Abstract
A service connection valve that is configured for use on air conditioning and refrigeration units. The valve includes a pin guide that is separate from the poppet assembly and installed in the valve body prior to installation of the poppet assembly. In addition, the pin guide can be disposed in a large diameter flow passageway of the valve body. Further, the poppet assembly includes a seal that expands in diameter upon installing the poppet assembly into the valve body. The service connection valve provides high flow rates during charging and evacuation operations.
