AVM HYDRAULIC POWER UNIT

Hydraulic Power Unit

Tailor Made Design

All features available, from simple on/off to advanced controls, such as regulation or fail safe.

Why use Hydraulic Actuators?

Can be used instead of any mechanical drives, either manual or electrical
Can be a simple cylinder to operate the valve in a linear movement (i.e. gate valves) or combined with some a mechanism for rotational duty (i.e. butterfly valves, ball valves or plug valves)
Hydraulic actuation allows the designer many options, i.e:

– Different force/torque and speed can be applied at open/close or in different stages of opening/closure.
– Emergency closure (failsafe) with lever and weight assembly.
– Secondary pumps in case of pump failure (not possible for electric systems).
– Can operate 24/7 continuously.

AVM Hydraulic Power Unit (HPU):

Hydraulic Power Units usually consist of the following equipment:

Motor(s) and hydraulic pump(s) to create the hydraulic pressure
Pressure control valves to by-pass overpressure to the tank
Manual and/or solenoid valves for directing flow to the required side of the cylinders
Flow control valves to control speed of operation
A hydraulic block combining these valves in a compact design
Filters at suction and/or pressure side
This equipment is assembled onto an oil tank, which is the oil reservoir
Heater and/or cooler systems when necessary
Oil level sensor
Oil level gauge
Pressure gauge
Temperature sensor, if needed
Control box, i.e. an electrical cabinet for controlling this equipment
In addition to the hydraulic equipment quality/price level, the following equipment can be tailored to meet the client’s needs and requirements. These selections have a cost impact as well.
