How does the E-LO Electric Low Pressure Control Valve Work?

The E-LO is a durable, smart, cost-effective low pressure control valve. In this video, Product Manager Alex Crow demonstrates how the valve works.

How Does It Work?

The E-LO control valve is a low power, low pressure controller, and because it’s made with a standard Kimray body and seat it can flow any media that you normally find in natural gas or oil production.

Inside the E-LO’s cover is the master control board. This is where your module connects. If you want to use a different module, you simply snap the old one out and snap the new one in.

You will also see a 4-pin connector with the Voltage In and Ground on the board itself, as well as a proof-of-closure connection. This is for discrete output to an LED or an auxiliary alarm to let you know it’s seated.

When you initially power up the valve, the motor will drive the seat completely closed, and you’ll get an LED indication of that closure. 

You can also test the actuation of the valve with the button for on/off control.  When the motor is running to open the valve, you will see a green LED indication. And when it closes you will see a red LED indication. It takes about four seconds fully open and two seconds to close.

Control Boards for the E-LO

The E-LO is an electric low pressure control valve designed to control flow in applications less than 45 psi.  It features a modular control board, and we offer three different modules for the board: 

  • a discrete module, which uses dry contacts only, less than three volts
  • an analog module, which is 4-20 milliamps for variable control
  • a Modbus control module for Modbus RS-485

Coming soon, we also have an RTD module for use with a PT 100 3-wire RTD.

Applications for the E-LO

The E-LO can be used as a dump valve, a burner control valve, or for any type of flow control under 45 psi.
