DIN Marine Butterfly Valve
The DIN Butterfly Valve is a butterfly valve that conforms to the DIN EN593 standard. The main types of DIN butterfly valves are plate type, lug type and flange type; the sealing form is divided into hard seal and soft seal; the nominal diameter range is DN40-DN1500; the main materials are bronze, cast iron, cast steel, stainless steel, etc. The main materials are bronze, cast iron, cast steel, stainless steel and so on.
Overview
Material:
Metal-sealed DIN butterfly valves need to choose suitable metal materials to meet the requirements of high temperature and high pressure. Usually the materials used are stainless steel, carbon steel and high temperature steel, etc., while the soft sealing de standard butterfly valve needs to choose rubber, PTFE and other materials for sealing.
Feature:
The specific provisions of the DIN butterfly valve structure length standard depends on the nominal diameter. In the nominal diameter DN5O-DN400 range, the DIN butterfly valve structure length standard mainly includes A, B and C three levels. In class A and B, the length of the AB level each take less than a specific length (such as in DN50 nominal diameter, the length of the AB level were less than 125mm and 130mm); in the C level, the length of the length can be more than a specific length, but the length of the exceeding shall not exceed 10%.
