The Model PV400 (top mount) Vacuum Relief Valve is an advanced design for vent from atmosphere applications. Utilizing the latest technologies, this relief valve provides protection against vacuum over pressure, prevents evaporative loss of product and helps contain odorous and potentially hazardous vapors.

Features

· Dual guide system provides for smoother valve stroke, less flutter and valve wear.

· Exceeds the most stringent standards for allowable leakage (far less than API2000 standard) and provides excellent set point accuracy (+/-3%)

· 10% overpressure to full lift.

· In-situ replacement for valve pallet and seat assembly

· Available in ANSI, DIN and HG/T20592~20635-2009 flanges
