This is an ASCO air operated solenoid valve, it may be unused (it looks that way).  The label says the following:

         Catalog No. P321A3

         Air/Inert Gas PSI 125

         Serial # F662679

         Aux Air 30-125 psi

         Water (PSI) 10-125

         Rebuild Kit 212629

         Pipe 1/4

         Lt Oil (PSI) 10-125

         Date 9701

It looks like this valve was prepared for assembly but was never actually installed in anything - the threads in the two open ports look like nothing has ever been screwed into them - I've left the nice stainless steel fittings on the valve, perhaps you can use them and save some $$.

The ASCO site shows this valve here:

the following information is from that page Page AirOperated_7.07.pdf
Kit umber 212629
Listed in Catalog 33

I believe this will take you to an appropriate spec sheet:

the spec sheet says: "
Unique sealing member isolates pilot air pressure from mainline fluid.
Variations in pilot air pressure do not affect valve operation.
Design provides long life handling of lubricated air.
Handle fluids up to 200F (92C).
Some constructions handle steam up to 353F (177C).
Mountable in any position.


0-60 PSI gauges


NEW, in the box, 2 inch diameter gauges made by Marshall.  The gauges are calibrated in both PSI and KiloPascals.  They include the bracketry and mounting hardware (see picture).  The threads on the attachment fitting are 1/8 NPT (brass).  These gauges are suitable for air, nitrogen, argon, etc.  They fit into a 2 1/8 inch hole if you wish to panel mount them.  The box is marked "G10055", "2.0  23B" , " 0.60.#&KPA  1/8N".

 konan valve

Konan brand solenoid valve

New valve (at least based on my careful inspection, no marring of the threads, etc, I believe it's unused, but terminals have been crimped on the wire ends), no box, has normally open and normally closed ports.  Note that I am not charging a packing or handling fee, will ship by US priority mail within the USA, so shipping will be inexpensive.  The valve has the following features:

24VDC coil, 10 watts (.370 amps) 1/2 NPT conduit fitting for electrical connections Catalog # 5303AH16V3BC9 Stainless steel valve body 100 PSI max, gas, liquid, or oil

Serial number B94IKH

The aluminum label on the valve says "KONAN  Glendale CA, USA"

Paper sticker on valve body says "KONAN Factory Mutual System Approved"

Brooks 1110 series flow meter

This is  a large "FULL-View" glass tube variable area flow meter. The glass tube is enclosed in a heavy duty aluminum and glass enclosure allowing the indicating ball to be seen from front and rear. The scale is calibrated in milimeters, range of 0 to 250 mm.

The model number is 1110-01H1A1A, Serial number 70006-42781

If you look on page 11 of the spec sheet there is a model code chart for
model 1110-1140 Series flow meters under meter size this particular model was a size 7
designated by the letter H in the model #.

unused? 2 inch X 4 threads per inch no-go gauge - I've had it for a long time, I think it came from Douglas Aircraft surplus store in the 60s, but I don't remember. It has the green protectant on the end, as you can see from the picture

Grove Hydraulic Valve, with very large aluminum handle".  Body is steel, 1" thick.  Removed from a hydraulic cylinder test set - presumably aircraft related - very nice valve, 10 turns (maybe 9 - I might have lost count) from stop to stop, designed for precise flow control. I haven't seen this design before - the big handle threads onto the valve body and then presses on the stainless steel stem to control the flow - there is a clip ring to keep you from  unscrewing the handle.  The valve has one inlet and two outlet ports - I presume it is a 3000 PSI valve, though there are no markings on the valve body.  The handle is marked 098001A.

Brooks 8844 NonRisingStem Low flow rate controller valve

Description Brooks NRS flow controllers accurately adjust and maintain small gas and liquid flows. Model 8844 is designed for constant downstream, variable upstream applications and Model 8944 is designed for constant upstream, variable downstream applications. Models 8844 and 8944 are supplied with an integral NRS (non-rising stem) control valve. It features an adjustable sliding tapered needle which resists sticking due to foreign matter in the fluid. Particularly suitable for precise control requirements, this valve possesses a high turns-to- lift ratio which provides stable flow for any given stem position.

Design Features Integral compression fittings, standard Performance tested on Helium Non-rotating needle control valve O-ring seal shutoff on needle valve is bubble tight...cannot be damaged by over tightening Integral needle valve, 15 turns full open to full close, with smooth non-reversing flow characteristics Six interchangeable valve sizes for a wide variety of flow ranges Suitable for panel mounting

This item is in very good, possibly near new condition - as you can see from the photo, it is missing the knob - I believe that it was mounted to a panel on an item of equipment that was surplussed before it was placed into use.

Probe marked WTM 7028

material that follows is from


Welker Probe Regulators provide a regulated sample supply of liquid or gas product from a pipeline to chromatography H2S analyzers, gravitometers, calorimeters and other on-line analyzing equipment.
Two models are available-a Standard Probe Regulator that is designed to be installed in the pipeline,and an Automatic Insertion Probe Regulator that is designed to be inserted into (and withdrawn from) a pressurized pipeline (maximum operating pressure 1800psig) without pipeline shutdown.
On both models, the inlet is positioned on the end of the probe to enable it to collect product from the central portion of the pipeline-giving you a more representative sample. Both probe regulators inhibit carry-over of free liquids into the instrument supply system.
The diaphragm design of the Probe Regulator allows it to respond quickly to sensitive changes in outlet pressure, making it well suited for applications requiring an accurately regulated source (down to 0 psig).
The Automatic Insertion Probe Regulator allows the operator to control the movement of the regulator in and out of the pipeline safely-through the use of three control valves on the oil reservior. This is especially advantageous in applications where it is inconvenient to interrupt the flow in the pipeline.

Click to enlarge  Flow switch that has been sitting in my garage for quite a few years.  Since I've never used it nor needed it, it's time for it to find a new home.  It looks like it's never been used, although there are a few scratches on the outside from knocking around with other stuff - both ends are sealed with plastic plugs, so there should be no contamination inside.  The threads on both sides are, as best I can tell, 1 inch X 13 threads per inch.  There is a directional arrow stamped in the body indicating the direction of flow.

The body is aluminum, I believe, painted gray (it's non magnetic and sure looks like aluminum).  The label reads as follows:

         Gems Co, Inc

         Farmington Conn


         Mfrs P/N 11300

         Mfrs S/N F-1034-M

         Type No. III

         Contr No.   DSA-9-16116

         Stock No. 5930-873-6589

         N.A.A.SPEC  5-11287-8

On the side, it has been stamped "O ring Cure Date: 1Q64   ASSY 1Q65"

So, that makes me think this is a 40 year old valve, probably surplus from the space program, or from aircraft equipment, possibly from the old Douglas Aircraft plant at Clover Field in Santa Monica  (I got it decades ago from a retired machinist near the Douglas Plant).

So, you can have a piece of history, or a useful valve, your choice.  You certainly need this wonderful thing more than I do.  $12.00
