Gray PVC Ball Check Valve with Solvent-Weld Socket
The gray PVC ball check valve is a component of a sewer installation that allows the medium to flow in only one direction and prevents backflow. A free-moving ball is located inside the body—it rises under the pressure of the flow and drops to shut off the return flow. The U-PVC body, EPDM ball, and seals provide resistance to wastewater and typical sewage media.
Who it is for
-
Drainage installers – the valve protects the installation against wastewater backflow from a vertical stack or collector.
-
Pumping station and drainage contractors – protection for the pump and pipeline against reverse flow.
-
Homeowners with gravity sewer systems – protection against flooding when the network backs up.
-
Plumbing wholesalers and service providers – simple solvent-weld or threaded installation in typical sizes.
Applications
The PVC ball check valve is used in sewer installations where wastewater and medium backflow must be prevented. It is installed on the pipeline in accordance with the flow direction, in a solvent-weld or threaded version. The ball inside the body automatically opens and closes the flow without the need for control.
It is suitable for pumping stations, drainage systems, and household sewer installations exposed to reverse flow. The size is selected according to the pipeline diameter. The gray PVC ball check valve is available in sizes 1¼", 1½", and 2".
Features of the PVC ball check valve
The valve operates using a free-moving ball enclosed in the body. Flow in the correct direction lifts the ball and opens the passage for the medium, while a reduction or reversal of flow causes the ball to drop onto the seat and shut off the return flow. Operation is fully automatic and requires neither power nor manual control.
The body is made of U-PVC, while the ball and seals are made of EPDM, which is resistant to wastewater and typical sewage media. The valve is available in a solvent-weld version (for bonding, without a thread) in sizes from 1¼" to 2", and in a threaded version in size 2". The gray version has an opaque body.

Frequently asked questions (FAQ) – gray PVC ball check valve
What is a PVC ball check valve used for?
The PVC ball check valve allows the medium to flow in only one direction and prevents backflow in a sewer installation. In this way, it protects pumps, pipelines, and rooms from the effects of reverse flow. It operates automatically without a power supply.
What is the difference between the gray and transparent versions?
The gray version has an opaque body, while the transparent version has a clear body that allows the operation of the ball and the flow to be observed. Both versions have the same construction and specifications. The transparent version facilitates visual inspection and the detection of contaminants without disassembly.
How does a ball check valve work?
A free-moving ball is located inside the body. Flow in the correct direction lifts it and opens the passage for the medium, while a reduction or reversal of flow causes the ball to drop onto the seat and shut off the return flow. The entire process is automatic.
Is the valve suitable for wastewater?
Yes. The U-PVC body, EPDM ball, and seals are resistant to wastewater and typical sewage media. The valve is specifically designed for sewer installations.
How do I select the size and installation method?
The size is selected according to the pipeline diameter—1¼", 1½", and 2" sockets are available. The solvent-weld version is available in sizes from 1¼" to 2", while the threaded version is available in size 2". The maximum operating pressure is PN10.
Where can I buy an IBO PVC ball check valve?
As the manufacturer, we do not sell directly. The IBO PVC ball check valve can be purchased from our commercial partners, plumbing wholesalers, and authorized online distributors. The version and size should be selected according to the installation.
What is the warranty on the IBO PVC ball check valve?
IBO – 24 months (2 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service. For questions about product selection, it is best to contact an authorized distributor.
