PV Series

Electronic Proportioning Control
Valve

OPERATION

The PV closes on power-up. If closed, the
motor will stall. This is normal. It then opens
to the position governed by the switch settings
shown below.

INSTALLATION

Mechanical Connections

Connect the valve to your pipes by screwing
the pipes into the unit. If you use TFE tape,
make sure there are no loose pieces in the
fluid stream. Use unions when possible for
easy removal for maintenance or repair. Use
hangers to support the weight of the unit and
to eliminate stress on the pipes. The
direction of fluid flow should match the
arrows stamped on the side of the valve
body.

Electrical Connections

Wire Color Functions

White (A) 4-20mA or 1-5VDC
Black (B) Common for 4-20mA or

1-5VDC
Red (C) 12 to 24 VDC
Red/White (D) Common
Green (E) Open Full
input, dry

contact closure
Green/White(F) Close Full input, dry

contact closure
Blue (G) Common for Open

and Close inputs

1-Close ON - Close full. 50% if Switch 2

also ON.

OFF - nothing.

2-Open ON - Open full. 50% if Switch 1

also ON.

OFF - nothing.

3-FIlter ON - Noise filter engaged.

OFF - Noise filter diesengaged.

4-DDR ON - Reverses action of Switches 1

and 2.

OFF - nothing.

5-Fail ON - Fail closed on loss of signal.

OFF - Fail open on loss of signal.

6-Range Active if Switch 7 is OFF.

ON - Selects hi range. 12-20 mA or
3-5 VDC.

OFF- Selects low range. 4-12 mA
or 1-3 VDC.

7-Split ON - Full range. 4-20 mA or 1-5

VDC.

OFF - Split range. See Switch 6.

8-ADR ON - Reverse action. Large control

signal causes valve to close.

OFF - Direct Action. Small control
signal causes valve to close.

Move Jumper JP2 from center and bottom
pins to center and top pins to switch from 4­20mA to 1-5 VDC control signal. This
disconnects 250 Ohm resistor and connects
the 3.3K Ohm resistor.
