Absolutely. We offer OEM/ODM customization including NAMUR and ISO 5211 mounting patterns, top-mounted solenoid valves (ASCO, Norgren, Festo), limit switch boxes, positioners (Fischer, Siemens, Rotork), and specialty coatings for corrosive environments. Just share your datasheet and we'll match it.

Every assembly undergoes hydrostatic testing (1.5x rated pressure), pneumatic seat leakage test (bubble-tight), and full stroke cycle test with actuator. We also offer third-party inspection by SGS or Bureau Veritas at your request. Our ISO 9001:2015 system covers all production stages.

Based on customer feedback across 40+ plants, our pneumatic ball valve delivers comparable cycle life and leakage performance at 40–55% lower upfront cost. Over a 5-year TCO horizon including maintenance and spare parts, customers report an average savings of 37%. We can prepare a side-by-side comparison for your specific application.
