The UV-4R Control valve is used for residential and LULA applications.
The UV-5 Series commercial control valves are equipped with full Temperature Compensation over their entire operational ranges. The UV-5AT is capable of handling flow rates of 20 (76 lpm) to 200 (757 lpm) gpm. The UV-5AT can be identified by the gold flange on the front of the valve.
The optional UV-5ATC also offers Pressure Compensation for constant down speed control. This modification of the down piston assembly delivers constant down speed between no-load and full-load conditions. It can be identified by the blue flange on the front of the valve.
The UV-5BT Valve functions the same as the UV-5AT but the Return Port is at the bottom. This valve requires less space in the tank. It is available standard with Temperature Compensation (Gold Flange) or the UV-5BTC which has Pressure Compensation (Blue Flange) for constant down speed control.
The UV-7B hydraulic control valve performs all the necessary functions for the operation of a hydraulic elevator in both directions of travel. The UV-7B is the ideal solution for low pressure, high flow rate applications. The UV-7B is capable of handling flow rates of 150 (568 lpm) to 400 (1514 lpm) gpm.
The optional UV-7BC also offers Pressure Compensation for constant down speed control. This modification of the down piston assembly delivers constant down speed between no-load and full-load conditions.
Please refer to the image above. This image shows a typical EECO Control Valve Serial Number. It contains information about the valve size, valve series, the date of manufacture and the individual valve sequential number.
1st character= size: 1 (3 gpm up to 20 gpm), OR, 2 (up to 35 gpm)
2nd character= identifying series number which is “R”
3rd and 4th characters= year of manufacture
5th character= month of manufacture (1 to 9 and October-O, November-N and December- D)
6th thru 9th characters= actual series number 0000 (starting number will be the quantity of all valves manufactured by Gale from the beginning up to 10/31/2016 +1)
10th character= blank for standard valves or letter “L” to identify if the valve is in a low working pressure (below 200 psi) application
