ZTVK Fluid CONTROL Equipment conveys enterprise-grade butterfly valve double flange type arrangements designed for requesting mechanical applications. Our valves include progressed one-piece design that diminishes working torque by 30% whereas expanding benefit life past 50,000 cycles. Accessible in sizes from DN50-2000mm with working weights up to PN16, these valves bolster numerous materials counting SS304/SS316 with EPDM/NBR/PTFE fixing alternatives. With over 15 a long time of fabricating ability and ISO9001 certification, we keep up 2000+ standard units in stock for fast 3-7 day delivery.
You require solid stream control gear that performs reliably beneath weight. Our twofold spine plan gives predominant solidness and leak-tight execution in your basic applications.
Our valves consolidate a twofold unconventional setup with angled fixing innovation. This inventive approach diminishes wear and amplifies operational life essentially. The plan minimizes grinding amid operation, making valve cycling smoother and more reliable.
You'll appreciate the lightweight development without compromising quality. Each valve experiences thorough testing to guarantee it meets your requesting specifications.
We offer comprehensive material options to match your specific environment:
The disc materials include ductile iron, CF8, CF8M, and aluminum bronze options. You can select the combination that best suits your operating conditions.
Your operational requirements vary, so we provide multiple actuation options:
Reserved interfaces allow future upgrades without replacing the valve body. This butterfly valve double flange type design supports your evolving automation needs.
