Gray PVC Ball Check Valve with Solvent-Weld Socket
The gray PVC ball check valve is a component of a sewage system that allows the medium to flow in only one direction and prevents backflow. Inside the body is a free-moving ball that rises under the pressure of the flow and drops to shut off the returning medium. The U-PVC body, EPDM ball and seals provide resistance to sewage and typical wastewater media.
Who it is for
-
Sewage system installers – the valve protects the installation against sewage backflow from a vertical pipe or collector.
-
Pumping station and drainage contractors – protection of the pump and pipeline against reverse flow.
-
Owners of homes with gravity sewage systems – protection against flooding when the network backs up.
-
Plumbing wholesalers and service providers – simple solvent-weld or threaded installation in standard sizes.
Applications
The PVC ball check valve is used in sewage systems where backflow of sewage and other media 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 domestic sewage 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 stoppage or reversal of flow causes the ball to drop onto the seat and shut off backflow. Operation is fully automatic and requires neither a power supply nor manual control.
The body is made of U-PVC, while the ball and seals are made of EPDM, which is resistant to sewage and typical wastewater media. The valve is available in a solvent-weld version (for bonding, without threads) 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 the sewage system. 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 identical construction and specifications. The transparent version makes visual inspection easier and allows contaminants to be detected without disassembly.
How does a ball check valve work?
There is a free-moving ball inside the body. Flow in the correct direction lifts it and opens the passage for the medium, while a stoppage or reversal of flow causes the ball to drop onto the seat and shut off backflow. The entire process is automatic.
Is the valve suitable for sewage?
Yes. The U-PVC body and the EPDM ball and seals are resistant to sewage and typical wastewater media. The valve is specifically designed for sewage systems.
How do I choose the size and installation method?
The size is selected according to the pipeline diameter – sockets are available in 1¼", 1½" and 2". 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?
