YTC Type Valve Positioner

YT1000R+PTM+410B L/S Electro Pneumatic Valve Positioner

Rotary positioner + PTM + 410B limit switch, assembled

A factory-assembled stack: rotary positioner, position transmitter module and a Model 410B limit switch box. It ships as one item so the buyer is not aligning three separate products on the actuator shaft.

Positioner, PTM and 410B limit switch assembled and aligned at the factory
410B switch box carries Exd II BT6 / Exd II CT6 protection and IP67
410B connection 2×G1/2, 8 terminals, on-yellow / off-red indicator
Mechanical or inductive micro switches selectable
Explosion-proof positioner variants Ex dm IIB T5 / IIC T5 / Ex ia IIB T6

Technical background

Type YT-1000R Electro-pneumatic valve positioner is used for operation of pneumatic rotary valve actuators by means of electrical controller or control system with an analog output signal of DC 4 to 20 mA or split Ranges.

YT1000R Electro Pneumatic Valve Positioner- Brief introduction of electro valve positioner Valve positioner, adjustable and switch type, single and double acting plus explosion-proof, with feedback, etc.

with linear stroke/angle stroke/ and single and double acting/additional accessories YT-1000RD13/YT-1000LS33 (explosion-proof type YT-1000RDM13) ( Electric positioner with feedback, YT-1000RD13+PTM) (intelligent valve positioner YT-2300) -(YT-2400-) (Electro positioner YT-1300) There are also gas-pneumatic positioner, Fisher positioner, Siemens positioner, Yamatake positioner, YTC,ROTORK,SMC,METSO,FLOWSERVE intelligent positioner, electro converter, etc.

What is an electro valve positioner? The YT1000L electropneumatic valve positioner refers to changing the output signal of the electric controller into a pneumatic signal to drive the pneumatic actuator. It has two functions: an electric-pneumatic converter and a pneumatic valve positioning device.

Questions buyers ask

Why buy the stack assembled?

Because alignment of switch cams, transmitter and positioner feedback on the same shaft is the fiddly part; the factory does it before the unit ships.

What protection does the 410B give?

Exd II BT6 and Exd II CT6 with IP67, over a -25 to +85 °C range.
