Product overview
Black Lever Wiper and Slim Barrel Lamp Assembly
This variant is a circular union-closure vessel sight port fitted with a black contoured lever handle at the center of the lens and a slim metallic barrel lamp on the perimeter bracket. Front and rear gallery views show the central wiper shaft passing through the viewing glass to hold a radial blade against the vessel-side surface, allowing operators to wipe away condensation or film while illuminating the vessel interior.
Comparison with Metal-Crank Variant
Compared with the bent-metal-crank union sight glass version, this unit replaces the bent metallic crank arm and tall wireless lamp with a low-profile black lever handle and a narrower cylindrical lamp housing. The weld-in base neck and slotted union retaining ring are manufactured in SS304 or SS316L stainless steel.
Thermal Scope and Sealing Materials
The series specification specifies a temperature range of -10°C to 150°C for the base viewing port and -10°C to 80°C when equipped with the union lighting unit. The retained series schedule lists Silicone, EPDM, Viton, and NBR seal options along with DN150 and multi-standard (SMS, DIN, 3A, IDF, RJT, BS, ISO) series declarations.
Selection and Procurement Checks
Because this series specification does not include a dedicated dimensional drawing for the lever-wiper and slim-lamp envelope, buyers should confirm the nominal weld-neck diameter, overall protrusion height, wiper blade elastomer, and lamp power/switching details prior to vessel nozzle fabrication.
