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]

Load Holding Pressure Valve -- LHDV 33
from HAWE North America Inc.

Load holding valves are pressure valves, which act always on the returnflow side of double acting consumers. They block the return duct according to their set pressure (setting approx. 15% above the max. load pressure) generating a counter force to a pushing (negative) load. Thereforethe pump will...
