SPCV Integral Sight Glass /
Wafer Poppet Check Valve

The SPCV combines all the benefits of the CTSG tubular sight Glass with it’s 360 degree process viewing with an integral poppet check valve. The design is both space and cost saving whilst also helping with joint reduction in the process plant.

To Suit ASME 150 and Din PN10/16 Piping Systems


The SPCV has a heavy wall borosilicate glass viewing sections and PFA lined carbon steel flanges. The glass is supported with a robust stainless steel tie rod ‘cage’. The poppet check valve has a Hastelloy spring and glass filled PTFE poppet. The design incorporates  all of the benefits of the WPCV with a floating poppet and machined seat for effective sealing.  The SPCV tie rods can be adjusted without removing from the pipeline and can be fitted equally as well in horizontal or vertical applications.  All wetted parts are PTFE, PFA , Hastelloy and Borosilicate Glass.
