Valves and fittings for marine service Mud boxes Cast iron Econ® mud boxes are installed in suction pipes aboard vessels to protect pumps against large solids. The standard perforation size of the strainer basket is 8 mm square; the cover is mounted with studs and hexagon nuts. As an option the hexagon nuts can be replaced by brass bow nuts. The cover is provided with a blind boss, suitable for mounting an air vent. These mud boxes are also used for applications on shore, for example in swimming pool installations.

Low resistance Econ® mud boxes offer a very low resistance, which is partially due to the large free straining surface, which is on average about 6 times as large as the pipeline diameter area. When the strainer basket is about 85% fouled, the flow through the strainer basket is still equal to the diameter area of the mud box. Material specification Comp onent Material EN and/or (DIN) W.nr.
