Sporlan Controls 108693 Thermostatic Expansion Valve Overview
The Sporlan Controls 108693 is a thermostatic expansion valve (TXV) engineered for reliable refrigerant metering in R-500 refrigeration and air conditioning systems. Designed and manufactured by Sporlan — a trusted name in refrigeration controls — this valve delivers precise superheat regulation to protect the compressor and maximize system efficiency.
Key Features
- Designed for use with R-500 refrigerant systems
- 3/8″ inlet (liquid line) x 1/2″ ODF outlet (evaporator) connections for straightforward installation
- 30″ external equalizer capillary line for accurate downstream pressure sensing, ideal for evaporators with significant pressure drop
- External equalizer design ensures stable superheat control across varying load conditions
- Sporlan’s proven valve construction for long service life and consistent performance
- Suitable for commercial refrigeration and HVAC applications using R-500 refrigerant
Why Choose an External Equalizer TXV?
An externally equalized TXV senses evaporator outlet pressure directly at the suction line, rather than at the valve outlet. This is essential when evaporator pressure drop is significant — it prevents hunting, ensures stable superheat, and protects the compressor from liquid slugging. The 30″ external equalizer line on the Sporlan 108693 provides the flexibility needed for a clean, accurate installation.
