VEP-3420 / 3421 Series 3/4" & 1" Electronic Control Valves 3-Way Diverting
Fail-Safe
The VEP–3420 and VEP–3421 series are 3–way diverting, zone
valves available in 3/4" and 1" line sizes designed to regulate hot or chilled
water in VAV terminal unit reheat coils, fan coil units and induction units. The
compact size allows easy installation in small enclosures. The fully enclosed
electric actuator has heat resistant lead-wires and is readily installed or
removed, via a screw-on ring nut.
These valves utilize three different types of actuators:
The MEP–3001 (24VAC) is used for systems requiring 2-position fail-safe (full
flow) operation. The unit utilizes a PTC thermal element for dependable
long-life and noise-free operation. The MEP–3010 is a tri-state actuator which
requires separate 24 VAC signals to drive the actuator open
or closed. With both signals off, the actuator is motionless.
The MEP–3011 proportional actuator requires a 24 VAC power source and a 2 to 10
VDC input signal to drive the actuator. The proportional actuator
powers down at the full open or closed position. The proportional actuator also
recalibrates the closed to open stroke to the control signal after 4000 cycles,
or after a power failure.
