Screw Down Non Return Valve (SDNR)

IMR Screw Down Non Return Valves are used to prevent reverse flowing when in ''open'' position and provides a leak-tight shut off with the capability of being used while partially open to regulate flow. The valve combines the functions of a globe valve and that of a check valve and it is mainly used on marine vessels. Our valve designs with disc are not attach to spindle and complete guidance to ensure it seats correctly when the valve is closed.
