusting screw in place with
a screwdriver and tighten lock nut.

8. Replace lever, fulcrum pin and retaining washer, lever

spring and lever spring screw. Tighten lever spring
screw. Replace cover and cover screw.

9. Adjust pilot for required control temperature. Replace

temperature adjusting knob with pointer in center
position of cover and tighten adjusting knob lock
screw.

ADJUSTING PROPORTIONAL BAND
MECHANISM

NOTE: This adjustment is factory set with and air supply
pressure of 20 psig. Adjustment should not be disturbed
unless replacement of a part is necessary in the
proportional band mechanism or if the inlet supply
pressure is changed to a higher value. If it is necessary to
disturb adjustment, readjust in the following manner.

1. Loosen set screw in knob (39). Remove knob from

proportional band screw (23).

2. Supply desired operating pressure to temperature

pilot. Then turn proportional band screw (23) inward
toward seat until all air flow ceases through pilot. (Do
Not squeeze screw against seat.)

3. Back proportional band screw (23) away from its seat

the number of degrees shown in curve Figure 9 for the
particular supply pressure in use.

4. Replace knob (39) on proportional band screw (23)

with pointer against ping in plug (24) in a fully
clockwise position.

5. This setting will produce minimum proportional band.

Turning knob (39) counter-clockwise, widens
proportional band. Maximum width of band is reached
when pointer is turned counter-clockwise the percent
of full rotation shown in curve Figure 10 for the
particular air supply pressure in use.

6. Adjust for desired temperature and width of band as

described under “Operation”.
