Overview
The Sporlan OVE-10-GA is a Type O thermostatic expansion valve engineered for R-22 refrigeration and air conditioning systems. This 10-ton capacity valve delivers precise refrigerant metering through balanced port design, which maintains consistent valve operation regardless of downstream pressure fluctuations. The OVE-10-GA suits both commercial cooling and medium-temperature refrigeration applications requiring reliable, adjustable superheat control.
Key Features
- Balanced Port Construction: Pin and port alignment prevents pressure drop from affecting valve response, ensuring stable operation across varying load conditions.
- External Equalization: Allows accurate valve control in applications with significant evaporator pressure drop.
- Replaceable Thermostatic Element: Field-serviceable power element reduces downtime during maintenance cycles.
- Built-in Strainer: 12-mesh permanent inlet strainer protects the valve from debris and extends component life.
- Adjustable Superheat: Externally adjustable setting provides fine-tuning for specific system conditions.
- Synthetic Seating Surface: Tight shut-off during system off periods prevents refrigerant migration and oil logging.

Typical Applications
The OVE-10-GA is widely deployed in:
- Commercial air conditioning systems (rooftop units, split systems)
- Medium-capacity reach-in coolers and display cases
- Small to mid-range industrial refrigeration equipment
- Retrofits and field replacements in existing R-22 installations
- Systems requiring external equalization due to evaporator design
Compatibility & Replacements
Compatible With
- R-22 refrigerant systems rated 450 psi design working pressure or higher
- Systems with external equalization requirements
- ODF solder connection piping (1/4″ SAE or equivalent)
- Commercial air conditioning and refrigeration controllers
- Evaporators sized for 10-ton nominal capacity
Replaces / Drop-In Replacement For
The OVE-10-GA is a direct replacement for other Sporlan Type O balanced-port 10-ton valves with matching connection sizes and R-22 refrigerant specification. Always verify model number, refrigerant type, and connection sizes before ordering. Verify compatibility with your system integrator before ordering to ensure proper tonnage and charge type match.
Works With
- ODF solder connections (1/4″ SAE port, 5/8″ and 7/8″ ODF inlets/outlets)
- Capillary tube remote bulb sensing (5-foot standard)
- R-22 refrigerant systems only (not suitable for R-134a, R-410A, or R-404A)
- Commercial HVAC-R service and maintenance workflows
