Shangyi 21000 Series Pneumatic Single-Seat Control Valve Technical Data and Selection Guide
Katup Kontrol Pneumatik Single-Seat Shangyi Seri 21000 is supplied by SANTAN for industrial process control, pipeline instrumentation and maintenance replacement projects.
Ringkasan Produk
The Shangyi 21000 series pneumatic single-seat control valve is used for modulating liquid, gas and steam service where accurate throttling and dependable shutoff are required.
Shangyi Product-Family Information
The official Shangyi valve catalogue identifies the 21000 series as a pneumatic single-seat valve family. Valve sizing and trim selection must be based on process data rather than nominal pipe size.
