Allstyle AS-RP31117 Bi-flow Txv with Check Valve 1.5-2 Ton

Product Description

The ALLSTYLE AS-RP31117 is a bi-flow thermostatic expansion valve (TXV) with an integrated check valve, designed for use in residential split-system heat pump applications. Operating on R-410A refrigerant, it meters refrigerant flow in both directions, eliminating the need for a separate check valve in the liquid line. Nominal capacity is rated at 1.5 to 2 tons. Licensed HVAC technicians install this component as part of a heat pump refrigerant circuit, where precise metering in both heating and cooling modes is required for proper system efficiency and reliability.

This valve is suited for residential heat pump systems running R-410A refrigerant in the 1.5 to 2 ton range. Its bi-flow design allows refrigerant to flow in both the cooling and heating directions through a single valve, simplifying installation and reducing the number of components in the refrigerant circuit. It is typically installed in the liquid line between the indoor coil and the outdoor unit on heat pump systems where reversible refrigerant flow is required.

Key Features

• Bi-flow design meters refrigerant in both directions for heat pump operation
• Integrated check valve eliminates the need for a separate check valve in the liquid line
• Rated for R-410A refrigerant systems
• 1.5 to 2 ton nominal capacity suits residential heat pump applications
• Replaces or matches the AS4VPT2 model specification

Compatibility

Designed as an OEM-style replacement TXV for residential R-410A heat pump systems in the 1.5 to 2 ton nominal capacity range.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 refrigerant handling certification. Recover all system refrigerant before removing the existing valve, and ensure the system is fully depressurized before disconnecting any refrigerant lines. Follow the equipment manufacturer's guidelines and applicable mechanical codes when brazing or connecting the valve in the liquid line. After installation, leak-test all connections before recharging the system with R-410A.
