Danfoss 148B3746 SNV-ST needle valve (1/4 in) 148B4180

Product Description

The Danfoss 148B3746 is an SNV-ST stop needle (gauge) valve configured as a 1/4 in service/gauge valve for refrigeration and industrial instrumentation. It features a steel low-temperature body, 1/4 in NPT inlet and outlet connections (bottom 1/4 in MPT x side 1/4 in FPT), bi-flow angleway orientation, and metal-to-metal backseating that permits spindle seal replacement while the valve remains pressurized. The valve is rated to 52 bar (754 psig) and -60 to 150 C.

• SNV-ST stop needle/gauge valve, 1/4 in NPT connections (bottom 1/4 in MPT x side 1/4 in FPT)
• Steel low-temperature body with Cr3/TLP coating, bi-flow angleway orientation, metal-to-metal backseating
• Maximum working pressure 52 bar (754 psig); temperature range -60 to 150 C (-76 to 302 F); compatible with common refrigerants including R717 and R744
