Product Details

Combined Sight Glass and Check Valve

Spirax Sarco combined sight glass and check valve has been designed to observe discharges from steam traps. There is no need for a separate check valve as the condensate rises after the trap due to its position, thus simplifying installation. The valve is also suitable for use on other liquid lines for which the materials of construction are compatible.

Position of ball check indicates whether or not condensate is flowing
No need for separate check valve
Gaskets made from Glass reinforced graphite laminate
Horizontal or vertical fitting



  • Sight tube should be periodically checked for thinning
