John Guest Drinks Acetal Valves

John Guest acetal push fit valves are widely used in pubs, bars and commercial beverage installations to control the flow of liquids and gases within drinks dispense systems. These valves connect directly to drinks dispense tubing using push fit technology, allowing installers to create reliable connections quickly without the need for tools.

Commonly used within beer dispense systems, beverage equipment and water supply installations, push fit valves provide a convenient way to isolate equipment, control flow and prevent backflow. They are frequently installed in pub cellar systems, coffee machine water lines, beverage dispensers and filtration setups where reliable control of the fluid supply is essential. Designed to work with compatible tubing such as LLDPE drinks dispense tubing, these valves form part of a complete push fit system alongside fittings and accessories.

Acetal push fit valves are inline valves designed to connect directly to plastic tubing using push fit connections. The valve body incorporates the same push fit mechanism used in John Guest fittings, allowing tubing to be inserted quickly and securely.

Once installed, the valve allows operators or installers to control the movement of liquid or gas through the system. Depending on the valve type, it may be used to stop flow completely, isolate equipment during maintenance or prevent reverse flow. These valves are commonly installed in:

• Beer dispense systems in pubs and bars
• Beverage lines supplying soft drink dispensers
• Water supply lines feeding coffee machines
• Vending machine water feeds
• Filtration and reverse osmosis systems
• Gas supply lines for keg systems

The durable acetal construction provides a strong, corrosion resistant valve body suitable for use in beverage installations.

One of the key advantages of push fit valves is their simple installation process. Because they use push fit connectors, the valves can be installed quickly without specialist tools. A typical installation process includes:

1. Cut the tubing square using a pipe cutter.
2. Ensure the tubing is clean and free from damage. If damaged or deformed, a tube insert can be used.
3. Push the tubing fully into the valve until it reaches the internal stop.
4. Pull gently on the tubing to confirm the connection is secure.

The internal collet grips the tubing while the sealing element creates a leak tight connection. Because the valve uses push fit connectors on both sides, it can be easily installed within an existing tubing run. This simple installation method makes push fit valves particularly suitable for pub cellar installations, beverage equipment servicing and drinks dispense system upgrades.

Push fit valves are used throughout commercial drinks dispense systems where control of fluid or gas flow is required. Common applications include:

• Isolating water supply lines to coffee machines
• Controlling beverage lines in dispense equipment
• Preventing backflow in water filtration systems
• Isolating gas lines within keg systems
• Maintaining drinks dispense equipment

Because drinks dispense systems often contain multiple pieces of equipment connected to the same supply line, installing valves allows individual components to be serviced without disrupting the entire system.

Push fit valves are designed to work alongside other John Guest drinks dispense components.

• LLDPE Tubing

  • Valves connect directly to LLDPE tubing, which is commonly used for beer lines, water supply lines and gas feeds within beverage systems.
• Grey Acetal Push Fit Fittings

  • Push fit fittings are used throughout the system to join tubing and connect equipment. These fittings work alongside valves to build a complete dispense installation.
• Drinks Dispense Accessories
  • Accessories such as locking clips, tube inserts and strain relief components help ensure the system remains secure and easy to maintain.

Together, tubing, fittings, valves, and accessories form a complete push fit drinks dispense system.

Can push fit valves be used in drinks dispense systems?

Yes. Push fit valves are widely used in beverage installations, including beer dispense systems, water filtration systems and beverage equipment. They are particularly useful because they allow tubing connections to be made quickly without tools.

What size push fit valves are commonly used?

Can push fit valves be reused?

Yes. Push fit valves are demountable, meaning the tubing can be removed by pressing the collet and pulling the tubing free. This allows systems to be modified or repaired without replacing the valve.
