FUNCTION
The P2SRR6 is a direct acting 2-way
flo
w control valve.
Flows from port A to B are controlled
independently of the pressure. In the
opposite direction there is free flow
trough the check valve. The controlled
flow rate is proportional to the
electrical input signal at the coil.
Analogue to his size the coil creates a
force which pushes the piston against
the spring. Hereby opening diameters
are opened which determine the size
of the flow independent from the
pressure differential
A built-in pressure compensator
enables the regulation independent
from pressure changes from port A to
B.
For the electronical control there are
electronic controls available (see
separate brochures).
