Description

The ZDE3K* are explosion proof proportional pressure reducing direct operated pressure valves, for subplate mounting. They are compliant with ATEX, IECEx, INMETRO or PESO requirements and are suitable for use in potentially explosive atmospheres, for surface plants or mines. A low temperature version (up to - 40 °C) is also available. They are used to reduce pressure in the secondary circuit branches thus ensuring stability of controlled pressure in the event of variations of the flow rate through the valve. Adjustment available on A, B or both. The valves are available with 12 or 24 V solenoid. Several connection types are available, metric or NPT type. Cable glands are available.
