Non-return check valve Greentek 120 mm model 00SP0448000

Greentek non-return check valve 120 mm model 00SP0448000 prevents reverse flow in piping systems by allowing fluid to pass in one direction only. It is intended for installation in drainage, wastewater and general plumbing lines with a 120 mm connection diameter and is suitable for residential and light commercial applications.

Advantages

The valve provides reliable unidirectional flow to protect pumps and connected equipment from backflow, which helps reduce the need for corrective maintenance. Its 120 mm connection size matches standard drainage and wastewater pipes, enabling straightforward installation and integration into existing plumbing systems.

Suitable for

• Domestic drainage and wastewater systems
• Light commercial plumbing installations
• Pump discharge lines requiring backflow prevention
• Stormwater and sewage pipelines with 120 mm connection diameter

Key specifications

• Connection diameter: 120 mm
• Function: non-return (check) valve for unidirectional flow
• Intended media: drainage and wastewater
• Typical installation: inline within piping systems

How to use

Install the check valve inline in the pipeline so that the flow direction marked on the body matches the intended flow. Ensure pipe ends are clean and properly aligned before connecting to the 120 mm sockets or couplings. Verify seals and connections after installation and test the system under normal operating conditions to confirm correct operation and absence of leaks.

Usage recommendations

For reliable performance, avoid exposure to solids or abrasive materials beyond typical wastewater content and perform periodic inspections to ensure the valve moves freely and seals correctly. Follow local plumbing codes and manufacturer installation guidelines when integrating the valve into existing systems.
