Totaline Refrigerant Charging Pin NRV Valve (Pack of 10) – Product Description
The Totaline Refrigerant Charging Pin NRV Valve (Pack of 10) is a premium-quality replacement Schrader valve core (Non-Return Valve) designed for use in air conditioning and refrigeration systems. It is an essential HVAC service component that controls refrigerant flow through the service port while automatically preventing backflow and refrigerant leakage. This valve core ensures safe, efficient, and reliable refrigerant charging, recovery, vacuuming, and pressure testing, making it an indispensable spare part for HVAC technicians and refrigeration professionals.
Manufactured from high-grade brass with a precision-engineered stainless steel spring and high-quality sealing gasket, the Totaline NRV valve is built to withstand high operating pressures and repeated service cycles. Its precision-machined construction provides a secure, leak-proof seal that prevents refrigerant loss and helps maintain the correct system pressure. The automatic spring-loaded mechanism opens only when connected to charging equipment and immediately seals when disconnected, protecting the refrigeration system from refrigerant leakage and contamination.
Compatible with most standard HVAC service ports, this charging pin NRV valve is suitable for refrigerants including R22, R32, R134a, R404A, R407C, R410A, R507, and other compatible refrigerants, depending on the service valve specifications. It can be used in split air conditioners, window ACs, refrigerators, freezers, cold storage units, water chillers, heat pumps, and commercial refrigeration equipment.
The valve core is easy to install and replace using a standard valve core removal tool, reducing service time and improving maintenance efficiency. Supplied as a pack of 10, it is an economical choice for HVAC workshops, refrigeration service centers, and professional technicians who frequently perform AC servicing and repairs.
