What is a beer keg spear accessories?
International standards define beer keg spear accessories as beer keg discharge valves. They are replacement spare parts in the entire valve set and are the core components for the beer pressure keg to achieve air intake, preservation, wine dispensing and pressure relief. Its working logic is to use a distributor to connect the channels on both sides of the barrel behind the winegrass, so that CO2 enters the barrel to pressurize it. The equipped seal is responsible for self-sealing and maintaining pressure to prevent the wine from oxidizing and deteriorating.
Product advantages
Food-grade material
The main metal parts of valve accessories are generally made of SUS304 austenitic stainless steel, and the seals are made of food-grade EPDM rubber. Both standards meet the requirements of American food contact materials, so it will not emit odor or react with the wine body. The state is very stable, so the flavor of the wine body can be guaranteed.
Safe pressure relief and explosion-proof structure
The wine barrel has a built-in CO₂ valve that can be controlled at any time. When the alcohol is over-pressured, the rubber valve can release the alcohol gas in an orderly manner to avoid safety accidents caused by excessive pressure in the barrel.
Easy-to-clean design
We optimize the structure of the product chuck and locking plate, and eliminate closed and flat dead corners to reduce the accumulation of yeast and wine residue and the breeding of bacteria. Therefore, it is highly hygienic and convenient to clean, prevents the formation of bacteria and extends the service life to a certain extent.
EPDM sealing is stable
EPDM is ethylene propylene diene rubber. This material has excellent aging resistance and ozone resistance due to the high saturation of its molecular main chain. It also has a wide operating temperature (-50℃~+150℃) and can perform well under any usage conditions to achieve stable sealing.
Usage scenarios of standard parts of beer keg spear accessories

Usage scenarios |
Scene description |
Matching valve accessories |
|
Craft winery barrel cycle maintenance |
The winery turns over large quantities of stainless steel beer barrels, and the barrels are cleaned and inspected before filling each time. Therefore, wearing parts need to be replaced regularly to ensure stable filling and pressure maintenance. |
CO₂ intake valve core, O-ring, return spring, locking plate, etc. |
|
Beer systems for bars, restaurants and beer walls |
When beer machines, beer walls, and draft beer dispensers in offline stores are connected to wine barrels, air leakage, pressure loss, bubbling, and flow interruptions may occur. |
Sealing gasket, pressure relief valve core, spear tube, etc. |
|
Wine barrel turnover service provider |
After the wine barrels are rented and recycled, they will be refurbished and inspected uniformly, and general standard accessories will be stocked. |
Seals, springs, valve cores, etc. |
|
Homebrewing workshops and small-scale craft brewing operations |
Small pressure beer kegs, draft beer kegs and home-brew filling all need to be stored under pressure. |
O-ring, intake valve core, etc. |
7 kinds of small parts composition structure
Beer keg spear accessories are composed of multiple independent functional parts. The following is an introduction to each component part:
1.CO₂ intake valve: This is the core sealing and pressure relief component. It mainly controls the entry of carbon dioxide into the barrel and realizes the function of automatic pressure relief after overpressure.
2. O-type sealing ring or flat gasket: This is an EPDM material seal, used to seal between the barrel neck and the valve body to prevent gas and wine leakage.
3. Stainless steel spring: The purpose is to provide rebound force to keep the valve normally closed. After the distributor is connected, press down to open the gas-liquid passage.
4. Locking piece and limit pressure plate: mainly fix the position of the spring and valve core, while leaving a gap for water flow to facilitate cleaning
5. Valve body: The main body is a stainless steel base with standard threads, which locks with the neck of the beer barrel.
6. Spear tube: a long stainless steel straight tube, the purpose is to extend to the bottom of the barrel, so that the pressure in the barrel pushes the wine liquid to flow upward along the spear tube
7. Safety lock (optional): This is an anti-accidental disassembly structure that can improve the commercial safety level
Maintenance and installation
Installation points: Before installation, you need to clean the neck threads and old seal residue in the beer barrel. It is necessary to use a torque wrench to tighten according to the torque to prevent air leakage after being too loose. It should also be noted that the assembly sequence of the valve core cannot be reversed.
Maintenance cycle: Shata recommends a maintenance cycle of 7-8 years for the entire wine spear machine. Wearing parts such as seals and rubber valve cores are recommended to be inspected and replaced every 1-2 years.
Cleaning method: The beer keg spear accessories support CIP cleaning fluid to be directly passed into the inside of the kettle and spear tube to clean and flush the passage. There is no need to disassemble and assemble the kettle, and it must be fully drained and dried after cleaning.
Fault diagnosis: If your wine barrel has unstable wine dispensing, continuous air leakage, or pressure-maintaining failure, you need to give priority to replacing the CO₂ valve and sealing ring. If it still fails after inspection, please contact us in time.
Cleaning method
The cleaning method of beer keg spear accessories is also very important. We have listed the most common usage scenarios and cleaning steps. You can check them by yourself. This is the most critical step to ensure the service life.

Cleaning Method |
Applicable scenarios | Cleaning steps |
|
Commercial CIP cycle cleaning |
Used by craft breweries and large barrel merchants |
1.Release the pressure, disassemble the wine spear, and put the parts into the CIP circuit 2.Pre-flush with hot water to rinse away the wine residue 3.Alkali circulation, mainly to remove protein and yeast organic matter 4.Rinse with water until pH is neutral 5.Acid circulation, mainly to remove beer stones Drain after rinsing and disinfecting |
|
Manual soaking and scrubbing |
Bars, restaurants, small home breweries |
.1. Completely relieve pressure and disassemble all parts: valve core, O-ring, spring, locking plate, spear tube, etc. 2. Pre-rinse with warm water at 40–50℃ 3. Soak in detergent for 15–20 minutes 4. Use a soft nylon brush to clean the gaps, threads and inner wall of the spear tube 5. Rinse off residual chemicals with clean water 6. Store away from light after natural air drying. |
|
Easy rinse |
Quick maintenance of bars and pubs between business hours |
1.Relieve pressure after disconnecting CO₂ 2.The distributor is connected to the warm water circulation flushing lance tube passage 3.Circulate the cleaning agent for a short period of time and rinse with clean water. 4. Blow dry |
