Smooth Operator Pneumatically Driven Three Way Mixing Valve For Reliable Hot Cold Water Regulation In Unitary Fan Coil Units Quick Flare Hookup Abrasion Proof Seals And Low Stress Servicing

Single Pneumatic Three Way Mixing Valve for Fan Coils
✔️ Flared connections 360 rotation sealed composition disc

This single pneumatically operated water valve balances hot and cold supply streams inside unitary fan coil and induction air handlers. It drops right in as a swap piece for legacy Johnson Powers Roberts HAW Barber-Colman and Honeywell assemblies while keeping pipe stress low and sealing tight under constant cycling.

✅ Corrosion resistant metal body stands up to humid coil dampness
✅ Molded in composition discs keep lines leak free when closed
✅ Quick flare hookups save time since no fancy wrenches are needed
✅ Rotating head makes air tube routing a breeze around tight framing

💡 What does a pneumatic mixing valve do in an HVAC fan coil system?

It balances hot and cold water streams using compressed air signals rather than manual handles.
- Handles temp tweaks smooth across steady cooling heating cycles
- Delivers steady pressure drop rates even when coils switch modes fast
- Simplifies shop work since swapping worn cartridges takes minutes flat
- Cuts downtime quick because handy techs can mount new units without pulling pipes ✝️
