The axial flow check valve (also known as a nozzle check valve or axial non-return valve) is designed to allow fluid to flow in one direction only. Unlike swing check valves, the disc moves along the flow axis, resulting in faster response, lower pressure drop, and reduced water hammer effects. This design is preferred in high-velocity pipelines and critical process systems where reliability is non-negotiable.
KONTE axial check valves are manufactured under strict quality control standards, including 100% pressure testing and full inspection records kept for over 10 years.
▶Castings offer excellent mechanical strength, capable of withstanding high pressure and impact loads over long periods.
▶Precision molds ensure consistent dimensions, allowing tight assembly tolerances and reliable valve performance.
▶Materials like WCB, CF8, CF8M, and other stainless or alloy steels provide good resistance to corrosion in various media.
▶Casting enables the production of complex internal and external structures that are difficult or impossible to machine.
▶Available in a wide range of materials (e.g., carbon steel, stainless steel, alloy steel), allowing customization for specific applications.
▶Casting is ideal for mass production, reducing machining time and overall production cost.
▶Cast components can endure high temperatures and abrasive flow, making them suitable for harsh environments.
▶Designs can include customer-specific logos, flow markings, and custom ports or shapes.
▶Valve castings often conform to standards like ASTM, ASME, ISO, DIN, or EN, ensuring compatibility and performance.
▶Optimized wall thickness and structure design provide good resistance to internal pressure surges.

Q1: What is the maximum pressure rating for KONTE axial flow check valves?
Standard models are rated to PN16 (Class 150). Higher pressure ratings (PN25, PN40, Class 300/600) are available on request. Please share your working conditions for a tailored recommendation.
Q2: What materials are available?
Standard options include WCB (carbon steel), CF8 (316 stainless steel), CF8M (316L stainless steel), duplex stainless, and alloy steel. Material selection depends on media, temperature, and pressure requirements.
Q3: Can you supply with pneumatic actuators?
Yes. All models in the Q47–16C series are available with pneumatic actuators. Electric actuators and manual overrides are also configurable.
Q4: Do you support OEM and private label orders?
Yes. KONTE has 10+ years of ODM experience. We accept custom valve designs, logos, packaging, and documentation for distributors and brand owners worldwide.
