Model L Safesite Sight Flow Indicator

Description:

The Model L Safesite is developed to satisfy the need for pressure requirements from full vacuum to 100 psi while still providing the safety of PresSure Products higher-pressure units. This unit is an in-line (See- Thru) type that is used in existing or new piping to observe material flow through a line. It employs standard 150 psi ANSI B16.5 (2" to 8") flange ends to specified face-to-face dimensions. Model L Safesites can be supplied with indicators such as drip tubes, rotors or flappers, and rated for temperatures up to 450ºF. The unit can be provided with Silicone, Viton®, Teflon® or EPDM seals. Different materials of construction are available to meet your process needs, and other connections are available upon request including stub-end with lap joint flanges, butt-weld, threaded or sanitary. Units can be adapted to meet smaller or larger-size flange connections if necessary.
