RV-E Series ELECTRIC ROTARY VALVES - (Valve head assembly - no motor)
Economic PTFE/PCTFE Rotary Valve option for OEM clients with knowledge and experience with mounting their own
stepper motors.
•
Inert flow path - only the PTFE valve body and PCTFE rotor
are in contact with the fluid
•
1/4”-28 UNF, flat bottomed fluid connection ports with
stainless steel threaded inserts for extra strength and
durability
•
A two-channel optoelectronic position sensor and optical
encoder disc are incorporated into the valve. This position
sensor allows for referencing the “home” position after the
unit is powered up and for signalling that the valve has
reached a valid “port” position
•
Incorporates an internal coupling that mates the valve’s rotor
to the driving source
•
Mounting dimensions fit NEMA 17 stepper motors
