Product Description

U-ideal manufacture full range of sight glass flow indicator-Sight glasses, such as Floating ball Sight Glass,
rotating wheel sight glass, flapper sight glass, agitating ball sight glass,wipper sight glass
Installation size is small, and the drive torque is small, easy operation, quickly, and at the same time also has a good flow regulating function and close the seal characteristics, sight glasses in large and medium size, use of low pressure area, it is the dominant form of sight glasses. Lens is divided into two broad categories: Valve pipe sight glasses lens with the device

Sight glasses are one of the main industrial pipe fittings. They are be used to observe pipe liquid, gas, steam etc. reaction conditions. Monitor production and to keep safe process.
