TWo sTaGe valves
The three most common Liquid Controls meter systems
with two stage valves are: a block valve with a S1 and
a S2 solenoid-operated valve fitted onto external piping
(A2848-11), a block valve with a S2 solenoid-operated
valve (A2859-11) and a 3-way solenoid on the LCR-II,
and an E-7 valve with a S1 and a S2 solenoid-operated
valve.
A2848-11 Valve
This two stage control valve has a S1 and a S2 solenoid-
operated valve. The S1 solenoid-operated valve is
located at the meeting point of three bypass pipes: one
pipe from the inlet side of the valve, one from the top
of the block valve, and one from the outlet side of the
valve. The S2 solenoid valve is located on a bypass pipe
that connects the inlet and outlet sides of the control
valve. It opens while the control valve is closed to supply
the dwell flow. This valve is typically used in refined fuels
applications.
A2859-11 Valve and 3-Way Solenoid
A two stage valve with a S2 solenoid-operated valve
and a 3-way solenoid valve attached to the back of
the LectroCount LCR-II. The 3-way solenoid-operated
valve is located at the meeting point of two pipes from
the vapor eliminator (one for eliminated vapor and
one leading to the spit tank) and one pipe to the top of
the block valve. The S2 solenoid valve is located on
a bypass pipe that connects the inlet and outlet sides
of the control valve. It opens while the control valve is
closed to supply the dwell flow. This configuration is
typically specified for products that hold vapor in the line
such as LPG and NH
3
.
E-7 Valves
A two stage valve with a S1 and a S2 solenoid-operated
valve. The E-7 valve is fitted with one external pipe to
divert product flow to the closing mechanism. To supply
a dwell flow, the E-7 redirects the product around the
closed valve using channels molded into its housing.
This valve is typically used in refined fuels applications.
single stage valves (cont.)
A2700 Series Electro-Pnuematic Valve
Electro-pnuematic valves use a S1 solenoid-operated
valve mounted to a pneumatic actuator to open and
close a V-7 valve. These valves are typically used in high
viscosity applications like lube oil.

valve Installation
If installing the valve yourself, please refer to the valve’s
installation and operation manual for mechanical
installation. Instructions for wiring Liquid Controls valves
to the LCR-II are on the following two pages.
Materials needed for wiring valves:
not supplied
with the valve
• 18 AWG stranded wire (3 per solenoid). Not necessary for
3-Way solenoid valves. Only 2 needed for E7 solenoids.
• Weatherproof flexible conduit, ½" diameter and ½" NPT
conduit connectors or cable glands
• PTFE tape or pipe sealant
To wire valves to the lCr-II:
1. Attach cable glands and/or conduit connectors to the
solenoid valve(s) and the LCR-II port(s).
2. Thread the wires through piece of weatherproof conduit
that is cut-to-length from the solenoid to a LCR-II port.
3. Run the weatherproof conduit between the solenoid-
operated valve(s) and the LCR-II housing, pull the wires
through the ports, and tighten the connectors.
4. Connect the S1 solenoid-operated valve wires to
terminals 14 and 15 on the J13 terminal block of the LCR-
II CPU board.
5. Connect the S2 solenoid-operated valve wires to
terminals 17 and 18 on the J13 terminal block of the LCR-
II CPU board.
To wire a single stage valves for presetting:
1. Wire the S1 solenoid as instructed above.
2. Run a jumper wire from Terminal 15 to Terminal 18.
Disconnect the power before working on the CPU board.
Disconnect Power
Solenoid operated valve 81527 (3-way LPG solenoid)
has 3 cables potted into the housing. All other
solenoid operated valves on Liquid Controls valves
use cable assembly 81859, which has 2 cables.
Solenoid Operated Valve Cables
The Earth grounds for Terminals 16 & 19 are optional.
The solenoid operated valves are grounded through
the component they are mounted on.
