Beer Heads - Types and Features
The beer head, once connected to the barrel valve spout, is the element that allows the entry of CO gas(COtwo), mixed gas NNtwo) or air in the kegs and makes the beer rise up to the beer dispensing taps. The stainless steel heads due to their characteristics and features are the most widely used in the Spanish market, they have a safety mechanism that prevents CO outputtwo when the head is not connected with the sprat.
There are different models with a body made of tin-plated brass or stainless steel, but all the models have in common that all the parts in contact with the beer are made of stainless steel. Not all brands of draft beer use the same type of valve on the keg. Each different "system" requires matching the proper head to the barrel valve.Micro Matic shows us a table where each type of head and barrel system is specified according to the best-known brands.
Incorporate twovalves anti-return for optimal operation of the dispensing system:
- CO valvetwo that prevents the return of beer through the gas pipe.
- Beer valve whose mission is to prevent beer leaks by disconnecting the heads of the kegs.
Themain features of these types of heads are:
- They incorporate two non-return valves, one for beer and one for gas.
- Surfaces with high quality finishes. Very durable and easy to use.
- Careful design thought to avoid the accumulation of dirt.
- Multiple connections for both beer and COtwo. Fast connections(John Guest) or spike type.
- EPDM gaskets suitable for food use.
- Simple disassembly for cleaning or maintenance.
Head A is a circular flange, very commonly used by German brewers, it is known as the German slider, since it slides on the valve face. The quintessential head of wheat beers, used by the Hoegaarden, Paulaner, Spaten, Warsteiner and Weihenstephaner breweries. Connects to the sprat by lateral / horizontal displacement.
The D head is designed to work with American or American Sankey sprats. It is the most common system available in the US. Available with 2 ergots. Used by major American breweries: Anheuser Busch, Miller, Molson Coors, and Labatt, as well as most American craft breweries. The connection of the head with the sprat is made by slightly turning the head until it stops.ope.
The G head is the trilobular flange, widely used in Spain by large brewers. This system owes its name to the English developer, Grundy. The valve face can be thought of as a circle with three cut sides. Used by Bass, Boddingtons, Caffrey, Anchor Steam and Damm breweries. The connection of the head with the sprat is made by slightly turning the head until it stops.
The L head is a circular flange and is primarily used for carbonated soft drink dispensers. It is the least known and used type of head. Connects to the sprat using a Lateral / Horizontal displacement.
Micro Matic's M head is circular flange and designed to work with M sprats. It was recently introduced to the US market. The body is the same as the German slider, but the probe configuration is unique. Used by the Schneider, Aventinus and Einbecker breweries, it is connected to the sprat by lateral / horizontal displacement.
The S head is designed to work with well-type or Sankey sprats, widely used in Spain by large brewers. Available with 2 or 3 ergots linkers. Many European breweries use this system, also known as the European Sankey. Distinguished by being longer than Type D or American Sankey. Used by Heineken, Becks, Amstel, Pilsner Urquell, San Miguel and Cruzcampo breweries. The connection of the head with the sprat is made by slightly turning the head until it stops.e.
Head U is similar to head S, not being interchangeable. The use of this head in Spain is infrequent, being the Guinness brand practically the only one that uses it. This system takes its name from the UEC, made in England. The connection of the head with the sprat is made by slightly turning the head until it stops.
Ball lock head for Cornelius type barrels. It consists of a black beer outlet head and a white gas inlet barrel head. Both connectors have a molded socket nozzle for the barrel valve. No need for wrenches to connect the barbed connector, just make the socket kit. It is the head par excellence used by Homebrewers thanks to its easy cleaning and assembly. To the gas head it is necessary to incorporate a non-return valve since it does not have it and could cause damage to the pressure reducer or compressor due to the entry of beer into the equipment.ipo.
Cornelius barrel heads have two varieties that have the same use and function: pin-lock and ball-lock, and are not interchangeable. Historically, pin-lock barrels were primarily used by Coca-Cola, while ball-lock barrels were primarily used by Pepsi. In a pin-lock barrel, there are metal stud bolts that extend horizontally around the valve. When the head is attached, these pins stay in place. The "gas-in" valve has two pins, while the "liquid-out" has three, making it impossible to accidentally place the inverted heads which would result in carbon dioxide bubbling through the beverage, but no beverage coming out . Ball-lock barrels have ridges on the ports, which are held by small metal balls on the connectors.res.
Twin Probe Twin Probe Head - Hoff-Stevensns
Stainless steel head with dual probe system that is no longer in use by any major brewery. It is of limited use by some American craft breweries. It has a system similar to Cornelius Ball-Lock head, one valve introduces the gas and the other withdraws the beer.
