3-Way Pneumatically-Actuated Control
Common Features
Honeywell offers a wide selection of
pneumatic actuators:
• VFF3 – A-B-AB porting, full-cut (150-175 psid
close-off) or under-cut disc (50 psid close-off)
(Figure 1 - from 63-2661-02 g. 12)
• VFF6 – A-AB-B porting, full-cut (150-175 psid
close-off) or under-cut disc (50 psid close-off)
(Figure 2 - from 63-2661-02 g. 12)
• 20 psi spring return (up to 8" size)
• 80 psi spring return
• 80 psi double acting bi-directional
• Mixing or diverting control
• Standard right-angle cast-iron T-pipe
• A-port congured to closed position at factory
• Porting pattern eld-congurable with valve
linkage adjustment
Notes:
Viewed from above
P = Actuator and Primary Valve
S = Slave Valve
VFF3 valve action is mixing for uid ow from
left to right.
VFF3 valve action is diverting for uid ow from
right to left
VFF6 may be piped for mixing control with water
exiting port AB, or for diverting control with
water entering port AB
