Mechanical V-Series Valves

V-7 Preset valves are designed to function with a mechanical preset to shut down the flow after a predetermined amount of product is delivered. The preset allows this valve to be mechanically shut down in a single stage or in two-stages. Single stage shut downs are generally utilized with slower flow rates or with more viscous products where hydraulic shock is less of an issue. A two-stage shutdown allows for a slowing of the flow rate before the final positive shutdown, thus avoiding hydraulic shock.

Differential Valves

Differential/Air Check valves are placed on the outlet side of a meter system and work in conjunction with the system’s air/vapor eliminator to stop the flow of product through the meter until the air/vapor is eliminated. In order to do this, the air/vapor eliminator and the valve are piped together at installation. Differential/Air Check valves are normally closed, but when the pump starts and pushes product into the system, the valve spring will give way to the flow pressure. In order to keep the valve closed when air/vapor is being expelled from the air/vapor eliminator, the air/vapor from the air/vapor eliminator is routed through the piping to the back side of the valve spring. The combined force of the expelled air/vapor and the strength of the spring keep the valve closed until the air/vapor is eliminated.
Materials of Construction:
 • Aluminum
 • Standard 2″ aluminum valve is spring loaded and designed to fail closed.
 • Provides a constant 15 PSI differential pressure and controls flow when vapor is sensed.
 • The 511-series differential valve is available with an adjustable differential pressure setting of 5 to 16 PSI.
 • Available in ductile iron or cast steel in sizes of 2″, 3″, 4″ or 6″ flanges.
 • Typically used with our MS-series meters and accessories.

Optical Air Eliminators

Optical air eliminators detect changes in refractive index to detect air. An optical air eliminator is more responsive than our mechanical air eliminator and less product ends up in your external catch tank.
The Liquid Controls Optical Air Eliminator is designed for use with LCR.iQ, LCR-II, or LCR 600 Electronic Registers.
Features:
 • Provides for the efficient elimination of air and vapor with virtually no moving parts
 • An optical sensor is used to monitor the liquid level
 • The presence or absence of liquid at the sensor level activates or deactivates a solenoid located at the top of the air eliminator. The Optical Air Eliminator requires the use of a solenoid operated valve.

When liquid rises to the optical sensor level, the solenoid closes and prevents continued venting to atmospheric pressure, and the electronic control valve at the meter outlet opens so that a delivery may continue. This functionality ensures that only liquid passes through the meter.
The optical air eliminator is designed to work with Liquid Controls meters for applications measuring refined petroleum products and LPG.

Specifications:
 • Materials of construction: Aluminum
 • Environmental Rating: NEMA 4X
 • Safety: Designed to meet Class I, Division 2 requirements
 • Temperature Rating: -40° to 160°F (-40° to 71°C)
 • Maximum Non-Shock Working Pressure
    • 150 PSI (10.3 BAR)
    • 350 PSI (24 BAR)
 • Maximum Differential Pressure: 100 PSI (6.9 BAR)
 • Solenoids Voltage: +10.2 to 13.6 VDC (Optional Voltage: +20.2 to 27.2 VDC)

Steel Air Eliminators

Liquid Controls mechanical air and vapor eliminators remove air and vapor from metering systems. Removing the air and vapor from a metering system increases the accuracy of the meter by allowing only liquid to pass through the meter.

At installation, LC mechanical air and vapor eliminators are piped to a storage tank to provide a pathway and a receptacle where the evacuated air vapor can be deposited. After the air (or vapor) has left the metering system, mechanical air and vapor eliminators seal off the pathway to prevent liquid from entering the storage tank. Features:
 • For use MSA and MSAA Series Steel case Meters
 • Materials of construction for Classes 1, 10, 14, and 16 applications
 • For installation on FS and FSA Series Steel Strainers
 • All steel air eliminators are rated 350PSI

Bulk Plant Air Eliminators

At installation, LC mechanical air and vapor eliminators are piped to a storage tank to provide a pathway and a receptacle where the evacuated air and vapor can be deposited. After the air (or vapor) has left the metering system, mechanical air and vapor eliminators seal off the pathway to prevent liquid from entering the storage tank.

Now available with an optical sensor, the Single Head Bulk Plant Air Eliminators — provide a new bulk plant air elimination solution that simplifies installations, reduces maintenance, and removes problematic slugs of air. The Single Head Bulk Plant Air Eliminator with Optical Sensor marks the latest breakthrough in the four-decade long evolution of Liquid Controls’ air eliminators. It is ideal for eliminating air from refined fuels applications where product is metered into storage from a truck-mounted pump.

The optical sensor provides the same functionality of the dual head mechanical air eliminator in a single head design. The optical sensor, when used with an electronic register provides a signal to a downstream control valve to shut down in the presence of a large volume of air. This prevents the air from being metered. The high mount air eliminator evacuates the air until the optical sensor does not sense the air. In the presence of liquid, the valve now opens and the product flows through the meter.

Features and Specifications:
 • For use in any 150 PSI working pressure system using aluminum M-Series or steel MS-Series Meters.
 • Choice of 3", 4", 6" and 8" ANSI flanged connections.
 • Shown is the dual head mechanical model providing twice the normal venting capacity.
 • Dual head model is most effective when utilizing a differential valve.
