Sporlan 130594 SVE-4-C Expansion Valve

The Sporlan 130594 is a professional-grade SVE-4-C thermostatic expansion valve engineered for precision refrigerant metering in R22 commercial refrigeration and air conditioning systems. This high-capacity 4-ton valve features a 1/2" ODF inlet and 7/8" ODF outlet, utilizing ODF solder connections to ensure a leak-proof, high-strength bond within the liquid line. Designed with an externally equalized port, the Sporlan SVE series maintains optimal superheat control even in systems with significant evaporator pressure drops, preventing liquid floodback and protecting the compressor from damage.

Built with a durable brass body and a 5-foot capillary tube, this TXV for R22 includes a "C" thermostatic charge, specifically calibrated for standard refrigeration temperatures. The externally adjustable superheat allows technicians to fine-tune system performance post-installation for maximum efficiency. Its large flat stainless steel diaphragm and field-replaceable thermostatic element ensure responsive control and longevity under demanding commercial cycles. When retrofitting or repairing older R22 equipment, this valve provides the exact flow characteristics required to maintain design evaporator temperatures and capacity.

• Precise Refrigerant Control: The Sporlan 130594 regulates flow with a 4-ton capacity to maintain stable superheat across varying load conditions.
• Enhanced System Reliability: Features an externally equalized design to compensate for pressure drops, preventing premature compressor wear.
• Robust Construction: Forged brass body and silver-soldered joints provide maximum resistance to corrosion and high-pressure leaks.
• Field Serviceable: The SVE-4-C is designed with accessible internal parts and replaceable elements for straightforward maintenance.
• OEM Compatibility: Serves as a direct high-performance replacement for 4-ton R22 expansion valves in commercial AC and refrigeration racks.

Is the Sporlan SVE-4-C compatible with refrigerants other than R22?
This specific model is calibrated with a "C" charge intended for R22. Using it with incompatible refrigerants may lead to incorrect superheat and poor system performance.

When should I choose an externally equalized valve over an internal one?
If your evaporator uses a refrigerant distributor or has a pressure drop exceeding 2 psi, an externally equalized valve like the 130594 is required to maintain accurate superheat sensing.

Can the superheat setting be adjusted manually?
Yes, the Sporlan 130594 features an externally adjustable superheat stem, allowing you to increase or decrease flow to match the specific needs of the evaporator coil.
