EMERSON TRAE+9 13 14 22 30 40 45 50MC R134A R401A Expansion Valve 9Ton – 50 Tons

This is Emerson balanced‑port bi‑flow thermostatic expansion valve for R134a refrigeran,Series TRAE 9 13 14 22 30 40 45 50MCt; it meters liquid refrigerant into evaporators, stabilises superheat under fluctuating load/pressure, prevents flood‑back and evaporator starvation in commercial cooling & heat‑pump systems.

Product Information

Product Features

• Balanced‑port construction maintains stable superheat across wide variations of condensing pressure and evaporator load
• Bi‑directional flow capability, suitable for heat‑pump reversible cycle operation
• External superheat adjustment for on‑site system tuning
• External equalizer connection to compensate evaporator pressure drop
• Stainless‑steel power element for corrosion resistance and extended service life
• Field‑replaceable power assembly and cage for service without full valve replacement
• Solid copper ODF braze‑in connections
• Large‑diaphragm design improves control sensitivity under partial‑load conditions
• Integrated permanent inlet strainer to protect internal valve components

Specific Application Scenarios

1. Commercial chiller OEMs & service technicians: Install or service large‑capacity water chillers using R134a; need stable flow control under variable building cooling loads.
2. Heat‑pump system contractors: Maintain reversible heating‑cooling heat‑pump units requiring bi‑flow expansion valve performance.
3. Medium‑temperature commercial refrigeration specialists: Retrofit or build walk‑in coolers and large refrigerated display systems running R134a under fluctuating ambient temperatures.
4. Industrial HVAC‑R maintenance teams: Replace failing conventional expansion valves on systems suffering super‑heat drift, flood‑back or starvation under high‑head‑pressure operating conditions.
