D341X Flanged Butterfly Valve
Robust Construction with Reliable Sealing
Ductile iron or carbon steel body with high-elastic EPDM/PTFE seat ensures zero leakage in both flow directions.
Versatile for Industrial and Municipal Applications
Standard flange ends (PN10/16 or ANSI Class150) allow easy integration into water plants, pumping stations, buildings, and process pipelines.
High Flow Capacity with Low Pressure Loss
Full bore design and precision-machined disc reduce flow resistance and enhance system efficiency, especially for large diameter pipelines.
Easy Operation with Multiple Actuation Options
Available with lever, gearbox, electric, or pneumatic actuators to suit various automation needs.
Excellent Corrosion Protection for Harsh Environments
Fusion bonded epoxy coating ≥250μm inside and outside; WRAS-approved coating and rubber available for long-term corrosion resistance and potable water safety.

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.
