Check_valve:
The check valve permits flow in one direction only.
A small check disc within the housing ensures free flow in
one direction and at the same time seals off on the other side.

Restrictor_check_valve:
The restrictor check valve provides a constant flow in one
direction, defined through the orifice size, and a flow of the
full nominal size towards the other direction.
