Installation
New Installations
When ordered with a new meter, the A3982 Series E15 valves are mounted to the meter at the factory. The valve solenoids are prewired to the LCR-II, LCR600 or LCR.iQ electronic register and optical or mechanical air eliminators at the factory. Connect the system piping to the 3" flange on the outlet side of the valve.
[Diagram Description: Image shows three Liquid Controls E15 valves mounted on associated meter systems. The valves are yellow with various electrical connections and piping. Two systems on the left appear to be LCR-II or LCR600 registers, while the system on the right appears to be an LCR.iQ register.]
WARNING!
Safely Evacuate Piping System
Before disassembly of any meter or accessory component:
ALL INTERNAL PRESSURES MUST BE RELIEVED AND ALL LIQUID DRAINED FROM THE SYSTEM IN ACCORDANCE WITH ALL APPLICABLE PROCEDURES
- Pressure must be 0 (zero) psi.
- Close all liquid and vapor lines between the meter and liquid source.
Failure to follow this warning could result in property damage, personal injury, or death from fire and/or explosion, or other hazards that may be associated with this type of equipment.
Retrofit Installations
Depending on the existing configuration, adding a 2-stage E15 valve may require modification of the outlet piping. After the internal pressure is relieved from the system, the outlet line can be disconnected from the existing valve being replaced. The new E15 valve assembly can then be connected to the outlet side of the positive displacement meter. Use the four studs, nuts, and washers to fasten the valve assembly to the meter. The valve housing has an arrow showing the direction of flow. Ensure that the valve is properly oriented. Tighten the nuts in a crossing pattern. Once this is complete, the outlet piping may be reconnected to the outlet side of the E15 preset valve. The valve mating flange is 3" (NPT or Weld).
Wiring schematics for each of the models are covered on page 7.
NOTE: If used with a mechanical air eliminator, new valve plates (Buna: 42822, 42844 or Viton 43778, 43934) will need to be ordered and installed for proper operation of the E15 valve.

Electrical Sequencing
LectroCount LCR, LectroCount LCR-II™, LCR.iQ®
[Diagram Description: A timing diagram illustrating the electrical sequencing of Solenoid 1 and Solenoid 2 during a delivery cycle. It shows states like "Solenoid OFF" and "Solenoid ON" for each solenoid, correlated with flow states: "No Flow", "Full Flow", "Dwell Flow", and "Solenoid ZERO Shutoff is Self Adjusting". Solenoid 1 is ON during Full Flow, then OFF during Dwell Flow. Solenoid 2 is OFF during Full Flow, then ON during Dwell Flow.]
WARNING!
SOLENOID WARNING: The earth ground to the green screw on the solenoid terminal block is not essential for the operation of the device. In a truck application the solenoid is automatically grounded to the truck chassis via the liquid carrying piping. Check any applicable electrical codes to comply with proper grounding procedures.
Operation
The E15 Valve has two solenoids to control the two-stage closure of the valve.
| Solenoid | De-Energized | Energized |
|---|---|---|
| S1 | Port C and Port B Connected | Port B and Port A Connected |
| S2 | Valve Closed | Valve Open |
Two-Stage Closure
During full flow, solenoid valve one S1 is energized and solenoid valve two S2 is de-energized. During dwell flow, S2 de-energizes to end delivery. Shut-off during dwell flow reduces the risk of liquid hammer and accurately ends preset deliveries.
Valve Closed
When the E15 Valve is closed, the S1 and S2 solenoid valves are both de-energized and it is not possible to make a delivery. Fluid pressure from the pump enters the S1 solenoid valve at Port C and exists through Port B to the back side of the E15 piston. Pressure from the internal compression spring and pressure from the pump seal the piston against the inlet port of the valve.
[Diagram Description: A cross-section of the E15 valve showing the piston in the closed position. Fluid pressure enters at Port C, passes through S1 (de-energized) to Port B, acting on the back of the piston. The piston is shown sealing against the inlet port. A spring is also depicted.]
Full Flow
At the start of a delivery, the S1 solenoid valve energizes. This opens the path between port B and Port A, resulting in the liquid pressure on the back side of the piston to escape through the limited bleed hole in the Air Eliminator. This allows the pump pressure at the inlet port of the E15 Valve to push on the piston, compress the spring and force the piston toward the back of the valve housing. This opens a path for the liquid to pass through the valve. The S1 solenoid valve remains energized during the full flow portion of a delivery.
[Diagram Description: A cross-section of the E15 valve showing the piston in the open position for full flow. Solenoid S1 is energized, allowing fluid pressure from the inlet to push the piston back, opening the main flow path. Fluid from the back of the piston escapes via a bleed hole to the Air Eliminator.]
Dwell Flow
When making a preset delivery, the system will transition from full flow to dwell flow near the end of delivery. At the point when dwell flow begins, the S1 solenoid valve de-energizes at the same instant the S2 solenoid valve energizes. After the S1 solenoid de-energizes, the piston and compression spring move back into position and close the flow path through the E15 Valve. When the S2 solenoid valve energizes, it opens a flow path for the liquid from the inlet end of the E15 Valve, through the P to A ports of the S2 solenoid valve and to the outlet end of the E15 Valve.
[Diagram Description: A cross-section of the E15 valve showing the piston transitioning to dwell flow. Solenoid S1 de-energizes, allowing the piston to move back and partially close the main flow path. Solenoid S2 energizes, opening a new path (P to A) for controlled flow.]
Air Check Functionality
The A3982 series E15 Valve also acts as an Air Check Valve enabling removal of slugs of air, if introduced prior to the meter. Air is sensed by the Air Eliminator float dropping in a mechanical system or by the optical sensor in an Optical Air Eliminator. During delivery, if air is introduced upstream of the meter, the system pressure from the Air Eliminator passes through the A to B ports of the S1 solenoid valve and is allowed to build pressure on the rear side of the valve piston. The system pressure along with spring pressure is greater than the pressure of the liquid entering the E15 Valve, thus closing the valve. Once the air has been removed by the Air Eliminator, the pressure on the rear side of the valve is bled off through the limited bleed port in the Air Eliminator, allowing the delivery to resume. This ensures utmost accuracy when performing split compartment testing or in case air is introduced upstream of the meter.
