2.0 Storage and Handling
2.1 Storage
2.1.1 Inside
The ideal storage location for a Proco Series 700 ProFlex rubber check valve is in a warehouse setting with a
relatively dry and cool location. Store the check valve in a vertical position on a pallet or wooden platform
similar to as shown in Figure 5 below.

2.1.2 Outside
If the rubber check valve is to be stored outside, keep the check valve protected in a waterproof crate until ready
for installation. Keep the check valve protected from any external elements such as direct UV exposure. Do not
lay other boxes on top of the check valve or check valve box.
2.2 Handling
Care should be taken when handling the Proco Series 700 ProFlex rubber check valves whether big or small to reduce the
possibility of damaging the check valve during installation. For large size check valves, special care should be taken in loading,
hoisting, and lowering; being careful not to hit adjacent equipment, forklift tines, crane cables, etc. Style 710 & 730 check valves
36” and larger are manufactured with a lifting support hole to assist in the safe and proper lifting/installation of these check
valves. The lifting support holes are not intended to support the entire weight of the check valve and care must be taken to
adequately support the cuffed or flanged end as well. Note: Proco Products, Inc. will not be responsible or liable for damage to
the rubber check valve, adjacent equipment, or injury to personnel if these steps are not taken.
3.0 Prior to Installation
3.1 Inspect the Received Check Valve
ProFlex check valves are fully inspected at the factory and are carefully packaged to arrive at the job site ready for installation.
Upon receipt of the check valve(s), inspect for damage that may have occurred during transportation and immediately contact
your transportation company to report any damage. Check the item(s) received against the packing slip to ensure that all items
have been received. For any questions or concerns about the received product contact your Agent or Proco Products, Inc. at
sales@procoproducts.com or for immediate assistance call (800) 344-3246 (US/Canada) or (209) 943-6088 (International).
3.2 Verify the System Parameters
Check the system design parameters for the application to ensure the specified/supplied Proco Series 700 rubber check valve(s)
will meet the system requirements.
3.3 Check Valve Mating Surface
Inspect the mating flange/surface to ensure that it is undamaged and clean and free of all foreign matter before installation of the
check valve. For slip-on style of rubber check valves, the mating pipe must be free of sharp edges which may damage the inside
sealing diameter of the check valve.
3.4 Safety Area
Always check your work area before installation for safety hazards which may cause injury or damage to personnel or product.
Develop and discuss a safety and exit plan for you and your fellow employees in the event of an emergency.
