As a leading China air valve manufacturer with over 16 years of engineering excellence, FTJ Valves designs and manufactures heavy-duty automatic air release valves, air/vacuum valves, and combination air valves engineered to protect water pipelines from air binding, pressure surges, and vacuum collapse.
Trapped air pockets can severely restrict flow capacity, increase energy consumption, and cause catastrophic water hammer in municipal and industrial fluid systems. Our china air valve solutions automatically vent accumulated air during operation and rapidly exhaust or admit large volumes of air during pipeline filling and draining. Built under strict ISO 9001 systems and conforming to AWWA C512, EN 1074-4, and DIN standards, FTJ air valves deliver long-term, leak-free pipeline stability.
Key Features of FTJ Industrial Air Valves
Triple-Function Operation: Combines large-orifice air release (filling), large-orifice vacuum breaking (draining), and small-orifice air venting under pressurized line operation.
Ductile Iron & Stainless Steel Construction: High-strength Ductile Iron (GGG50) or WCB body options coated with fusion-bonded epoxy (FBE) for superior corrosion resistance in raw water, potable water, and wastewater applications.
Anti-Slam Mechanism: Advanced internal float and baffle design prevents premature valve closure caused by high-velocity air discharge.
100% Pressure Tested: Every china air valve undergoes rigorous shell and seat hydro-testing prior to dispatch to guarantee zero leakage and precise seal activation.
Full Certification & Traceability: Supplied with complete Material Test Certificates (EN 10204 3.1), WRAS-compliant elastomeric seals, and pressure test reports.
