Horizontal Check Valve

The Horizontal Check Valve is a critical flow-control device engineered to permit fluid flow in one direction while automatically preventing reverse flow, or backflow, within a pipeline system. Its primary function is to protect pumps, compressors, and other sensitive equipment from damage caused by pressure surges or reverse circulation when flow stops. By ensuring unidirectional flow, it maintains system efficiency, prevents water hammer, and safeguards process integrity in applications ranging from water supply and HVAC systems to industrial processing and irrigation. Designed specifically for horizontal pipeline installation, its compact internal mechanism and body orientation are optimized for space efficiency and reliable operation under varied pressure conditions.

Product Feature and Application

Application

A copper horizontal check valve, also known as a one-way valve or non-return valve, functions to prevent the backflow of medium within pipelines. The bottom valve of a water pump suction pipe is also considered a type of check valve. These are automatic valves, where the opening and closing components rely on the flow and force of the medium itself. They are primarily used in pipelines that require the medium to flow in only one direction, preventing accidents caused by reverse flow.

Feature

Material and Process: Made from high-quality copper material using a hot-forging process.

Working Medium: Suitable for various media including water, oil, and gas.

Working Temperature: Operational within a temperature range of -10°C to ≤120°C.

Maximum Working Pressure: Designed to withstand a maximum allowable working pressure (PN) of 16bar.

Installation and operation instructions

1.Straight-through lift check valves should be installed on horizontal pipelines; vertical lift check valves are generally installed on vertical pipelines, with the medium flowing from bottom to top.

2.The installation position of swing check valves is not restricted; they are usually installed on horizontal pipelines, but can also be installed on vertical or inclined pipelines.

3.When installing, ensure that the direction of medium flow is consistent with the arrow indicated on the valve body.

Maintenance

1.Regular cleaning. To avoid the influence of impurities and sediment in the pipeline on the check valve, it is necessary to regularly clean the all-copper horizontal check valve and the inside of the pipeline.

2.Note alternating cold and hot water operations. Frequently opening and closing the check valve will cause damage, so alternating cold and hot water operations should be avoided.

3.Note pressure. When using the all-copper horizontal check valve, attention should be paid to the pressure situation inside the pipeline, as excessively high pressure will have an adverse effect on the check valve. In short, the all-copper horizontal check valve is a commonly used device in pipeline systems, and its use and maintenance are very simple and easy. In actual use, users should operate and maintain according to the above requirements to ensure the use effect.
