GAS OVER OIL ACTUATORS

Features
Designed to be used for automatic operation of line
valves and operates with line pressure (natural gas)
or externally supplied gas pressure (air, nitrogen).
Actuators operating at different pressures are available
upon request. It can even operate full-automatic way in
all weather conditions where nobody and no electric
power exist. Various types are available depending
on the geographical requirements, engineering
requirements and operating conditions. Suitable
solutions can be derived depending on the intended
use, pressure changes, climate, area, mounting and
maintenance conditions.
Available pressure range of the gas where the actuator
used is the determining factor. Our actuators in general
are provided with following options;
• Standard types operating at a pressure between 10
and 110 bar,
• Customized manufacture option for different pressure
ranges.

MAIN PARTS OF ACTUATOR

Scotch Yoke Mechanism

Main power transition system of quarter turn

actuator which is used for ball and plug valves.
The canted Scotch Yoke Mechanism performs the
opening/closing process by turning the horizontal
movement of the hydraulic cylinders into 95°
rotational movement. Moreover, as it is canted, Scotch Yoke Mechanism & Hydraulic Cylinder

torque gain is supplied in the regions where critical

torque levels required.

Hydraulic Cylinder
Main movement transition unit to scotch yoke
mechanism, operated by hydraulic oil pressure. The
gas pressure of the control unit generates horizontal
power to hydraulic pistons by compressing the oil in
the gas- hydraulic tanks.

Gas-Hydraulic Tank
Tubes that hydraulic oil is stored in and compressed
via gas when required.
Gas-Hydraulic Tank

CAT- GO- 20R0
 GAS OVER OIL ACTUATORS (GO)

STANDARD ACCESSORIES
Emergency Hand-Pump
Used for emergency cases and for manual operation
without using pressurized gas. The pump is
equipped with a 4-ways control valve for open, close,
automatic and by-pass positions. There is also a
locking device to prevent unauthorized operations.
Whenever the gas pressure is required for operation,
the lever should be positioned on “AUTO”, otherwise
the lever is kept at relevant position and actuator is
operated through hand pumping. By-pass position
Emergency Hand Pump
is used to balance the oil level of oil tanks after
bringing the actuator in the middle situation.

Hydraulic Filter
Provides cleaning of system oil and adjustment of
open/close period.

Hydraulic Filter

Unidirectional Flow Regulator

Speed is adjusted by unidirectional flow regulator for
types with manual hand pump.
Unidirectional Flow Regulator

Torque Limit Switch

The torque created by actuator is proportional with
the gas pressure, and the limits prevent creation of
over torque for operation of the valve. When pre-set
value is exceeded, gas pressure is relieved and risk
of over torque is prevented.
Torque Limit Switch

Gas Filters
All power and instrument gases used in GO
actuators are filtered & cleaned. Micron level is
determined upon request. Filters should be cleaned
by intervals depending on usage frequency. More
precise filtering system is available upon request.

CONTROL UNITS
Contains power and control elements of actuator,
which are responsible for opening and closing
process. Controls main gas supply to gas-hydraulic
tanks.

Control Unit (GOCA)

Local Control (L)

Manual operation of valve locally by means of gas
pressure activated with open/close buttons located
on actuator. This is a standard feature for all GO
actuators. When buttons or levers marked “open” or
close on the actuators are pressed by the operator,
line gas fills in gas over oil tubes and compressing
the hydraulic cylinder moves the scotch-yoke
mechanism which opens or closes the valve.

Local Control(L)

Remote Control (R)

Remote operation of valve from the control panel.
Two solenoids are located on the actuator; each
being used for open and close the valve. Standard
control voltage is 24V DC. Different working voltage
is available upon request. Through electrical line
between the valve and control panel, signals are
sent to solenoid valves. Connection line is also used
to receive information of valve position and pipeline
condition. Additional control options and solutions
are offered, considering the requirements of end-
user.
Remote Control(R)

CAT- GO- 20R0
 GAS OVER OIL ACTUATORS (GO)

Differential Pressure Switch (DPS)

GO actuator should not operate under high
differential pressure in order to prevent the valve
and the pipeline from damage. When differential
pressure exceeds the factory setting, valve will not
operate via local or remote control. Opening of valve
under high differential pressure can cause damage
on trim material and the pipeline itself. Standard
set range is 1-7 bar. Other rates are available upon
request.

Pressure Controlled Emergency

Shut-Down (ESD)
Differential Pressure Switch (DPS)
It is used when the actuator is required to shut
down the line during emergency cases that are
determined. ESD system is activated in case of
pressure drop during break or explosion of line and
closes the valve.

Alternative choices may be used for this type;

• Low Pressure Control (LP): When control is desired
for low pressure opening or closing,
• High Pressure Control (HP): When control is
desired for high pressure opening or closing,
• High & Low Pressure Control (LP&HP): When
control is desired for low and high pressure(LP&HP)
opening or closing.
Pressure Controlled Emergency Shut-Down (ESD)

Pneumatic Line Break System (LB)

It is designed for gas lines. It is a process where
actuator switches off the valve automatically

once the drop speed of gas pressure is over the

preset level. There is no need for any electrical
power to perform this process.

Pneumatic Line Break System (LB)

C A T - G O-20R0
GAS OVER OIL ACTUATORS (GO)

Liquid Line Break System (LLB)

It is a line break control system; designed for liquid,
liquid-gas mixture systems. It is a process
where actuator switches off the valve automatically
once the drop speed of gas pressure decrease is
over the preset level (for example 3,5 bar/min). There
is no need for any electrical power to
perform this process.

Liquid Line Break System (LLB)

Control Voltage Loss Detector (CVLD)

It must be added for control of automatic operation
at voltage loss.

Control Voltage Loss Detector (CVLD)

OPTIONAL ACCESSORIES
Gas Storage Tank (Reservoir, Z)
A reservoir tank must be added if at least one
opening closing cycle is desired when the line
pressure is not available.

Gas Storage Tank

Fireproof Blanket
The risk of fire and explosion is extremely
considerable to refinery, gas processing,
petrochemical and offshore installations. Fireproof
blankets wrap around the actuator and protect it
from the harm and damage caused by fire.

SELECTION OF ACTUATOR
Following information is needed when selecting the
actuator;
1. Torque values of the valve; Break Torque to Open
(BTO), Run Torque to Open (RTO), Run Torque to
Close (RTC). Selected actuator should have a torque
value is %40 over than the max torque needed for
the valve.
2. Flow direction and gas pressure (max, min, norm).
3. Stem diameter & dimension of connection key.
4. Actuator connecting flange standard as per
ISO5211, or short code(FXX) or dimensions.
5. Valve Datasheets & Actuator Datasheets should
be reviewed & answered in details. Additional
requirements should be indicated.

Assembly
Assembly of actuator (GO) on the valve should
be executed by an experienced & qualified team.
As a side note, suitability of mounting-flanges &
stem diameter should be checked and actuator is
mounted on the valve by lifting through its hooks.
Actuator equipped valve shall be assembled
between the proper space left on the pipeline,
considering up and down-stream direction.
Vastas supervisor would witness the assembly and
make the necessary adjustments.

Service
Whenever service is required, Vastas authorized
service team is always ready to collaborate.

Maintenance
All GO actuators should be undergo a periodic
maintenance annually. Vastas service team which is
strongly recommended, would control of gas filters,
oil levels, hydraulic hand pump etc. and to review any
defected item. Calibration of LB, ESD, torque limit Vastas professional and
pressure adjustments should be also considered. qualified service team is ready
