Crane Stockham Duo-Chekstainless steel wafer type, dual plate check valve, according API 594. Metal seated, suitable for mounting between ASME B16.5 RF Class 300 flanges.
Tested according API 598. Materials comply with NACE MR-01-75. EN 10204-3.1 test and material certificate is available.

This check valve is characterized by the compact, lightweight and balanced disc design, that stands for a fool proof operation, an efficient flow characteristic and low installation costs.
The independent operating, long springs ensure a long life span end a "non-slam performance”.
Because of the “retainerless” design there are no body penetrations, so fugitive emission to the atmosphere is not possible and the valve is inherently fire-safe. This makes the valve suitable for heavier, critical applications.

Applications:
On- and offshore installations in (petro-)chemicalandoil & gas industry.Clean gasses and fluids, to prevent backflow and protections of pumps and compressors.

Application

Recommended in: Chemical, Petrochemical and Refining
