PTFE Lined Diaphragm Valve

PTFE Lined Diaphragm Valve Manufacturer: FlowBiz Exports

The FlowBiz Lined Diaphragm Valve is specifically engineered for services involving highly corrosive acids, alkalis, and slurry-based media. By combining the structural strength of a cast body with a thick FEP or PFA lining, we provide a hermetically sealed flow control solution that eliminates metallic contact with the process fluid.

Rigorous Testing & Quality Assurance

To guarantee 100% safety in hazardous lines, every valve undergoes a comprehensive three-stage inspection:

  • Hydrostatic Test: $11\text{ kg/cm}^2$ to Full Vacuum (as per BS/API standards).
  • Pneumatic Test: $7\text{ kg/cm}^2$ for air-tight integrity.
  • Spark Test: 15 KVA DC to verify that the lining is free from pinholes or microscopic defects.

Key Features & Advantages

  • Exceptional Corrosion Resistance: The FEP/PFA lining protects the body against concentrated acids like Sulfuric ($H_2SO_4$) and Hydrochloric ($HCl$).
  • Leak-Free Stem Sealing: The diaphragm acts as a static seal, isolating the valve's internal working parts (stem and bonnet) from the process media.
  • Zero Contamination: Ideal for high-purity processes where fluid contact with metal must be avoided.
  • Bidirectional Flow: Designed to handle flow and provide bubble-tight shut-off in both directions.
  • Longer Service Life: High-grade PTFE backed by resilient Neoprene rubber ensures the diaphragm can withstand high-cycle operations without fatigue.
