H76X Wafer Check Valve
Compact Design for Space Efficiency
The waferstyle check valve is installed between two flanges, featuring a slim profile and light weight—ideal for piping systems with limited space.
Reliable Back-Flow Prevention & System Protection
Designed with a swinging or dual‐plate disc that automatically closes under reverse flow, effectively preventing back-flow or cross-contamination.
Low Pressure Drop & High Flow Capacity
The wafer check valve offers minimal obstruction when open, allowing high flow capacity and reducing pressure loss across the valve.
Easy Installation & Multi-Orientation Use
Supports both horizontal and vertical installation, with simple flange sandwiching—ideal for both new systems and retrofits.
Wide Material & Specification Options for Diverse Conditions
Available in carbon steel, stainless steel, ductile iron bodies, with seal choices such as EPDM, Viton, PTFE—suitable for water, steam, gas, corrosive media and a wide range of sizes.

- 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.
