SDNR Valve
An SDNR (Screw Down Non-Return) Valve is a critical flow-control valve designed to allow fluid flow in one direction while preventing backflow. It combines the functions of a globe valve and a check valve, making it ideal for applications where controlled shut-off and non-return protection are required.
