Product Overview
Sandwich Check Valves for Instrumentation Lines
The design and manufacture of FLOEC Single Disc Spring Loaded Check Valves is done as per DIN 3230. The valve is designed to mount between flanges of different standards and in whichever direction is needed. It is well suited to instrumentation, especially pneumatic and vacuum applications, as it is offered in both metal-to-metal and soft sealing options.
It is offered in cast iron, S.G. iron, cast carbon steel, and stainless steel of every grade, and in high alloys like Alloy-20, CD4MCu, duplex, super duplex and Hastelloy. Sizes range from 15 NB to 150 NB and pressure ratings from ASME 150# through 2500#.
Typical Applications
- Instrumentation
- Pneumatic Lines
- Vacuum Systems
- Utilities
- Chemical
