INTRODUCTION
Pressure relief valves are used on liquid storage tanks and other process vessels or systems to prevent structural damage due to excess internal pressure. Storage tanks are pressurized when liquid is pumped in, compressing the existing vapor or when rising temperatures cause increased evaporation or expansion of existing vapor. To prevent tank damage, vapor must be allowed into or out of the tank at specified pressure condition. The volume rate of venting depends upon the tank size, volatility of the tank contents, the pumping rates and the temperature.

DESIGN AND FUNCTION
Tank protection equipment typically includes an operating valve which is designed to provide pressure relief under normal pump in thermal breathing conditions.

PRESSURE RELIEF
 As the pressure in the storage tank increases. When the set pressure is reached, the pressure pallet lifts and relieves to atmosphere (or to a header if it a pipe away valve).Model NK-BV10, NK-BV13 of quick-opening type is designed for emergency relief of pressure above capacity that supplied by a standard operating valve used on tanks, piping and low pressure vessels. It provides relief from excessive internal pressure that may cause tank damage. Model NK-BV10, NK-BV13 has self-draining housing body and drip rings to protect seating surfaces from condensation and freezing. Model NK-BV13 is for use where pressure relief is required and all relieving vapors must be piped away.
