Check Valves

Compact Check Valves

The low pressure-drop design of Marotta’s CVM series check valves makes them an ideal choice for a wide range of hydraulic and pneumatic applications that require a compact, lightweight package.

Marotta check valves incorporate a poppet with internal flow passages for minimal pressure drop. The poppet has a large L/D ratio, maximizing poppet guide and minimizing chatter, resulting in a very smooth operation. The valve uses soft seats for a bubble-tight seal. A variety of seat materials are available to ideally meet the application requirements.
