Identifying a valve
I need to identify the make and model of one of my control valves. The bleeder pin has come completely out and got lost. So I need to buy a similar valve so I can swap in the bleeder pin from the new valve.
It's a black inline valve with no flow control. The housing has a flat top divided into (I think) eight sections. The bleeder pin is exactly in the center of the flat top. The solenoid assembly is to one side, next to where one of the pipes is clamped onto the valve (I presume this is the downstream side of the valve). I'm not able to see any make, model, or any other identifying markings.
The system was installed when the house was built in 1984. This gives some idea of the vintage of the components.
Does anyone have any idea what make and model this valve might be? Thanks in advance for your help.
