Ammonia (NH3) applications
For all larger valve types an ammonia element is
available. These elements have style 15
pressure connection and consist of a stainless
steel bellow in a steel cup (coated). The existing
element can be replaced by this ammonia
element. The pressure range does not change.
For the high range valves the spring inside the
power element has to be placed in the ammonia
element. If low-pressure range is needed this
spring can be removed. For low quantities you
have to order the selected valve and separate
ammonia replacement power element (see valve
type selection table). For quantity orders a
special valve type can be set up. Then please
contact the JC sales office in your region.
Each KIT contains parts as
indicated in the table below.
The complete KIT must be
ordered that contains part
required.
