I believe it is a THE valve. reliable used it on some of the omega controllers

Always loved the name...THE valve "what kind of valve do you have?" "THE valve" "I know its the valve, what kind is it?" "THE" "yes I know its the valve, what brand is it"

Ah the old Who's on First!!!!!

Was "THE" a Brand or model? and is it still supported?

i think it is a brand, not sure, i found a manual for a THE valve that has 4 valve coils, but not the one that has 3 I remember we would try to replace that valve as we could. it was not very reliable. looks like yours is still kicking though.

Its still running, I just had never seen one before and my company is looking at taking it on service. It looks like it wouldn't be to hard to convert it to a Maxton.

The piping is the easy part the signals to the valve are where things can get interesting depends on the controller.

Technology Hydraulic Engineering (THE Valve).
Out of Business now, some of the principals went back to Maxton. (Pretty darn good valve.)
The controller that went with it and associated DL1 DL2 Relays should probably be replaced. See circular Letters Below

The customer got their moneys worth out of the ice cube relays. Risky to continue its use past the 10 year mark.

Very good find Robert. Thanks for posting those links!

Looks like a unit out of Europe that Leistrizt used to supply on their power units. Very tempremental with temperature,
