Q367F Welded Ball Valve
Fully Welded Body – Leak-Free Integrity
Integral welded body design with no flange or bolted joints, fundamentally eliminates leakage risks caused by aging gaskets or loose bolts.
Superior Sealing - Designed for Gas Pipeline Safety
Engineered for natural gas networks with high-performance sealing to prevent gas leakage and ensure safe, energy-efficient operations.
Pressure & Corrosion Resistance - For Harsh Environments
Built to withstand high pressure, underground burial, and corrosive conditions, ideal for urban and long-distance transmission lines.
Full Bore Design - Minimal Pressure Drop
Full bore passage ensures unimpeded flow with minimal pressure loss, maximizing pipeline transmission capacity.
Low Maintenance - Built for Longevity
Simplified construction reduces failure points and maintenance, ideal for long-term buried or remote installations in gas systems.

- Application Conditions
Municipal Water Supply & Drainage Systems
Soft-seal gate valves are widely used in municipal water supply networks, stormwater drainage and sewage treatment plant pipelines because of their excellent sealing performance and minimal flow resistance.
Buried Pipelines & Underground Infrastructure
In buried pipelines and underground infrastructure—such as rural water networks, sewage mains and sub-surface utilities—soft-seal gate valves provide reliable shut-off and sealing under constrained installation conditions.
Low-to-Moderate Temperature & Pressure Systems
Suitable for systems where the fluid temperature is typically below ~80 °C and pressure is moderate (e.g., PN10–PN25), soft-seal gate valves excel in tight shut-off and minimal leakage.
Clean or Slightly Particulate-Bearing Fluids
Due to elastic sealing materials and groove-free seat design, these valves are well suited for clean water, municipal sewage or general service pipelines—not ideal for heavy solids, high temperature or strongly corrosive fluids.
Heating, HVAC, Fire-Water Systems
In heating systems, HVAC loops or fire-protection mains, soft-seal gate valves serve as reliable cut-off valves where low opening torque and leak-tight shut-off are valued.

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.

UZBEKISTAN Chemical Project
- North South Interconnector Pipeline
Customer/Owner: FARG’ONAAZOT chemical factory
- Working conditions/Challenges:
Farg’onaazot, the second largest chemical factory in UZ.Their oil and gas pipelines require a large number of high-pressure valves. Previously, the valves often malfunctioned, causing equipment to shut down, and the product lifespan was less than one year.
- The type of equipment adopted:
We have been cooperating since 2023, providing them with high-quality high-pressure valves, including high-pressure ball valves, fluorine-lined valves and other products.
Key indicators: After our products were installed in the pipeline, they operated smoothly. In 2024, we conducted an after-sales follow-up visit to the customer’s factory, and the customer company expressed high praise for our products.
