Check Valves

Check Valves

Check valves are used in pipeline systems where flow needs to move in one direction and reverse flow must be prevented.

This category includes spring check valves, ball check valves and non-return valves used in water, wastewater, drinking water, agricultural, industrial and non-corrosive liquid applications, depending on the selected valve type and operating conditions.

Available Check Valve Types

Spring Check Valve PN 10/16

Spring Check Valve PN 10/16 is a spring-assisted non-return valve used to prevent reverse flow in liquid pipeline systems.

The product information mentions use in industrial, constructional, water, wastewater, drinking water, agricultural and non-corrosive liquid applications up to 80°C. It is also used where reverse flow control and water hammer reduction are required, especially in pumping stations.

Spring Check Valve S2 PN 10/16

Spring Check Valve S2 PN 10/16 is listed as a separate spring check valve model in the check valve product range.

This model should be reviewed separately according to its product documentation before final selection.

Ball Check Valve PN 10/16

Ball Check Valve PN 10/16 is listed as part of the check valve range.

This valve type should be selected based on the required check valve configuration, pressure class, fluid condition and project documentation.

Non Return Valve PN 10/16

Non Return Valve PN 10/16 is listed in the check valve product range for non-return flow service.

This model should be reviewed based on the required installation condition, flow direction and project requirements.

Function

The main purpose of a check valve is to allow flow in one direction and prevent reverse flow.

In systems where reverse flow can affect operation, check valves are used as part of the pipeline design. Selection depends on the valve type, line condition and required non-return function.

Applications

Check valves in this category are used in applications such as:

• Water systems
• Wastewater systems
• Drinking water lines
• Agricultural irrigation systems
• Industrial installations
• Constructional installations
• Pumping stations
• Non-corrosive liquid lines

Selection Factors

Check valve selection should be based on the required valve type, pressure class, nominal size, flow direction, installation condition, fluid type and whether the system requires spring-assisted closing or another non-return configuration.

For pumping stations and systems where water hammer is a concern, the check valve type should be reviewed carefully according to the product documentation and project requirements.
