If the client produces such a connector on its own, please specify the diameter and the thickness of the pipe. The connection dimensions of the connector are cooled as per the PN-EN 1092- 1: 2010 norm for the (C) type of the flange. The sealing is standard for the (C/D) type flange connection. It is recommended to use an elastic spiral wound gasket made of the X6CrNiMoTi 17-12-2 ; (1.4571) material + GRAPHITE. Table 4. Dimensions of the gasket.

ORDERING (only piston desuperheaters): When ordering please state the marking of the drive as per the producer’s catalogue cards, the marking of the desuperheater and its operation parameters: the pressure and temperature of the flowing medium. Apart from the a/m data, the following information is stated on the rating plate of the desuperheater: - max working temperature [TS], - max. working pressure [PS] - test pressure [PT] - liquid group [2], - serial number and year of manufacturing. The assistance in selecting a desuperheater is granted by: the Marketing and Sales Department and the Technology Department. 134 Steam pipeline: DN / PN Revision: ST-1; SP-1/07/2014 Valid until the next revision.
DIAPHRAGM MULTI-SPRING PNEUMATIC ACTUATORS TYPE P/R APPLICATION AREA The multi-spring membrane pneumatic actuators of P/R type are applied for control operation of control valves and other positioning elements in industrial automatic systems. There are three following design options of the acutator: - direct action (air - ejects the stem) - type P, - reverse action (air – retracts the stem) - type R, - direct action, handwheel - type PN, - reverse action, handwheel - type RN FEATURES • completely reversible action, option to change spring range w/o extra parts, • actuator mounted on the columns, • wide range of the available forces, • linear relationship between rod displacement and control pressure as a result of using membranes with constant active area, • various ranges of spring pressures due to changeability of spring number and /or dislocation of distance fencers, • capability of the actuator o incorporate side-mounted handwheel,pneumatic or electro-pneumatic positioners, limit switches, air sets, three-way pneumatic solenoid valves, lockup valves, position transducers, • possibility to equip with accessories allowing to decrease or increase distortion time, • high strength of diaphragms, springs and packings, • small size and weight TECHNICAL PARAMETERS input signal range: 20...100 kPa; spring range marking: 1 40...200 kPa; 2 40...120 kPa 3 80...240 kPa; 4 60...140 kPa; 5 120...280 kPa 6 180...380 kPa 7 Number of springs: standard version: range 1, 3, 5 - 3 springs range 2, 4, 6 - 6 springs range 7 - 12 springs version TANDEM: range 1, 3, 5 - 6 springs range 2, 4, 6 - 12 springs range 7 - 24 springs - working temperature: - 40...+80°C - relative humidity: max. 98% 135
