The ZIGHT sight glasses made of STAINLESS STEEL or BRASS allow a view of the level in a tank.
The valves are forged in a single piece, which guarantees excellent resistance to pressure and the most adverse conditions.
The equipment is designed to work in different tanks, the standard connection is 1/2 ”NPT or 3/4” NPT; the design pressure of the level valves is 250 PSI. They can also be manufactured in 1 ”NPT and 1-1 / 2” NPT.
Depending on the pressure to work and temperature to work, the type of level tube will be recommended (standard wall, high-pressure wall, or extra-reinforced wall.
Similarly, appropriate gaskets may be recommended, these can be made of Viton, EPDM or Teflon.
The equipment can have protective rods, these can be made of 304 stainless steel threaded at the ends; or in pressed aluminum
