Frontseating Valves
Parker’s Frontseating Valves are used as service valves
in split air-conditioning and heat-pump systems. The
valves isolate sections of a system for servicing and
provide a means for charging refrigerant into a unit.
Application
• Residential split-system air conditioners and heat
pumps
Agency Approvals
U.L. recognized; File No: SA5188
CSA approval; File No. LR86182-2
Technical Information
Specifications
* Brass Bar per ASTM-B16, Alloy C36000.
** Due to the numerous manufacturers of refrigerant oils and
continuous changes of additives, compatibility can not be
guaranteed. Please contact Parker for compatibility of
refrigerants and refrigerant oils not listed.
Features and Benefits
• The simplest of service valves providing basic
shut-off, charging, and evacuating capabilities.
• Captivated stem-design eliminates the traditional
retaining ring, reducing the potential for injury.
• Multiple end-configurations are available, along
with assemblies, to meet the unique needs and
flow patterns of a unit.
• Use of a standard Allen wrench provides
actuation of the valve.
• Brass body and copper-connection tubes virtually
eliminate corrosion-related problems.
• Copper-sweat connections provide basic ends
for brazing and eliminate the need for flux,
simplifying the installation process.
• Flare connections also available as an alternative
to sweat connections.
