INTRODUCTION
WAFER CHECK VALVE IOM GUIDE Page 3 of 8
The APOLLO ® Iron Wafer Check valves provide full flow capabilities. It provides dependable and economical protection against reverse flow. It can reliably be installed in most plumbing and heating systems (or building service piping).
Each valve is classified by its pressure rating. All valves designated as Class 125 comply with MSS SP-71 Standard Practice.

INSTALLATION
APOLLO
Wafer Check Valves are designed for use between the faces of ANSI 125 and
150 pound flat flanges. Raised faced flanges are not recommended.
To improve service life and efficiency, Wafer Check Valves are to be used in a steady flow application. Wafer Check Valves are not recommended to be used in an application where physical or thermal shock-load may be present.
Installation Instructions
Step 1. Check to make sure that the pipe flange and valve sealing faces are clean and free from any debris (pipe scale, welding slag, etc.).
Step 2. Check the valve nameplate to ensure that the pressure and valve materials are correct for the application.
WARNING! – APOLLO ® Wafer Check Valves should never be installed where service conditions could exceed the valve ratings. Failure to heed warning may result in personal injury or property damage.
Step 3. Place the valve between the two flanges of the pipe and put the seal gasket between the valve flange and the pipe flange; make sure that it is correctly positioned.
Horizontal Installation: Check Valve should be installed with rib perpendicular to the flow. See Figure 2 for Correct Horizontal Positioning.
Vertical Installation: Check Valve can only be installed vertically with flow direction upward. Arrow on body indicates the correct direction of flow. Valve should be installed with rib parallel to the incoming horizontal piping, so that it creates equal loading on the plates. See Figure 3 for Correct Vertical
Positioning.
Step 4. To improve service life and efficiency, check valves should be installed 5 to 10 pipe diameters from any tees, elbows, pumps, swages, expansions and reductions.
Step 5. Assemble the valve to the pipe using properly sized bolts for application. See
Table 4. Progressively tighten to the torque value recommended by the seal gasket provider. See Figure 4 for recommended method.
After the valve installation on the line and before the line pressurization, the following activities must be performed:
- the packing bolts must be verified for tightness, DO NOT OVERTIGHTEN.
- the valve must be fully stroke operated

OPERATION
APOLLO ® Iron Wafer Check valves are designed to prevent reverse flow in piping systems.
They are comprised of two spring loaded half-moon discs that open and close in response to the inlet flow pressures and reverse flow pressures. When the required inlet pressure is present disc will open. When there is inadequate inlet pressure the disc will close preventing any reverse flow in the piping system.
MAINTENANCE
APOLLO ® Iron Wafer Check valves are designed for extended service with minimal wear and servicing. Replacement parts are not available.
WARNING! – The pipeline on either side of the valve MUST be depressurized and drained prior to repair.
Valve Leakage
Valve should be periodically inspected for leakage. If the valve is found to be leaking, check the flange bolt torque and the flange gasket. If leakage is still present, valve may need to be removed to inspect the seating surfaces for imperfections.
No Flow
Inspect the Check Valves to make sure flow direction matches the directional arrow that is cast on the body of the Check Valve.
Slamming
Check Valve will need to be removed to verify that the spring is providing the proper tension.
Vibration
Confirm that the check valve is 5 to 10 pipe diameters from any turbulence producing devices (tees, elbows, pumps, swages, expansions and reductions). Vibration can also be caused if the flow rate is above the recommended range.
