Miniature Low Cracking Pressure Check Valve -- CKV
from Beswick Engineering Co., Inc.

The check valve permits free flow in one direction and no (checked) flow in the opposite direction. This valve is specified in many applications because of its very low cracking pressure (typically less than 0.5 psig), its excellent repeatability, and leak-tight operation. The unique design of the... [See More]
