Richter PFA/PTFE Shut-off and Control Butterfly Valves

Richter PFA/PTFE Shut-off and Control Butterfly Valves NK, NKS, NKL, NKS-C, NKL-C New: Sizes to 4 ( mm) Titanium, PE-UMW Body lining PTFE, TFM-PTFE, PTFE-antistatic, PE-UMW Disc/stem unit PFA, PFA-antistatic, SS, astelloy, Ti, special metals Clean Air Act Conformity

NK, NKS, NKL, NKS-C, NKL-C Richter wafer-style, lug-style and double-flange butterfly valves Fields of application Richter butterfly valves have proved successful in a wide variety of process plants. Shut-off, throttling and control of corrosive, hazardous and pure liquids, gases and vapours, e.g. - wet Cl gas and NaO in chlor-alkali electrolysis - large flows in the distribution and treatment of SO 4, Cl, NaO, NaOCl, chemical effluent etc. FDA-compliant, wetted materials for use in food processing, pharmacy and similar fields. Also suitable for free-flowing, low-abrasive bulk materials in the version with a metallic disc/stem unit. The compact butterfly valves are advantageous in confined spaces e.g. under vessels. Butterfly valves are economical valves: easy to install and dismantle, attractively priced, compact. Operating range -4 F to +4 F (-4 C to + C).15 psi to 145 psi vacuum (.1 mbar to bar vacuum) Product features Soft-sealing and gas-tight, both with lined and metallic disc/stem unit Leak-tight against the atmosphere in compliance with the German Clean Air Act (TA-Luft) Optional with safety stuffing box (series NK, NKS, NKL) Leakage rate in the seat to DIN EN 166, leakage rate A (formerly DIN 33 T3): gas-tight, bubbles Almost equal-percentage characteristics Face-to-face: ISO 575 series, API 69 Table 1, MSS SP-67 Table 3 Flanges (with lug-style and double-flange bodies) for connection to ISO 75- PN, ASME (ANSI) B16.5 Class 15, JIS R -K Anti-adhesive wetted surfaces thanks to PFA/PTFE Identification of the valves: DIN EN 19, ASME (ANSI) B16.34 Actuation: - hand lever, lockable - worm gear with handwheel - pneumatic/electric actuators Type code, wetted linings and available sizes see page Depending on the body version, the butterfly valves can be installed As a wafer-style valve ( sandwich-type ) with all three body versions or As a flange-mounted or dead-end butterfly valve with lug-style and double-flange body. a Single-piece disc/stem unit optionally fluoroplastic Lined with pure PFA for maximum corrosion resistance and a long service life. Very low friction values and torques during opening and closing due to the combination of a PFA disc/stem unit with a PTFE body Optionally antistatic PFA-L Disc/stem core made of highly torsionresistant Duplex stainless steel 1.4517/CD-4 MCu (18-4 /DN 45-: SS 1.4435/316L) Alternatively metallic Made of precision cast stainless steel - Polished sealing surfaces, therefore very low friction values - Polished disc surfaces on request Other materials on request, e.g. astelloy C, titanium b Thick-walled PTFE and TFM-PTFE lining of the valve body TFM-PTFE lining ( -16 /DN 5-4 with PFA-lined disc: PTFE as standard, optionally TFM-PTFE) Lining thickness.1-.15 (3-3.5 mm) igh permeation resistance Vacuum-proof Optionally antistatic PTFE-L, PE-UMW Wide sealing surfaces of body lining for reliable sealing even with mating flanges with large radii, e.g. glass-lined components c Permanently elastic seal in the valve opening by means of silicone insert under the PTFE body lining. Optionally FKM insert (e.g. Viton ) for use with chlorine gas for example

d Double-action, maintenancefree and self-adjusting top and bottom stem sealing, therefore reliable even with many switching cycles and fluctuating temperatures: - primary: body lining against disc/stem shoulder - secondary: O-ring FKM, optionally FFKM Compliant with the German Clean Air Act even in the standard version without safety stuffing box e Pressure-bearing body made of ductile cast iron EN-JS 49 ASTM A395 Absorbs system and pipe forces Centers the valve in the pipe Optionally body made of stainless steel or carbon-fibre/glass-fibrereinforced vinyl ester f Long valve neck permits optimal heat insulation without the installation of an elevated lever, additional stem extensions on request. g External corrosion protection Epoxy coating, nuts and bolts made of stainless steel h Centering to ISO 511 Chlorine electrolysis options Specially for use with wet chlorine gas: Elastic insert made of Viton instead of silicone Body lining made of particularly permeation-proof, modified TFM- PTFE instead of standard PTFE Body nuts and bolts made of steel, for example, instead of stainless steel Tantalum-coated ductile iron body 8 6 4 5 3 1 7 Wafer-style body NKS, NKS-C Lug-style body NKL, NKL-C Double-flange body NK 3
