The following is a typical example of a tank filling/deaerator application using properly sized,
selected, and maintained Warren Controls Level Controls. Demand for water reduces the liquid
level in the tank. The [A] 377 Float Cage opens the [B] 322L or 326L Lever Valve to supply intake
water to the tank. When the water reaches the desired level the float cage closes the lever valve
to accurately maintain the liquid at the desired level. Deaerators, tanks with steam blankets,
produce additional liquid as the steam condenses. The [C] 313 Overflow Trap traps and relieves
this condensate through its internal pilot without the steam blanket escaping. Overflow can occur
if the water entering the tank exceeds its capacity. The 313 Overflow Trap relieves the overflow
through its internal single seated main stage valve. Falling liquid levels and condensing steam
can cause a vacuum that can damage the tank. The [D] 200 Vacuum Breaker opens to admit outside
air to relieve the vacuum in the tank. Warren Controls Level Controls are also used on boiler make-up
water tanks and many other storage tank applications.

 A rising or falling liquid level in a tank raises or lowers the float ball in the 377 Float Cage.This motion is converted
to force through the rotation of the float rod and lever arm (lever) about the float shaft assembly. The force is
transmitted through the turnbuckle assembly to the lever actuator of a 326L or 322L Lever Valve where it is used
to open or close the valve. Fully immersed in water the float can exert approximately 150 inch-pounds of torque
onto the float arm shaft. The maximum rotation of the float arm shaft is 23°.

DIMENSION L - RISING LEVER OPENS VALVE
The 377 when installed according to these guidelines will provide a maximum water level in the tank that is 2-1/4 inches below the top of the
377. The 377 Float Cage must be installed with the axis through the 1-1/2 NPT pipe connections oriented vertically. The 326L or 322L Lever
Valve is located above the 377 in rising lever opens valve applications, and below the 377 in rising lever closes valve applications. The lever
valve must be installed with the fluid flowing in the correct direction. For proper operation in all applications, lever valves must be piped
according to the corresponding flow arrows, or inlet markings present on each valve (See Information Present on 326L Lever Valves section
or Information Present on 322L Lever Valves section for location of important information on valve). The lever valve must be installed in the
vertical position with the stem pointing upward. When the maximum desired water level in the tank is reached the 377 closes the lever valve
stopping the flow of water into the tank. When the lever valve is closed its lever is horizontal, the turnbuckle is vertical, the end of the 377
lever connected to the turnbuckle is at its lowest point in rising lever opens valve applications and at its highest point in rising lever closes
valve applications. Clearance must be allowed for each turnbuckle connection and lever rotation. There are four possible turnbuckle con-
necting holes on the lever.

INSTALLATION GUIDELINES
BEFORE YOU BEGIN
The guidelines presented here are for a typical tank filling application utilizing a 377 Float Cage and a Warren Controls Lever Valve. As
shown in the Typical Installation Drawings the 377 closes the Lever Valve when the water in the tank reaches the desired level. Since there
are numerous possible working configurations it is necessary for you to determine where the 377 and Lever Valve will be located before
you install them. The INSTAL LATION GUIDELINES are presented for this purpose. Please read all guidelines thoroughly before
you begin.

