Description
A swing check valve consists of a valve body, a cover, and a disc that is connected to a hinge. The disc
swings away from the valve-seat to allow flow in the forward direction, and returns to valve-seat when
upstream flow is stopped, to prevent backflow. The valve is equipped with either a lever & weight, an air
cushion with lever & weight, or a lever & spring to assist with closing the valve.
Handling and Storage
Lifting the valve improperly may damage it. Do not fasten lifting devices to the actuator or through the
seat opening in the body. Lift the valve with slings, chains or cables fastened around the valve body, or
fastened to bolts or rods through bolt holes in the flanges.
If installation will be delayed, place valve indoors in secure, weather tight storage. If temporary outside
storage is unavoidable, make sure a vermin proof rain cover (water shedding tarp, etc.) is secured
around/over the equipment to keep off rain and mud. Skid and set the assembly on a flat, solid, and
well drained surface for protection from ground moisture, runoff and pooled rain water.
Installation
•The APCO CVS-EDV Swing Check Valve may be installed in a horizontal or vertical position
(with the flow upward). In either case, the Counterweight Arm should be set in horizontal
position. Unless otherwise specified, the valves are shipped for horizontal installation.
oSee Figure 3 and 4 for component identification. On Lever and weight valves, to change
the counterweight arm position from horizontal to vertical installation, unscrew Lever Arm
to Shaft Set Screw (B57), remove Counterweight Lever Arm Washer (B56), loosen the
Lever Weight Assembly Set Screw (B55), slide the counterweight arm assembly off the
Shaft (A13), rotate the counterweight arm assembly and slide it back onto the Shaft
(A13) using the appropriate keyway shown in Figure 1.

Installation (Continued)
•Before installation, remove foreign material such as weld spatter, oil, grease, and dirt from the
pipeline.
•Prepare pipe ends and install valves in accordance with the pipe manufacturer’s instructions for
the joint used.
Do not deflect the pipe-valve joint. Minimize bending stresses in the valve end
connection with pipe loading.
If excessive seat leakage occurs during start-up, recheck the installation and
eliminate any distortion to the valve body.
•Ensure the valve and pipeline flanges are concentric to ensure proper flange sealing and seat
leakage control.
•Tighten the flange bolts or studs in a crisscross pattern a minimum of four stages.
Fusion/Powder Coated Valves
Valves with fusion/powder coated exterior paint require flat washers to be installed
under the flange nuts when installing the valve to the pipeline flange to prevent the
paint from cracking or chipping.
Maintenance
It is suggested that these valves, which do not require routine scheduled maintenance, be included as
part of the normal facility equipment inspections for any malfunction while under normal usage
conditions.
Shaft Packing Adjustment
Packing adjustment may be needed to optimize packing life on initial start-up.
These valves may open or close, swinging the counterweight/spring lever arm without
warning due to flow changes from pumps starting and stopping. Servicing or working
around these valves while the pipeline is under pressure can cause personal injury or
equipment damage.
Workers must be cautious when working around these valves. Relieve pipeline pressure
and lockout the pumps before servicing the valve.
Tighten the Gland Nuts (A26) (see Figure 3) evenly only until the packing leak stops.
Caution: Do not over-tighten Packing Gland. Valve can remain open during operation if packing is too
tight. After packing adjustments are made and pipeline is pressurized, visually inspect valve stroke to
ensure proper operation.
Note: Do not continue tightening after leak stops. If packing leak cannot be stopped by tightening the
gland nuts, the packing must be replaced.

