Spirax-Sarco 54663 R410A 46-Ton Externally Equalized TXV, Type TGEL 40

Description

Spirax-Sarco Type TGEL 40 Thermal Expansion Valve — SKU 54663

The Spirax-Sarco 54663 is a heavy-duty, externally equalized thermal expansion valve (TXV) engineered for large commercial and industrial refrigeration and air conditioning systems operating on R410A refrigerant. Designed under the proven Type TGEL series, this valve delivers precise superheat control and reliable capacity regulation in demanding high-pressure applications.

Key Features

• Straight body configuration for streamlined inline installation
• 1-1/8″ ODF inlet x 1-3/8″ ODF outlet connections
• Rated capacity of 46 tons on R410A refrigerant
• Maximum Operating Pressure (MOP): 667 PSI — suited for high-pressure R410A systems
• Externally equalized design for accurate superheat control across long evaporator circuits
• 60″ capillary tube for flexible remote bulb placement
• Number 40 orifice for precise refrigerant metering at rated capacity
• Includes bulb strap for secure remote sensing bulb mounting
• Type TGEL 40 classification

Application

This valve is ideal for large-tonnage commercial HVAC and refrigeration systems where R410A is the system refrigerant. The externally equalized port compensates for pressure drop across the evaporator, ensuring consistent superheat control regardless of evaporator load variations. The 60″ capillary tube provides installation flexibility when the sensing bulb must be located away from the valve body.
