Type 3660 and 3661 Positioners

The Type 3660 pneumatic (see figure 1) or Type
3661 electro-pneumatic, single-acting positioners
are used with various actuators on sliding-stem
valves for throttling applications. These rugged
positioners provide a valve position proportional to a
pneumatic input or a standard milliampere dc input
signal received from a control device. More Info

3610J and 3620J Series Positioners

The Type 3610J or 3610JP pneumatic and Type
3620J or 3620JP electro-pneumatic positioners are
used in combination with either single or double
acting rotary actuators to accurately position control
valves used in throttling applications. The positioner
mounts integrally to the actuator housing. These
rugged positioners provide a valve position
proportional to a pneumatic or a dc current input
signal. More Info

3582 Series Pneumatic and Type 3582i Electro-Pneumatic Valve Positioners

The 3582 Series pneumatic valve positioners, shown
in figure 1, and the Type 3582i electro-pneumatic
valve positioners, shown in figure 2, are used with
diaphragm-actuated, sliding-stem control valve
assemblies. The pneumatic valve positioners receive
a pneumatic input signal from a control device and
modulate the supply pressure to the control valve
actuator, providing an accurate valve stem position
that is proportional to the pneumatic input signal. More Info

Type i2P-100 Electro-Pneumatic Transducer

The Type i2P-100 electro-pneumatic transducer,
shown in figure 1 uses a patented converter module
that converts a milliampere input to a proportional
pressure output. Both the current input and pressure
output range are user-configurable in the field. The
converter module uses small parts of minimum
mass, which are balanced symmetrically around a
pivot point at the center of the mass. This balanced
arrangement results in a high performance
instrument that reduces sensitivity to vibration. More Info
