Installation and Sourcing Notes
Confirm the outside diameter against the actual cavity or bore dimension. The outside diameter does not directly equal the pipe size.
Check the installation thickness, retention structure, and sealing arrangement before placing an order.
Provide cavity dimensions, target flow and pressure, expected quantity, and destination market for accurate model selection and sample review.
Common Questions
Can I select a model by matching the outside diameter to the pipe size?
No. The outside diameter does not equal the pipe size. Check the actual cavity dimensions, thickness, and retention structure.
What information should I provide for sourcing?
Provide cavity dimensions, target flow and pressure, expected quantity, and destination market. We will review model options and sample requirements.
How should installation direction be confirmed for a short check valve?
Use the model drawing and intended system flow direction to identify inlet and outlet. Do not infer direction from appearance alone.
Can models with similar installation envelopes be interchanged?
Also check sealing, retention and service access, along with the operating requirements for the intended conditions.
How should flow restriction and non-return requirements be checked together?
This series includes combined flow-control and check-valve designs. Review target flow, installation direction and non-return requirements for the actual model and complete water path.