Maintenance (Continued)
Shaft Packing Replacement
Removal of the valve from the line for shaft packing replacement is not required as long as the shaft is
accessible.
1. Relieve the pressure in the pipeline and close the valve.
2. If needed, remove Counterweight Lever Arm Fabrication (B54), spring Lever Arm Fabrication
(B33 or B85) or Cushion Lever (B88). Then, remove the Gland Nuts (A26) and Gland (A25)
from Shaft (A13).
3. Remove Long Flat Key (B78) from extended shaft.
4. Remove the V-Type Packing Sets (A23) with a flexible packing hook or similar tool. Clean the

5. Obtain the proper size packing from the parts list. Cut the packing rings to fit around the shaft.
Install one ring at a time. Make sure it is clean and has not picked up any dirt in handling before
installing it. Lubricate I.D. of each packing ring. Each ring should be firmly seated with a tamping
tool. Do not depend on the packing gland entirely to seat the set of rings properly. This practice
will jam the last rings installed but leave the first ones loose in the box.
6. See “Shaft Packing Adjustment” section to adjust packing after replacing.
Disc Seat Replacement
Servicing the valve while the pipeline is under pressure can cause personal injury or
equipment damage. Relieve pipeline pressure before servicing the valve.
1. Relieve the pressure in the pipeline and close the valve.
2. Remove Seat Retaining Ring (A16) from Disc (A10).
3. Remove old Disc Seat (A15) and replace with new Disc Seat.

Operation
The flow from the pump opens the Disc (A10) and raises the counterweight assembly. If the valve is
equipped with an air cushion, the cylinder piston is pulled upward, drawing air freely into the Pneumatic
Cylinder (B68) through the Flow Control Valve (B67).If the 3-14” valve is equipped with a lever &
spring, the spring (B34) is extended by the Lever Arm Fabrication (B33) raising up. If the 16-30” valve is
equipped with a lever & spring, the spring (B86) is compressed by the Lever Arm Fabrication (B85)
raising up, lifting the Spring Shaft (B39), which in turn pulls the Spring Tension Plate (B79) which the
Spring (B86) is seated on.
When the pump is shut off, the decreased flow allows gravity to close the Disc (A10) towards the Body
Seat Ring (A5). For valves equipped with a lever & weight, the Counterweight (B60) causes the Disc
(A10) to close faster or slower depending on its position along the Counterweight Arm (B59). For valves
equipped with an air cushion, the closure speed can be dampened by the Pneumatic Cylinder (B68).
As the Disc (A10) closes, the cylinder piston is pushed downwards and the compressed air can only
escape through the Flow Control Valve (B67) on the bottom of the cylinder. The exhausting air can be
adjusted with the Flow Control Valve (B67) to suit the best performance for the installation. For 3-14”
valves equipped with a lever & spring, the stored energy in the extended spring (B34) causes the Disc
(A10) to close in addition to weight of the disc. For 16-30” valves equipped with a lever & spring, the
stored energy in the compressed spring (B86) causes the Disc (A10) to close in addition to weight of
the disc.
System static pressure (downstream of the swing check valve) keeps the Disc (A10) and Disc Seat
(A15) closed and seated against the Body Seat Ring (A5).
Closure Speed Control Adjustment (Valves with Lever & Weight)
•Faster Disc closing - Move Counterweight (B60) away from the Shaft (A13).
•Slower Disc closing – Move Counterweight (B60) towards Shaft (A13).
Closure Speed Control Adjustment (Valves with Air Cushion)
•Increase cushioning - Turn adjusting screw of Flow Control Valve (B67) clockwise.
•Decrease cushioning - Turn adjusting screw of Flow Control Valve (B67) counterclockwise.
Start-up Procedure
1. Ensure the Counterweight Arm (B59) is horizontal.
2. Throttle down mainline isolation valve (furnished by others) on discharge side of Swing Check
Valve to approximately 1/3 open to prevent severe slamming during initial pump shutdown
testing.
3. Position Counterweight (B60) midway on the lever and lock in place.
4. If valve has an Air Cushion: Unlock Flow Control Valve by turning Flow Control Valve lock nut
counter-clockwise. Turn Flow Control Valve adjustment screw two (2) turns counterclockwise
from fully close position. Lock Flow Control Valve by turning Flow Control Valve lock nut
clockwise. (See Figure 2.)
5. Start and stop pump and observe rate of closing.
