Products Description

The Singl union ball check valve uses a freely moving ball inside the valve body for sealing. It is a type of automatic valve and is used to prevent backflow in the pipeline system. This valve is particularly useful in systems that are maintained and easily serviced. The following is an overview of the features, applications and benefits of  single union ball check valves:

Singl union ball check valve Features

Material: Valve materials are usually made of PVC, transparent PVC, CPVC, PPH, and other materials. Offers excellent resistance to corrosion and chemical abrasion and is suitable for use with a variety of fluids, including mildly corrosive fluids.

Single joint design: With a joint connected at one end, installation and disassembly are easy without disassembling the entire piping system. This design facilitates quick maintenance and inspection.

Ball Mechanism: The ball moves freely on the internal rails of the valve body and forms a seal with the valve body to prevent backflow when the flow is stopped or reversed. When forward pressure is applied, the ball moves away from the seat, allowing flow.

Clear Body Option: Some models may include a clear body section that allows visual confirmation of ball position and operation, aiding in troubleshooting and maintenance inspections.

Installation: The union end allows the valve to be quickly installed or removed, which is very advantageous for systems that require frequent maintenance.

Direction: Please refer to the direction of the arrow on the valve during installation to ensure that the direction of the fluid is consistent with the direction of the arrow.

Water Treatment Systems: Ideal for systems that handle non-corrosive fluids and require easy maintenance.

Chemical Treatment: Due to its chemical resistance, it is used in treatment systems involving various chemicals.

Aquariums and Pools: Commonly used in aquarium filtration systems and swimming pools to prevent backflow of water.

Easy Maintenance: The single-tube connector design simplifies maintenance, making it easier to replace or clean valves without lengthy system downtime.

Durability: Construction ensures long-term durability and resistance to chemical and physical wear and tear.

Cost-Effectiveness: PVC or CPVC valves are generally more economical than valves made from more exotic materials, but still offer good chemical resistance and durability.

Periodic Inspections: It is important to inspect the valve regularly and clean the ball and seat to ensure no debris or buildup could prevent proper sealing.

Operational Inspections: Regular operational testing can help ensure proper valve operation, especially in critical applications where backflow can cause serious problems.

Single union ball check valves are an excellent choice for applications requiring reliable backflow prevention, easy maintenance, and chemical resistance while being cost-effective and easy to operate.
