SINGLE-PART DIFFERENTIAL PRESSURE DEVICE ORIFICE PLATE DATA SHEET FVE An orifice plate of corner tap type is used for differential pressure outlet, and the orifice plate is unitized with the differential pressure outlet. It provides high reliability compared to an orifice plate with ring (Type FVA), it is of size 25A to 350A and is appropriate for medium and high pressure. SPECIFICATIONS Type: Corner taps Calculation standard: According to concentric edge JIS Z 8762-1995 [ ISO 5167-1:1991 ] Nominal pipe size: 25A to 350A These orifice plates with CARRIER RINGS can be supplied for nominal pipe sizes up to 1000A.
