Frequently Asked Questions

Q1: What standards do your plastic butterfly valves comply with? Our valves are manufactured to meet DIN, ANSI, JIS, and BS standards, ensuring compatibility with international piping systems.

Q2: What is the maximum size available for the PVC butterfly valve? We specialize in large-size valves, with product sizes ranging from DN15mm (1/2") up to DN400mm (16").

Q3: Are these valves suitable for chemical applications? Yes, our valves are made from high-quality PVC-U, CPVC, and FRPP materials which are acid-proof and alkali-proof, making them ideal for industrial and chemical usage.

Q4: Can I install an electric or pneumatic actuator on these valves? Absolutely. We offer an "Integrated Structure" version with ISO5211 standard mounting holes, allowing for direct connection to actuators without needing an extra bracket.

Q5: Do you use recycled materials in production? No, we use 100% hygienic level PVC raw materials and virgin rubber (EPDM/FPM) to ensure mechanical performance and a long service life.

Q6: How do you ensure the sealing performance of each valve? Every single valve undergoes a 100% pressure test on each sealing link before packaging to ensure zero leakage.
