Overview
The pneumatic sleeve regulating valve adopts a separated sleeve, a large-area guide structure, a pressure balance sealing ring, a high-performance non-metallic sealing ring, and has good dynamic stability. High control accuracy. Large pressure difference is allowed. It has the characteristics of small operating force and large circulation capacity. Suitable for normal temperature working conditions. Fluid control under large pressure difference and alternating stress.
