Ruud pd619090 Expansion Valve Kit Txv

Product Description

The RUUD pd619090 is a thermostatic expansion valve (TXV) kit designed to meter refrigerant flow into the evaporator coil of a split-system or packaged refrigeration unit. The TXV maintains proper superheat by regulating refrigerant flow in response to evaporator outlet temperature and pressure, protecting the compressor from liquid slugging and optimizing system efficiency. This kit is installed by licensed HVAC-R technicians during new system commissioning or as a field replacement when the original valve fails or is mismatched to current system conditions.

The pd619090 expansion valve kit is suited for residential and light commercial HVAC applications where a factory-matched or OEM-equivalent TXV is required. Installation as a kit typically includes the valve body and any associated fittings or hardware needed to complete the replacement. Consult the system service manual to confirm valve sizing and refrigerant compatibility before installation.

Key Features

• OEM-style TXV kit for accurate refrigerant metering and superheat control
• Packaged as a complete kit with associated installation components
• Designed for field replacement or new installation in split and packaged systems
• Helps protect compressor from liquid refrigerant slugging
• Supports proper system efficiency and evaporator performance

Compatibility

Designed as an OEM-style replacement expansion valve kit for RUUD refrigeration and air conditioning systems. Verify system refrigerant type and valve sizing requirements against the equipment service manual prior to installation.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC-R technician. Recover all system refrigerant and relieve system pressure before removing the existing valve. Braze or connect fittings per the system service manual and applicable mechanical codes, then leak-check all joints before recharging. Recheck system superheat and subcooling after recharge to confirm correct valve operation.
