output is regulated using mechanically controlled variable inlet ports in each
piston pumping chamber. Output flow is adjusted by the linear movement of a
spring-biased volume control stem. The models listed in the table deliver
zero flow with the stem control in the fully extended position.

Pressure
Compensated 压力补偿
These pumps are mechanical variable delivery with an integral pressure
compensator. The compensator overrides the setting of the maximum volume
control. The models in the table deliver full flow with the stem
control in the fully extended position.

Electrohydraulic Pressure Compensated 电液压力补偿
Electrohydraulic volume control is achieved using a Dynex Remote Proportional
Actuator (RPA). The bracket-mounted actuator strokes the pump volume control
stem. Contact the Dynex sales department for information on adding
electrohydraulic control to the PV6000 Series compensated models shown above.

Hydraulic Variable Delivery
液压可变输送
Pump output is regulated by a variable low pressure signal, 0 to 180 psi (0 to
12 bar), supplied to a control port in the pump cover. Pump volume controls,
including remote pressure compensators, are available.
