characteristics

OMA equips several aircraft and helicopters with Non-Return Valves.

Metal-to-metal and soft-to-metal seats are alternatively designed and manufactured in order to meet the most demanding low and zero leakage requirements.

Non-Return Valves generally consist of a stainless steel body containing a stainless steel poppet and a stainless steel spring entrapped in the body through a stainless steel end stroke.

The poppet end is often drilled by several orifices in such a way that the resulting pressure drops are in accordance with the design requirements.

For foulproofness purposes the NRV hydraulic inlet and outlet ports are designed with different sizes in order to avoid inadvertent wrong installation.
