SERIES 855 INLINE THROTTLING VALVE, PN16
The Series 855 In-Line Flow Throttling Valve controls flow using the principle of throttling across multiple tapered ports which are positioned around the valve liner. The port shape and arrangement can be designed specifically for each application to provide optimum valve performance and flow control characteristics.

Features

• Cylindrical Sleeve for hydraulic balance
• Vertical motion suitable good modulation capabilities
• Fine screw thread for slow speed operation and fine adjustment
• Annular gap between sleeve and liner ensuring minimum wear and low operating
