- Capacity: 3 Ton
- Inlet connection: 3/8″ ODF (sweat)
- Outlet connection: 1/2″ ODF (sweat)
- Capillary tube length: 5 feet for flexible bulb placement
- External equalizer: 1/4″ ODF connection for accurate superheat sensing in systems with significant pressure drop
- Body style: Straight-through for simplified installation and minimal pressure drop
- Superheat: Adjustable for field-tuned system optimization
- Integrated check valve: Enables bi-directional flow for heat pump applications
- Series: NXT — Copeland’s next-generation TXV platform
Product Details
The straight-through body design minimizes internal pressure drop and simplifies line routing during installation. The 5-foot capillary tube provides ample reach to position the sensing bulb at the optimal location on the suction line. The 1/4″ ODF external equalizer port ensures accurate superheat measurement downstream of the distributor or evaporator, making this valve well-suited for multi-circuit evaporator coils.
The built-in check valve allows refrigerant flow in both directions, making the Copeland 091018 an ideal choice for heat pump systems where the refrigerant circuit reverses between heating and cooling modes. Adjustable superheat allows technicians to fine-tune performance to match specific system requirements and operating conditions.
Applications
- R410A split-system air conditioners
- R410A heat pump systems (heating and cooling modes)
- 3-ton residential and light-commercial evaporator coils
- Multi-circuit evaporator coils requiring external equalization
