PNEUMATIC POSITIONER F10 :
The Posiflex-Pneumatic Positioner is a simple, single stage,
displacement balance instrument suitable for either linear
or rotary actuators.It provides stepless positional control
for a wide variety of pneumatic actuators. A single universal
model can be used for both double acting and single acting
The basic design incorporates a high enhancement flapper
and nozzle spool valve and adjustable range and reversing
Three Position Cam for Rotary Actuators provides for linear,
quick opening and equal percentage characteristics. A special
cam for rotary actuator provides for split range.
ELECTRO-PNEUMATIC POSITIONER F20 :
The F20 is a universal Electro-Pneumatic Positioner, suitable
for either linear or rotary actuators (single or double acting).
The F20 Positioner operates on the principle of analog electronic
comparison. An analog 4-20 mA input signal is used to obtain
an accurate position of the actuator.
The F20 is a true 2 wire instrument, with the 4-20 mA signal
providing both the controlling signal and power supply for
the electronics. An electronic module provides all the usual
control characteristics; zero, range and sensitivity. They
are all electronically resetable using trimmers on the control
A comprehensive range of integrated control options include
gauges, switches and position transmitters. Mounting is to
the Industry standard VDI/VDE 3845 (Namur) or IEC 534/6. The
drive coupling for the rotary version is spring loaded for
OPTIONS AVAILABLE FOR POSITIONERS :
- Position Transmitter
- Limit Switches
SMART POSITIONERS :
Smart positioner are microprocessor-equipped,
current pneumatic smart valve positioners for pneumatic
The smart positioner receives a DC current signal from control
devices and controls pneumatic valves. In addition to this
basic function, the positioner has communication capabilities,
automatic conﬁguration program, and self-diagnostics functions
that will greatly increase productivity and the efficiency of
El-O-Matic supply’s SMART type Positioner from Various Global
Manufacturers like Siemens, ABB, Metso, Fisher, etc.
PARTIAL STROKE TESTING DEVICE (PST) FOR ESD VALVE :
“In an emergency, the ability to rapidly shut off fluid
and/or gas flow can mean the difference between a manageable
situation and a potential disaster”
What is PST?
PST (Partial Stroke Test) is a function test used to check
periodically that ESD valve is operated securely without any
non-conformities such as sticking (Jamming) of valve &
actuator in the event of emergency, by closing the valve
slightly & slowly to such range as not to interfere with the
process during plant operation.
What device is used for PST?
Partial stroke Testing (PST) is performed by a SMART
Positioner type Device having facility to perform PST. The PST
device consists of a smart positioner with PST function
attached to a pneumatically operated actuator, and is
available in “HART” or “Foundation Fieldbus” type. The smart
positioner is multi-functional, as it is incorporated with a
El-O-Matic Supply’s valves for ESD Application to Cater
today’s Process Industry safety need.