INSTALLATION GUIDELINES CONTINUED
Corresponding turnbuckle connections on the 377 lever are designated by the dimension“L”. Dimension “L”is the distance in inches from
the center of the rocker arm to the point where the turnbuckle connects to the 377 lever. (See diagrams and tables) The 377 lever may be
moved in the rocker arm if the hole for the turnbuckle connection is not present at dimension “L”. To move the 377 lever loosen the lever
capscrew and slide the lever until a hole is in the correct location. Finally to facilitate the turnbuckle connection the lever valve lever may
be rotated 360o around the valve stem. To rotate the lever loosen the yoke locknut, lift the lever slightly, and turn the lever to the desired
position. Tighten the locknut to hold the lever in position. The turnbuckle must then be adjusted so the clevises line up with the levers.
Before mounting the Lever Valve and 377 the water level in the tank must be at least 19 inches below the maximum desired level. Do not
apply water pressure to the Lever Valve inlet until you are ready to test it.
Mount the 377 according to the INSTALLATION GUIDELINES.
Mount the 326L or 322L Lever Valve according to the INSTALLATION GUIDELINES.
Remove the weights from the levers. Move the lever valve lever full up and down to break the packing friction so the lever moves
smoothly. Connect the turnbuckle to the correct hole on the lever valve lever. Push the end of the 377 lever farthest away from the float
ball down until you hear the float ball hit the top of the 377. With the lever valve lever down as far as it will go (horizontal) for rising lever
opens valve applications or up as far as it will go (horizontal) for rising lever closes valve applications adjust the turnbuckle length and
connect the turnbuckle to the 377 lever at the correct dimension“L”. Shorten the turnbuckle so the float ball just misses hitting the top of
the 377 (you do not hear it hit the top). Make sure that the levers and turnbuckle move freely without binding or locking up then tighten
the turnbuckle jamnuts.
Position the weights as necessary on the levers to balance the assembly. Readjust the weights until the lever valve lever just moves on its
own from horizontal to full up for rising lever opens valve applications or from horizontal to full down for rising lever closes valve applica-
tions. Tighten the weight capscrews to hold the weights in position. (You may only need one weight)

Apply water pressure to the lever valve inlet. Water should pass through the Lever Valve and enter the tank. The water level in the tank
should rise to the maximum desired level then the 377 should close the lever valve stopping the flow of water into the tank.

Damaged or worn parts can decrease performance and shorten the life of the float cage.
A damaged float ball and/or float rod can result in poor control and poor shut-off of the attached lever valve.
A damaged or worn float arm shaft with elbow can result in poor control and poor shut-off of the attached lever valve, and
can also cause damage to the bonnet and o-ring.
A damaged or missing e-ring can result in damage to the float rod, float arm shaft, o-ring, and linkage.
A damaged or worn bonnet can result in poor control and poor shut-off of the attached lever valve, and can also cause dam-
age to the float shaft and o-ring.
A damaged or worn o-ring can result in poor control and poor shut-off of the attached lever valve, and can also cause damage
to the bonnet and float shaft.
A damaged or worn gasket or o-ring can cause external leakage resulting in damage to surrounding equipment.
A damaged lever arm or turn buckle assembly can result in poor control and poor shut-off of the attached lever valve.

326L and 322L Lever Valves have self-adjusting packing and require no external adjustment. 326L and 322L Lever Valves with
stainless steel trim have TFE V-ring Packing. 322L Lever Valves with bronze trim have EPDM Lip Packing. If the valve has self-
adjusting packing and a packing leak is observed replace the packing and if necessary the stem and plug assembly.
PACKING ADJUSTMENT
Damaged or worn parts can decrease performance and shorten valve life.
Damaged or worn packing parts including as applicable the packing, bearings, spring, and other bonnet parts can cause
a packing leak resulting in damage to the actuator and surrounding equipment. Damaged or worn packing parts can also
cause increased hysteresis resulting in poor control.
Damaged or worn trim parts including as applicable the plug, stem, seat ring(s), piston, pilot retainer, and o-ring can cause
increased hysteresis, poor control, excessive internal leakage, and poor shut-off. Damaged or worn trim parts can also cause
damage to the packing parts resulting in a packing leak.
Damaged or worn body gaskets can cause external leakage resulting in damage to the actuator, accessories, and surround-
ing equipment.
Should parts become worn or damaged, parts kits are available. Repack Kits are available to replace the packing. Repack/
Inspection Kits are available to allow the valve to be opened for inspection of its internal parts. Rebuild/Repack Kits are avail-
able to completely rebuild/ overhaul the valve. Parts kits come with complete step-by-step instructions. Each kit has its own
part number. Please provide the valve’s serial number to ensure getting the correct kit part number and correct parts.
