- Application Conditions
Water Supply & Wastewater Pipelines
The valve is used to prevent reverse flow and protect pump stations and pipeline equipment in water supply and wastewater collection systems.
Check at Pump Discharge & Circulation Systems
Installed at pump discharges or in circulation systems to ensure unidirectional flow and protect equipment from backflow.
Medium Temperature/Pressure Systems for Water, Steam, Oil
Suitable for systems with moderate temperature and pressure—such as water, steam or light oil transport.
Horizontal Installation in Space-Constrained Piping
Designed for horizontal pipeline installation—ideal for environments where space is limited.
Environments with Light Solids or Low Erosion Media
Reliable for environments with light suspended particles or low erosion media—such as domestic wastewater or circulation systems.

Testing Process
From raw materials to finished products, NORITE maintains 100% testing coverage, ensuring that every valve and pump you receive is built to last — safe, stable, and globally certified.
Pressure Testing
Each valve undergoes rigorous pressure and hydrostatic testing prior to shipment to verify body strength, sealing integrity, and pressure stability—ensuring zero leakage and long-term reliability in field operation.
Torque and Functional Testing
Confirming operating performance and precision.
Cycle Life Testing
Simulating long-term use under real working conditions.
Coating & Corrosion Resistance Testing
Validating surface protection and durability.
Dimensional & Material Analysis
Using spectrometers and coordinate measuring machines (CMM) for accuracy.
Traceability - Unique product code
Each product leaving our factory is accompanied by a full inspection report and a unique serial number, enabling full traceability and lifetime quality tracking.

Tibidabo Pump Station
- Barcelona, Spain
Customer/Owner: Municipal pumping station in Barcelona, , Spain
- Working conditions/Challenges:
The pumping station is equipped with Swing Check Valve. Significant pressure shock was detected during the pump stop event, and the “valve closing impact” phenomenon was severe.
- The type of equipment adopted:
We provided a complete set of products including check valves, gate valves and joints for the upgrade of this pumping station system.
Key indicators: In water supply, sewage treatment and fire protection systems, Swing Check Valve are important components for preventing backflow and protecting pumping stations
