Concept
CPMI-2, CPMI-D60 and CPMO-2 are sanitary constant-pressure
valves. CPMI-2 and CPMI-D60 (Constant-Pressure Modulating Inlet)
maintain a constant pressure in the process line at the inlet side of
the valve. Typical applications are after separators, heat exchangers
or overflow valves. CPMO-2 (Constant-Pressure Modulating Outlet)
maintains a constant pressure in the process line at the outlet side of
the valve. Typical applications are before filling/bottling machines etc.
Working principle
The valves are remote-controlled by means of compressed air. A
diaphragm/valve plug system reacts immediately to any alteration of
the product pressure and changes position so that the preset pressure
is maintained.
Standard design
The CPMI-2 and CPMO-2 consist of a valve body with valve seat,
cover, a valve plug with a diaphragm unit and a clamp. The cover and
the valve body are clamped together. The valve body and the seat are
welded together. The CPM-I-D60 consists of upper and lower valve
bodies, an inlet tube, a cover, a valve plug with diaphragm unit and
clamps. The cover and the valve bodies are clamped together.
