When I decided to ramp up my maple syrup production my wife insisted that I come into compliance with the regulations for the handling of maple syrup which meant that my entire production path needed to be plastic, stainless steel, or ceramic. I had been using a Watts 350C brass pressure relief valve with my first homemade RO system.
This valve replaced the ball valve that I spent hours watching and feathering to try to maintain a steady back pressure in my RO elements.
Being able to simply dial in the back pressure that you want is AWESOME!
When I went looking for stainless steel valves I ended up putting out a call for offers on Alibaba. A really nice sales person named Grain contacted and after some back and forth recommended these valves. I have been SUPER happy with how the one I have been using has been working.
This year I’m moving away from four 400GPD elements to a single 2600 GPD element in a stainless steel 4040 housing. I’m planning to get the stainless steel nipples and fittings that I need to get it hooked up tomorrow in Ottawa. I need to remember to add Ts for a pressure gauge and a pressure transducer.
More pictures to follow.
mmmmmMaple!
I love me a good fluid delivery system. I personally I do alot of hydraulics. But you tree thumpers got some wild shit going on.
Got a good hydraulic shop in ottawa area?
There’s a hydraulic place in Smiths Falls. I’m actually on the McMaster Carr website right now making up an order. I might order from Granger instead because they always throw an Atomic Fireball into the box.
Wait until you see the home made controller that runs the whole system.
I’m spoiled here in the hammer I got hydraulic shops, tubing suppliers, and fluid power suppliers galore.
I like McMaster Carr but damn they have a premium price and a Soviet style approach to their products. No brand choice. You get what you get, brands be dammed.
McMaster Carr is not inexpensive, that’s sure, but they have everything I need and normally deliver the next day if I order before 4 PM. I don’t normally buy from them but there are times where the length of time that it takes me to source something and have it delievered is outweighed by the convenience of just ordering something and having it delievered to my door the next day.
