It is designed for external mounting on a tank and reliably indicates the liquid level inside the container according to the principle of communicating vessels. Type 460 is available in freely selectable lengths and can optionally be supplied with threaded or flanged connections. If the center distance between the valve axes exceeds 1500 mm, the pipe is divided into several sections that are stably connected together using spacers. A stuffing box seal made of PTFE inside the valves ensures a secure seal. In case of contamination or damage, the valve liquid level indicator can be safely disconnected from the container and emptied at the connection points using the integrated shut-off valves. Due to the sensitive glass tube, type 460 is delivered unassembled. When assembling – especially with flange connections – care must be taken to ensure that the connections are precisely aligned and not twisted against each other to ensure stress-free installation of the glass tube. To protect the glass tube from mechanical impacts during operation, an impact protection tube made of Plexiglas® is optionally available.

The indicator features a square frame with two end face Welding ends of Ø 20 mm. The fitting is equipped with a sight glass made of high-quality borosilicate glass according to DIN 7081. This is securely encased between gaskets and tightly screwed to ensure permanent tightness and high pressure resistance. Standardly, the sight glass type 410 is made of stainless steel 1.4571 (316Ti) – a material characterized by high corrosion resistance and durability. On request, the design is also available in many other materials, suitable for specific requirements and applications. The sealing of the fitting is done with flat gaskets tailored to your needs from an extensive range of materials. This offers not only the commonly used fiber gaskets but also more sophisticated materials such as PTFE (Teflon®), novaphit® MST-XP, and KlingerSil® C4400. Important notice: Reflective sight glasses cannot be combined with mica discs and coatings, as the protective mica layer prevents the necessary light refraction for reflection.

Glass in the production process is subjected to a polishing and toughening. This results in products characterized by high mechanical strength and high resistance to alkalis, acids and condensates. In the production process is conducted constant and precise control of transparency and the dimensions of manufactured glass. Reflex gauge glasses  are used to read the liquid level directly or with the use of CCTV (industrial television). In this type of glass on the chamber side (medium side) are imprinted longitudinal grooves (3 or 4), which walls are angled to each other at an angle of 90˚. Squeezing process causes the formation of grooves. On the surface of the grooves creates extremely smooth and hard glass layer, very resistant to the environment. With the grooving increases the angle of refraction which makes the visibility of the liquid level is much better than when using smooth glass. For reflective glass does not apply mica shields. Reflex glasses may be used in pressure up to 35 bar. In this area are sufficiently resistant to the environment. The reading is clear and contrast. In the case of factors other than steam reflex glasses may be used up to 400 bar or 400˚C. Depending on the width and thickness there are three basic types of transparent level gauge glasses: type A - width 30 mm, thickness 17 mm type B - width 34 mm, thickness 17 mm type H - width 34 mm, thickness 22 mm In addition, the occasionally encountered also: Type C - width of 20 mm, thickness 12 mm Type D - width 25 mm, thickness 15 mm Reflex level gauge glasses are supplied in sets with gaskets or separately.
