Richter and -Way Sight Glasses PSG, TSG, SGS, SR Corrosion-resistant PFA and PTFE lining Indication of flow even at very low flow rates Optionally with integrated chec valve
Richter and -way sight glasses Observation of flow, filling level, condition, colour and gas contents of liquids in pipes and vessels and near pumps. Richter sight glasses are designed for media where stainless steel and plastics such as PVC, PP, PVDF etc. are not adequately corrosion-resistant as alternative to valves made of special metals (Hastelloy, Monel, tantalum etc.) and to glass-lined valves for pure and slightly solids-laden media for metal-reactive media, e.g. H O for pure media where good cleaning possibilities and anti-adhesive surfaces are important. Operating range: Depending on design and material -60 to 80 C (-7 to 60 F), SGS max. 0 C (00 F) vacuum to 6 bar ( psi), SGS max. 6 bar (87 psi) horizontal to vertical installation Product features PSG + TSG: very sturdy design, ductile cast iron with thicwalled lining Face-to-face lengths to DIN EN 8-, basic series (ISO 7 basic series ), SGS series additionally with face-to-face lengths up to,000 mm. Flange connecting dimensions: DIN EN 09-, shape B (ISO 700-, shape B) on request drilled to ASME (ANSI) Cl. 0 Various other options, see page Type codes for sight glasses -way design PSG/... -way design TSG/... -way cylindrical sight glass SGS/... ining: Perfluoroaloxy (PFA) and.../f Polytetrafluoroethylene (PTFE) Highly permeation-resistant PFA-P.../F-P Antistatic PFA-.../F- Other product features Pressure-bearing shell made of ductile cast iron EN-JS 09 (ASTM A9) absorbs system and pipe forces Thic-walled lining made of virgin, pure PFA and PTFE Suitable for almost all media including corrosive, pure, hot and highly permeating media Vacuum-resistant anchoring Conductive and highly permeationresistant linings optional Universal use for a wide variety of media, also in multi-purpose and test plants Glass panes and cylinders Borosilicate glass to DIN 7080 arge free field of vision PSG + TSG: sight glass panes and covers to DIN 7-, screwed individually to body SGS series: cylindrical glass with all-round vision, optionally cavity-free for high-purity media Integrated drip lip with DN - ( /- ): also indicates very low flow rates External corrosion protection Epoxy coating, nuts and bolts of stainless steel. Identification to DIN EN 9, ANSI B6.

D d DN integrated drip lip as flow indicator for very low flow rates Standard design Optional cavity-free design for pure and high-purity fluids e.g. in pharmaceutical and fine chemical applications On the wetted side the cylindrical glass evenly flushes with the valve lining. This prevents from residues and optimises cleanability. Design cavity-free goes without drip lip. Design cavity-free
