HONGSEN CVR Series Right-Angle Refrigeration Check Valves
Description
Product Overview
HONGSEN CVR Series check valves are right-angle, one-way valves designed for refrigeration and air-conditioning piping systems where a 90-degree flow path is required.
The valve allows refrigerant to flow in one specified direction while helping prevent reverse flow. Its right-angle body configuration can simplify piping layouts in installations where straight-line space is limited.
CVR models use ODF solder connections and are suitable for liquid, suction-gas and hot-gas piping in refrigeration, cold-storage and air-conditioning equipment.
Key Features
- Right-angle check-valve configuration
- Prevents reverse refrigerant flow
- ODF solder connections
- Suitable for liquid, suction-gas and hot-gas piping
- Low minimum opening-pressure differential
- Reliable valve-seat and sealing performance
- Suitable for applicable HCFC and HFC refrigerants
- Connection sizes from 7/8 to 1-3/8 inch
- Suitable for space-limited refrigeration piping layouts
