type valve is a double throttle/check valve. Two
symmetrically positioned against each other
throttle/check valves limit through adjustable throttle
(throttling piston) size of the flow in one direction, and
allow free flow in the opposite direction through the
check valve. The valve is designed for sandwich type
mounting - it is usually installed between the subplate
and the valve of the same nominal size and is used for
limiting the size of the main flow (changing the speed
of movement of the receiver).
Hydraulic fluid from the port
A
AA
A
flows through the
throttling slot (1) to the receiver. At the same time, the
fluid under operating pressure flows through port (2) to
the side (3) of the piston (4) which is loaded with the
spring. The piston (4) is therefore maintained in the
throttling position both by the force of the spring and the
hydraulic force. The fluid returning from the receiver
moves the piston (5) to the right and allow free flow of
the fluid through the valve system (throttling insert)
which now acts as a check valve.
