Lancer 24V 1-Valve Push Button Island Base Tower - 85-3131-101
Is the 301 Push-Button the right dispenser for your build?
The 301 PB is single-valve, push-button — crew-served single-flavor pours. The self-serve LEV variant exists too. If you need 2+ flavors or self-serve, we'll route you. Answer 3 questions.
1. What's the situation?
2. How many flavors do you need on tap?
3. Who pulls the drink — customer or staff?
4. About how many pours per day at peak?
2. What dispenser are you replacing?
3. Why are you replacing it?
Build the complete 1-valve install in one click
The 301 PB is the tower head — sized for a counter cold plate or ice well. To pour you also need a CO₂ supply, regulator, carbonator (for soda), BIB rack, syrup pump, water filter, backflow preventer, and tubing. Uncheck what you already have. If you're running a plain water station, skip the carbonator and the syrup pump.
Complete 301 PB install bundle (1-valve)
Required + recommended components per Lancer's install guide. The 301 chills via external cold plate or ice bath — your existing bar setup typically has this.

Four things you connect, no internal cooling
The 301 PB is a single-valve tower — sits on top of a counter cold plate or in an ice bath. Same chassis as the self-serve sister; the only difference is the actuator (push-button instead of LEV lever). Water, CO₂, syrup, and power come in from below.
- 1Water in1/4" line at 40+ PSI flowing. Filtered through the BEV135 → carbonator (if soda) → tower.
- 2CO₂ in (soda only)From the 20 lb tank → primary regulator → carbonator → tower at 70–80 PSIG. Skip if you're running plain water or non-carbonated juice.
- 3Syrup in × 1One Bevlex line from the BIB, pulled by a single Flojet pump at 55–65 PSI. One pump per tap. Skip if it's a water-only station.
- 4Cold plate or ice bath (external)The 301 has no internal cooling — it relies on the bar's existing counter cold plate or a flooded ice well. Line pre-chills before it reaches the valve.
- 5Power24V via the included transformer (plugs into a standard 115V receptacle).
