Raypak H000173 TX Valve Is An OEM 8-Ton Thermostatic Expansion Valve For P5350 Systems, Ensuring Precise Refrigerant Flow And Reliable Heater Performance
The Raypak H000173 TX Valve is a genuine OEM 8-ton thermostatic expansion valve designed for Raypak pool and spa heating systems using the P5350 refrigeration platform. This component precisely regulates refrigerant flow into the evaporator, ensuring correct superheat, efficient heat transfer, and stable system operation under varying load and temperature conditions.
The TX valve plays a critical role in overall heater performance. By accurately metering refrigerant, it protects the compressor from liquid floodback while maximizing heating efficiency and system longevity. A failing or restricted expansion valve can lead to poor heating output, fluctuating water temperatures, excessive compressor cycling, icing conditions, or complete system shutdown.
Common failure symptoms include reduced heating capacity, inconsistent temperature control, abnormal system pressures, frost buildup, or compressor strain. Replacing a worn or malfunctioning valve with the OEM Raypak H000173 TX valve restores proper refrigerant control, improves energy efficiency, and helps prevent costly damage to other refrigeration components.
Manufactured to Raypak’s exact specifications, the H000173 TX valve ensures proper fit, reliable operation, and long-term durability in demanding pool and spa environments. OEM replacement is strongly recommended to maintain factory performance standards and system reliability.

Please be advised that certain manufacturers - including Pentair® (with their TradeGrade® products), Jandy®/Fluidra® (with their Trade Series Exclusive™ products), and Hayward® (with their Expert Line® products) - do not honor manufacturer warranties on specific product lines purchased online.
These policies are intentionally enforced by the manufacturers to prevent customers from purchasing the same products at lower prices online.
Warranty coverage for these products is generally only available when purchased in person from an authorized local dealer.
While we strive to take care of our customers by offering the lowest possible prices on brand new, genuine products, we do not provide warranty coverage ourselves, nor can we guarantee that the manufacturer will honor the warranty on products purchased from our online store.
It is the buyer’s responsibility to confirm warranty eligibility directly with the manufacturer before making a purchase.
If you are a local customer, you may be able to purchase these items in-store and obtain manufacturer warranty coverage. However, for many of our customers across the country, paying significantly more locally just to access a manufacturer warranty often doesn’t make financial sense, especially when some local suppliers charge considerably higher prices.
By completing your purchase, you acknowledge and agree that we are not responsible for warranty support or claims denied by the manufacturer due to their online sales restrictions.
