Manual Flow Profiling

Installation Manual

With the Quick Mill E61 Group Head Flow Control Device you can manually profile your extractions by adjusting the flow from the closed position (0-bar) to full pump pressure, usually 9-bar. This E61 flow control device can work on many common machines like the ECM flow control device does.

The flow control device can be installed in machines that are equipped with standard E61 group heads. With just a couple of tools, your coffee machine will be able to vary the amount of flow using the stainless steel needle valve now installed on your E61 group. This needle valve is the main working component that allows the user to vary the flow of water to your coffee where you’ll have full control of saturation and extraction of all that you love about your espresso!

The Flow Control Kit replaces the E61 spring with a stiffer one that does not compress unless manually activated to drain excess pressure through the exhaust. This is so that you do not have to manually manage the pressure of controlling the flow restriction while simultaneously compensating for the pressure difference as that pre-infusion valve compresses.

Installing the E61 Flow Control

The Quick Mill flow control kit provides you with all of the necessary pieces you’ll need to install it to your existing E61 group. It installs on the front of the group with just a couple of tools required:

  • Teflon Tape
  • Electrical Tape
  • 5mm Allen Key
  • 12” Adjustable Socket Wrench

When installing your new gauge, we recommend that you very gently screw in the gauge just until it is barely finger tight. Then unscrew it until the gauge is upright. Then unscrew it, counting the number of rotations you go through. From there, wrap the male threads of the gauge with teflon tape and tighten it back in that same number of turns. That way it will both be in the position you want, and also seal so that it does not leak.

If you have any questions or concerns, please do not hesitate to call or email our service technicians during business hours (Monday-Friday 8am-5pm EST) at 518-452-5995 or email [email protected]

Once you have gathered all the necessary tools required for installation, just follow these easy steps.

  1. Wrap the top of the mushroom with electrical tape to prevent it from getting marred by the 12” adjustable socket wrench.
  2. Loosen the mushroom at the top of the group with the adjustable wrench.
  3. Remove the mushroom from the top of the group, along with the Teflon seal and set aside.
  4. Grab the new mushroom that came with the Quick Mill E61 flow control kit and unscrew the black knob. Now remove the knob and cap before inserting the mushroom into the top of the group.
  5. Replace the Teflon seal that was removed in step three with the new seal that was included with your flow control kit. Install the new mushroom and tighten.
  6. With your hand, turn the post that has been exposed after removing the black knob and cap clockwise until hand tight. This is ensuring that the needle valve is completely closed in this position or ‘off’ as we’ll refer to it.
  7. Now that the valve is in the closed position, set the cap with the black knob attached back on the post you just tightened. Once placed on the post tighten the black knob. This will maintain the position of the cap so as you start to adjust flow the cap does not move positions.
  8. With the 5mm Allen wrench unscrew the Allen screw on the front-center of your E61 group.
  9. Remove the Teflon seal and install it on the backside of the gauge.
  10. Wrap Teflon tape around the threads below the Teflon seal a couple of times and finger tighten the pressure gauge on the front of the group to lock it into place.
  11. Wrap electrical tape around your discharge spout and loosen the nut closest to the top of the spout until removed.
  12. Once the discharge spout has been removed, remove the preinfusion valve. Replace the brew valve spring that surrounds the preinfusion valve with the spring that was included in the E61 Group Head Flow Control Device Kit.
  13. Once the brew valve spring has been replaced around the preinfusion valve and inserted back into the discharge spout, tighten the discharge spout back into the bottom of your E61 group, and you’re ready to start up your espresso machine!

If your dog loves tennis balls, you NEED these
Color: Azure+Orange, Color: Azure+Orange
Raising any puppy is tough. Raising a German Shepherd puppy has often left me questioning my life choices. So I was ecstatic the day that my 60-lb puppy decided that he loves tennis balls and occupied himself for 2 hours without needing constant intervention. Naturally, my immediate response was to make sure we had a constant supply of large tennis balls for dogs available. Now my puppy loves mischief, but he’s not an aggressive chewer. And I was irritated to discover that every brand and size of tennis ball broke within an hour max of play. By simply playing fetch and batting the ball around with his paws, every single tennis ball split into 2 halves. We needed something better! These squeaky balls are exactly that! They come in a 2-pack. I gave my pup the 1st one a week ago and it’s still going strong! We play fetch in the backyard, he brings it into the doggy pool with him, it rolls around in the dirt and can be rinsed off easily. It’s by far his favorite toy, and he takes it everywhere with him. Finally a squeaky ball that can keep up with my dog! These are the perfect size, texture, bounce, squeak, everything. These are the ONLY squeaky balls I will buy from now on. Five stars for sure!

Really are indestructible. Amazing product.
Color: Blue+Red
Wow! Really indestructible. Our large dogs have destroyed other “indestructible” toys in less than an hour and these are amazing. They squeak, which our dogs love (we hate) and they float when they go into our pool. IF they ever do wear out or are lost I will definitely buy again.

Durable squeaky ball for chewers
Color: Blue+Red, Color: Blue+Red
These are great! My 54 lb GSP loves them and it’s the only thing she cannot destroy! She’s currently 1 year and we have had the balls for several months. We have this brand and similar ones too. They float, bounce, and squeak. The ridges are good for chewing.

Finally a Toy My Pitbull Hasn’t Destroyed in 5 Minutes
Color: Blue+Red, Color: Blue+Red
I have a 65 lb pitbull who destroys most toys almost immediately, so I’m always skeptical when products claim to be “indestructible.” Most toys last maybe a few minutes in my house before pieces are everywhere. These have actually held up surprisingly well. The material feels durable and thick enough to handle really aggressive chewing, and so far my dog hasn’t been able to destroy them like he does with most other balls and squeaky toys. That alone makes these worth it to me. I also really like the size. They’re large enough that I don’t have to constantly worry about him accidentally swallowing them or choking while playing, which is a huge plus for bigger dogs. The squeaker inside also keeps him interested longer since he usually gets bored quickly with toys that don’t make noise or bounce around well. If you have a strong chewer or larger dog and you’re tired of replacing destroyed toys constantly, these are definitely worth trying.
