TWO STAGE VALVES
The three most common Liquid Controls meter systems
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
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
applications.
A2859-11 Valve and 3-Way Solenoid
A two stage valve with a S2 solenoid-operated valve
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
a bypass pipe that connects the inlet and outlet sides
of the control valve. It opens while the control valve is

.
E-7 Valves
A two stage valve with a S1 and a S2 solenoid-operated
closed valve using channels molded into its housing.
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
