View all productsWhen the day runs hot and the jobs stack up, your gauges can’t slow you down. This 4-valve digital range is built for Australian conditions—bright, easy-read screens, rugged housings, and smart layouts that let you pull a deep vacuum and charge cleanly without constant hose juggling. It’s the kind of kit that makes long days shorter and results more consistent.
Why do you want to use a 4-Valve Digital Manifold?
- Dedicated ports: Low, High, Vacuum, and Charge/Recovery—workflows stay connected while you isolate what you need.
- Faster evacuation: Keep the pump on the vacuum port and pull down without breaking connections or risking contamination.
- Clean charging: Add refrigerant through a dedicated path, reducing moisture ingress and saving time between steps.
- Smarter readings: Live pressure/temperature with calc’d superheat/subcool so you can tune systems accurately in the field.
Who Benefits Most
Ideal for techs working across domestic and light-commercial systems who want repeatable accuracy and quicker job turnover. If you’re chasing fewer callbacks and cleaner workflows on R32, R410A, R134a or mixed estates, a 4-valve digital is a genuine step up.

4-Valve vs 2-Valve: What’s the Difference?
| Feature | 4-Valve Digital | 2-Valve (Analog/Digital) |
|---|---|---|
| Ports & Flow | Low, High, dedicated Vacuum + Charge/Recovery. Minimal hose swaps. | Low & High only. Share ports for vacuum/charge; more hose changes. |
| Evacuation Speed | Typically faster—pump stays connected; better isolation & flow path. | Adequate for quick jobs; slower when breaking connections between steps. |
| Charging Workflow | Charge through a dedicated valve—clean, controlled, fewer contaminants. | Charge via shared ports; more chance of air ingress during changeovers. |
| Best Use Case | Frequent installs/commissioning, light-commercial, busy domestic with tight schedules. | Quick diagnostics, occasional charge/repair, lighter domestic service. |
| Learning Curve | Slightly more to set up; pays off with speed and repeatability. | Simple and familiar; fewer valves to manage. |
| Value Over a Season | Higher upfront; time saved on every job compounds fast. | Lower entry cost; fine for occasional use or smaller workloads. |
Accuracy You Can Trust
Stable sensors and clear, backlit displays make it easier to hit target SH/SC even in bright sun or plant-room gloom.
