SEGMENT VALVE, RA WAFER AND RB FLANGED

Transcription

1 SEGMENT LE, R WFER ND RB FLNGED The segment 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 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 cavitationreducing (for example, steam and gas applications) Q-Trim segment. low capacity segment is available for the 25 valve. FETURES Single-piece valve body Both wafer and flanged R-series valves have singlepiece bodies, which prevents leaks caused by separate flanges or locking rings. Durable metal seat The seat of the R-series 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 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 a carbon filled PTFE seat, which is fitted in a body made of stainless steel. Bearings The bearings are located in the valve body, away from the flow stream: the bearing surface is large, which offers a low bearing pressure and a long service life. 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 segment valve is low. For this reason the size of actuator required is small. s a consequence, the result is a control valve package which combines low overall costs with good control performance. 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. igh pressure drop rations, 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 self-cleaning 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 v trims are available for the 25 valve. These enable high accuracy control of small flows. Typical applications are, for example, dyes and other additives on a paper machine. 3 R 21EN Issue 3/2004

Pressure and tightness testing of the valve Every valve manufactured by Metso utomation is subjected to a body pressure test and a trim tightness test. The test pressure of an R-series body is 1.5 x the maximum operating pressure. The pressure of the tightness test is 1.1 x the maximum operating pressure. The testing medium is water.
