The control medium must be free from any solid particles and condensed water (Important in the event of frost!). 1) From DN 100 we recommend installing a gearbox for operating pressures > 10 bar. 2) The temperatures indicated are for orientation only; they are not valid for all operating conditions. 3) Double piston SISTO-16 3

4 Body materials Overview of available materials Material Material number Temperature limit 2) EN-GJL C to +160 C Two-piece diaphragm made of TFM/EPDM; temperature limit +160 C Lead-sealable cap (prevents unauthorised actuation) Stem extension Certification to customer specification Design details Diaphragm valve design Soft-seated shut-off valve in straight-way pattern Rising handwheel Shut-off and sealing to atmosphere by spiral-supported, completely enclosed diaphragm Position indicator with integrated stem protection Manufactured and tested to EN Marked in accordance with DIN EN 19 (ISO 5209) The valves satisfy the safety requirements of Annex I of the European Pressure Equipment Directive 97/23/EC (PED) for fluids in Groups 1 and 2. Valves without electrical components do not have a potential internal source of ignition and can be used in potentially explosive atmospheres, Group II, category 2 (zones 1+21) and category 3 (zones 2+22) to ATEX 94/9/EC. Components such as electric actuators, position switches, block terminals, solenoid valves etc. may in certain circumstances be covered by Article 1 of the EC Directive 94/9/EC. They must be subjected to a conformity assessment procedure and separate evidence of compliance must be provided (e.g. EC declaration of conformity or manufacturer's declaration). The valves meet the requirements specified in TA-Luft (German Technical Guidelines on Air Quality Control, VDI 2440). Variants Actuator (electric or pneumatic) Limit switches Locking device Body lined with IIR (Butyl); temperature limit: +120 C Body lined with NRH (hard rubber); temperature limit: +100 Body coated with ECTFE (Halar); temperature limit +90 C Body coated with PA (Rilsan); temperature limit +90 C 4) Leakage detection hole and additional stem seal Diaphragm made of CSM; temperature limit +100 C Diaphragm made of EPDM; temperature limit +140 C Diaphragm made of EPDM/W270; temperature limit +90 C Diaphragm made of EPDM-V (vacuum); temperature limit +140 C Diaphragm made of IIR; temperature limit +120 Diaphragm made of NBR; temperature limit +90 Actuators SISTO-LAD diaphragm actuator Sliding stem sealed by O-rings Mechanical travel stop in the actuator for closed and open positions Manual override available as standard for spring-to-close design LAD-AZ actuator type: air-to-open/air-to-close LAD-ÖF actuator type: spring-to-open/air-to-close LAD-SF actuator type: air-to-open/spring-to-close SISTO-LAP piston actuator Double-acting piston, with piston rod extending from one end only, with or without spring Piston rod sealed by U-ring and scraper ring Piston with double cup seal and vulcanised metal disc Mechanical travel stop in the actuator for closed and open positions Flanges to DIN ISO 5210/DIN 3358 Pistons Ø 80 to Ø 300 = F10 Pistons Ø 250 to Ø 300 = F14 LAP-AZ actuator type: air-to-open/air-to-close LAP-ÖF actuator type: spring-to-open/air-to-close LAP-SF actuator type: air-to-open/spring-to-close Electric actuator Multi-turn actuator Linear actuator Product benefits Reliable sealing to atmosphere and absolutely tight shutoff The diaphragm provides absolutely tight shut-off as well as hermetic sealing to atmosphere and of all operating elements. Maximum service life and pressure limit Maximised diaphragm life and pressure limit thanks to completely enclosed, spiral-supported diaphragm. Excellent functional reliability Increased functional reliability of the diaphragm thanks to balanced diaphragm suspension. Excellent resistance to corrosion and abrasion High-quality linings offer reliability and a long service life. 4) Temperatures of +90 C for periods of up to one hour resulting from one-off incorrect system operation will not impair the valve's functioning. 4 SISTO-16

5 Smooth actuation The thrust bearing minimises the closing torques. Optimised long-term operation The stem protection integrated in the position indicator prevents ingress of contaminants. Fluid purity Valve hydraulics without dead volume ensure optimum conditions for high-purity fluids and protection against deposits. Fast checking of valve position The valve's position can be easily checked via a clear visual indicator, also visible from a distance. Reliable operation The stem and all internal operating elements are not in contact with the fluid.
