HCV01

The HCV01 check valve is designed to fit between two ASME BPE compliant clamp fittings, sealing on the ID of the tube using FDA approved EPDM O-rings. The compact 316 stainless steel design is suitable for a wide range of duties in steam, liquid and gas service, including pressure relieving and anti-vacuum applications. Standard valves have metal-metal seating. A number of soft seal and spring options are also available.

Size Range 3/4″ – 4″ ASME BPE compliant clamp fittings
Material 316L stainless steel
Opening Pressure 8, 35, 100 & 240 mbar
Options Metal-metal and soft seat options
Various seal materials
