They are reasonably priced and are therefore some of the most widely used shut-off, control and throttling valves.• PFA/PTFE lined diaphragm valves are used for corrosive, pure and ultrapure liquids, gases and vapours in chemical, pharmaceutical, food and industrial processes.• Hermetically tight• FDA-compliant, wetted PFA and PTFE materials• Soft-sealing, gas-tight• Operating pressures from -30 to +150 °C• Rated pressure: PN 16 (up to DN 50 or 2“), PN 10 (DN 80 or 3“ and larger); for operating pressure and vacuum, see page 4.• Solids-free or slightly solids-laden media.Product features• Leakage rate in the seat: DIN EN 12266-1, leakage rate A: gas-tight, 0 bubbles• Face-to-face optionally - Type MV: to ISO 5752-R.1 (DIN 3202 F1), flanges ISO 7005-2, on request drilled to ASME Cl. 150, BS or JIS - Type MVM: to MSS SP-88, flanges to ASME B16.5 Cl. 150• Anti-adhesive wetted PFA/PTFE surfaces • Clean-room applications: stainless steel version with PFA lining for type MV DN 15+20• Top-entry design: maintenance possible without dismantling• Identification of the valve to DIN EN 19, ASME B16.34Type codes• Manual actuation MV/..., MVM/...• Remote actuation MVP/..., MVMP/...Lining• PFA .../F• antistatic PFA-L .../F-LRemote actuation• With pneumatic actuators - of column/yoke-style design (e.g. Samson, Valtek, Fisher, Arca etc.) or - of compact design, details on request• Electric actuators• Accessories, e.g. positioners and limit switchesMVP with yoke-style actuatorMVP with compact actuator3b Diaphragm made of modified PTFEThe quality and functionality of the diaphragm are crucial for the reliability and durability of the valve. Top priority is given to these aspects in Richter diaphragm valves. • Greater fatigue strength under reversed bending stresses and dimensional stability even after many switching cycles and at fluctuating temperatures• Higher density and lower permeability• All-round sealing bead limits the medium chamber exactly and thus prevents residues in sealing gaps which are difficult to flush• Thick-walled, more per meation-resistant than diaphragms made of laminated PTFE• Enclosed all-round by valve bon- net, prevents the flow of PTFE• Optionally three layers with PVDF intermediate diaphragm for highly permeating mediac Floating tube nut diaphragm attachment with stainless steel compressor• ensures uniform distribution of the stem closing force and • therefore prevents localised loading and the sintered diaphragm bolt from being pushed throughSafety stuffing box optional• for hazardous or environmentally critical media• can be adjusted from outside by hand• acts independently• on request with monitor connectionpacking nutTemperature in °CVacuum (mbar)Gauge pressure (bar)Vacuum (psia)Gauge pressure (psig)Temperature in °F0200400600800-40 -20 0 20 40 60 80 100 120 140 1601000012936150246816-40 -5 30 70 105 140 175 210 250 285 3201012142352051750115853060145A395, 1.4308DN 150 (6”, 8”)DN 100 (4”)DN 80 (3”)DN 15, 20, 25, 40 (1”, 11/2”)DN 200 (8”) on requestLining PFA/PTFEDN 15, 20DN 80, 100 (3”, 4”)EN-JS1049 DN 25, 40, 50 (1”, 11/2”, 2”)EN-JS1049 DN 150 (6”, 8”)A395DN 50 (2”)Pressure/temperature rangeEDPM diaphragm support mod.-PTFE diaphragm5710294111683For low-temperature applications please observe the local regulations DN bar (psi) 1 2 3 4 5 6 8 10 12 14 16 mm Zoll (14.5) (29) (43.5) (58) (72.5) (87) (116) (145) (174) (203) (232)15 1/2” 976 1.040 1.105 1.181 1.246 1.311 1.441 1.582 1.712 1.842 1.97220 3/4” 1.370 1.473 1.572 1.676 1.779 1.880 2.085 2.287 2.494 2.697 2.90425 1” 1.370 1.473 1.572 1.676 1.779 1.880 2.085 2.287 2.494 2.697 2.90440 11/2” 1.598 1.863 2.133 2.398 2.663 2.931 3.463 3.997 4.529 5.073 5.61650 2” 1.598 1.863 2.133 2.398 2.663 2.931 3.463 3.997 4.529 5.073 5.61680 3” 2.904 3.645 4.383 5.120 5.861 6.598 8.077 9.556100 4” 5.019 6.105 7.190 8.273 9.360 10.446 12.616 14.786150 6” 6.665 8.744 10.825 12.907 14.985 17.067200 8” on requestRequired seating thrust in N for actuator sizing(p1 is stated at p2 = 0 bar)Other nominal sizes on request.
