All-Welded Check Valves

            CW Series      

CW Series All-Welded Check Valves are designed with an internally threadless, all-welded body, supporting a maximum working pressure of 3000 psig (206 bar) and a cracking pressure of less than 2 psig (0.14 bar). The standard surface roughness is finished to Ra 20 μin. (0.51 μm), with electropolished wetted surfaces as an option. These valves are suitable for high-purity and ultra-high-purity applications.
