4600 Series Pneumatic
Positioner
General:
The 4600 Series Pneumatic positioner are field
proven
positioners utilizing a precision feedback cam to
provide
accurate positioning, very fast response, and
customized
control characteristics for control valves. These
positioners can
be used with either rotary or reciprocating
actuators. When
mounted on reciprocating actuators, a simple, rugged
turnbuckle and lever assembly couples stem motion to
the cam.
On rotary actuators, the cam is mounted directly on
the shaft.

8100 Electropneumatic Positioner
The 8100 Series Electropneumatic positioner
are produced
with Masoneilan Technology.
The positioner is a force balance,
electropneumatic device
which provides an accurate means of obtaining a
valve stem
position directly proportional to a DC input
signal. In addition,
the positioner provides a convenient means of
split ranging
the controller output signal. It may have either
direct or reverse
action on either direct or reverse actuators.

8200 Series Electropneumatic
Positioner
General:
The 8200 Series Electropneumatic positioner are produced
with Masoneilan Technology.
The positioner is an electropneumatic force-balance device
which provides an accurate means of obtaining at any time a
valve stem position corresponding to a theoretical position
envisaged for a DC input signal. In addition, the positioner
provides a convenient means of split-ranging operation for
several valves (usually two) from a single signal emitted by a
single controller. The positioner may have either direct or
reverse action on either direct or reverse actuators.

ZPD2000 Electro-pneumatic
Positioner
ZPD-2000 Electropneumatic positioner is used
with the pneumatic control valve. It receives the electric
signal from the
regulator and outputs the pressure signal to control the stroke
of the control valve. The positioner can improve the operating
characteristic of pneumatic control valve and overcome the
friction of the plug stem and the unbalanced force of the valve
plug
induced by change of the medium pressure, thus the position of
the valve changes with the control signal from the regulator in
proportion, so that the proper positioning can be attained.

ZPD3000 Series Electro-pneumatic Positioner
General:
ZPD 3000 series electro-pneumatic positioner, mounted
on a pneumatic actuator, moves the actuator by receiving DC
4 20 mA signals from a controller. Also, the function of
detecting and returning the actuator displacement provides
accurate positioning in response to DC 4 20 mA signals.
The ZPD 3000 can be used with both single and double
acting actuators.

ZPD ZPQ Valve Positioner
The valve positioner (Electro-Pneumatic or Pneumatic) is
used with the pneumatic control valve (diaphragm or piston).
It receive the electrical or pneumatic signal from the
regulator and outputs the pressure signal to control the
stroke of the control valve. The positioner can improve the
operating characteristic of pneumatic control valve and
overcome the friction of the plug stem and the unbalanced
force of the valve plug induced by the change of the medium
pressure, thus the position of the valve changes with the
control signal from the regulator in proportion, so that the
proper positioning can be attained.

Digital Positioners
The MASCOT YT-2400 High Performance Digital
Positioner utilizes a powerful 16 bit micro processor and two-stage
poppet relay mechanism to provide exceptional response and
positioning accuracy.
