Check Valves

Compact Check Valves

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

Check valves are used to achieve single-direction flow, via springs, hinges or other design elements to shut down the reverse flow direction when a pressure threshold is reached. A check valve system is a critical component of correct flow direction of fluids, liquids, hydraulics, oil, gas, air and other media — preventing backflow and potential damage, malfunction, shutdown, and danger to operators and other personnel.

Typical uses of check valves include aerospace check valves, aircraft check valves, space check valve systems, and more — all of which are safety-critical uses where quality and reliability are paramount concerns.
