Oil electric-hydraulic control system is the key equipment to protect the pipeline system and
control the oil throughput at oil transportation station. The
control valve adopts V series ball valve manufactured by FISHER(in
US). The actuator adopts DDYZ series electric-hydraulic actuator
manufactured by Wuxi Sanxin Drive Control Co., Ltd. (we are the
exclusive agent of Wuxi Sanxin Drive Control Co., Ltd. in China
petroleum pipeline market). Using oil electric-hydraulic control
system to realize the automatic control of the oil pressure in and
out of station according to the actual situations in the oil
transportation station: when the automatic pressure adjust system
is used in pipeline safety protection, over-high outlet pressure
and over-low inlet pressure can be avoided in the oil
transportation station, when the automatic pressure adjust system
is used in the normal oil transportation production, throughput can
be controlled.
Standard Configuration
DDYZ-55 actuator
PUIC hydraulic station
SD handwheel actuator
Fisher valve body
Main Characteristics
Fast speed,up to 6~10S, the factory setting of 8S can meet the
requirements for pressure fluctuation control
Contactless closed loop negative feedback control
What is firstly witnessed in the world,the actuator is double cylinders structure with compact structure,
small volume, good cooling performance and standardized electric
signal control
Hydraulic parts and electronic magnification circuit board are
installed in the aluminum shell with good cooling performance and no leakage
The imported seal is used for output shaft seal
Complete self protection function, interrupt control signal,
interrupt power signal, interrupt oil pressure locked in situ and remote transmission alarm function
Quite high reliability, free maintenance within 6 years
