SIGHT GAUGES
Click Here To View Our Product Data Sheet
“Liquid level Gauge”:
Used to calibrate chemical injection systems. The gauge provides a visual means for checking the contents of a bulk tank and a means for checking the injection rate of a chemical metering pump. To gauge is designed to operate in low to medium pressure applications up to 500 psig.
One Minute Test:
Isolate the chemical in the tank from the gauge. The scale on the left side is for the gauge volume and the scale on the right will read the flow rate of the pump; i.e. gallon per Hour (GPH). Keeping the
isolation valve closed and noting the number of marks the fluid
passes in one minute will give the actual chemical pump rate.
Gauge Features:
- Teflon compression ferrule used to isolate the glass tube from the chamber
- Rugged armored gauge construction protects sight glass from mechanical impact
- Custom scales for tank volume or other calibrations are available
- Armored frame and poly carbonate shield protect operator
- ½” NPT and flange connections standard
- Standard sight tube is 5/8” O.D. glass.
- Made in the USA
Gauge Specifications:
- Process Connection: ½” MNPT

• Made in the USA
BACK PRESSURE VALVES
Click Here To See Our Product Data Sheet
Back pressure valves using diaphragms are designed to protect pumping systems from over pressure damage caused by defective equipment or blockage in the pump system line.
Eddington Industries is a manufacturer of high quality back pressure valves made from a variety of different materials to suit most needs. In most cases we are able to ship within 2 – 3 days after receipt of order because of our extensive inventory.
FEATURES OF EDDINGTON BACK PRESSURE VALVES:
- Reliability and low cost.
- Adjustable from 15 to 150 psi.
- 2 port (standard) or 3 port (with gauge).
- Viton diaphragm standard (others available).
- Full range of chemically resistant wetted materials.
- Sizes from ¼” to 1” depending on model.
Diaphragm back pressure valves operate when the pressure in the pumping system exceeds the preset pressure of the valve. The diaphragm is held against the valve seat by an internal spring. When the preset pressure is exceeded the diaphragm is forced up and the system fluid flows out the relief port, back to the system fluid tank or to the suction side of the pump. The valves are pre-set at 40 psi; however they are field adjustable from 10 to 150 psi, (optional 350 psi) via the adjustment screw. The relief valve should be set approximately 15 psi higher than the system pressure. Installation should be made as close to the pump as possible.
Eddington Industries performs a pressure test on every back pressure relief valve prior to shipping.
This ensures the unit will operate leak-free and to the specified pressure ratings.
These Eddington Industries back pressure valves come standard without a gauge port or gauge. When ordering please specify if a gauge port and/or gauge is required.
PRESSURE RANGE:
5 – 150 psi (50 – 350 psi available on metal valves).
AVAILABLE DIAPHRAGM MATERIAL:
Viton – Standard.
EPDM – Upon Request.
