While all our fluoropolymer valves offer exceptional chemical resistance, selecting the right material is key to maximizing performance and service life in your specific application.
The industry standard for corrosion resistance. Virgin PTFE provides a balance of performance and cost-effectiveness for a vast range of applications.
Best For: General to highly corrosive chemical services at moderate pressures and temperatures.
Key Trait: Unmatched chemical inertness.
Limitation: Susceptible to "cold flow" (deformation) under high mechanical load.
Reinforced PTFE (typically with 15% glass fiber or carbon) is engineered to overcome the mechanical limitations of virgin PTFE.
Best For: Higher pressure and temperature applications, or services with frequent cycling.
Key Trait: Significantly improved resistance to cold flow and deformation.
Limitation: Fillers may slightly reduce resistance to certain extreme chemicals (e.g., glass is not for Hydrofluoric Acid).
Perfluoroalkoxy is a premium, melt-processible fluoropolymer that combines the benefits of PTFE with enhanced mechanical properties.
Best For: High-purity (semiconductor, pharma), high-temperature, or vacuum services.
Key Trait: Higher mechanical strength and temperature rating (up to 260°C) than PTFE. Very smooth, non-porous surface.
Limitation: Higher material cost.
PTFE (Polytetrafluoroethylene) liners offer a unique combination of properties that make them the superior choice for demanding applications. PTFE is widely known by the brand name Teflon™, a registered trademark of The Chemours Company. We can supply valves with genuine Teflon™ materials upon request.
PTFE is virtually immune to all chemicals, including strong acids, bases, solvents, and chlorides, preventing liner degradation and ensuring long service life.
The smooth, non-porous surface of PTFE prevents media buildup and contamination, making it ideal for food & beverage, pharmaceutical, and semiconductor applications.
PTFE has one of the lowest coefficients of friction of any solid, reducing operating torque. This allows for smaller, more cost-effective actuators and smoother operation.
PTFE lined valves can handle a broad spectrum of temperatures, typically from -29°C to 200°C (-20°F to 400°F), making them suitable for both cold service and hot chemical processes.
We are not just a supplier; we are your vertically integrated manufacturing partner. From casting to assembly, we control every step to deliver valves that meet the highest international standards for performance and reliability.
ISO9001-2008, BV, and CE certified. We provide complete test reports for material, heat treatment, and mechanical performance with every shipment.
From raw casting and precision machining to final assembly, we control the entire production line. This ensures consistent quality and faster lead times.
Free Samples. Compare our valve quality against any other brand before you purchase. Experience the JRVAL difference firsthand.
With over 2,000 sets of independent machining tooling, we can deliver both standardized and fully customized valve solutions for any application.
