1 NELES R SERIES V-PORT SEGMENT VLVE Metso's Neles V-port valve in the R-series is primarily intended as a control valve, but it can also be used for shut-off service. The R-series V-port segment valve is a good general control valve for most pulp and paper process applications. The valve can be fitted with an aerodynamic noise- and liquid cavitation-reducing (for example, steam and gas applications) Q-Trim segment. low capacity segment is available for the DN25 valve. FETURES Single-piece valve body R-series valves have single-piece bodies, which prevents leaks caused by separate flanges or locking rings. Durable metal seat The seat of the R-series V-port segment valve is firm and uniquely durable. The seat is designed in such a way that its sealing surface is not located directly in the flow stream. This gives the seat an extended service life. The working principle is a pressure-aided seat which enables good sealing properties at a low pressure difference. The seat is located inside the valve, which prevents forces from the pipe system influencing the sealing effect. PTFE seat The R-series V-port segment valve is also available with a soft seat. This is primarily intended for applications where a hard chromium plated segment is unsuitable, e.g. for acids and acidic liquids. This structure contains an X-treme seat, fitted in a body made of stainless steel. Bearings The bearings are located in the valve body, away from the flow stream, with a large bearing surface, offering a low bearing pressure and a long service life. Q-Trim Most pulp and paper mills have maximum noise levels for control valves. These limits are easily exceeded, especially for gas and steam applications, when using standard valves. High pressure drops, which occur during control of water and liquid flows, generate cavitation which may cause damage to the pipe system. The solution to these applications is the Q-Trim design. Impurities will not block the valve because of the selfcleaning design. The design can be used for media such as impure steam, black liquor, and even 3.5 % pulp. Low capacity Four different low capacity C v trims are available for the DN25 valve. These enable high accuracy control of small flows. Typical applications are, for example, dyes and other additives on a paper machine. Smooth action Because of the double bearing, the pre-tightened spring-loaded gland packing, and the low seat friction, the torque requirement of the R-series V-port segment valve is low. For this reason the size of actuator required is small. s a consequence, the control valve package combines low overall costs with good control performance. 1/2014
