Product Description

Parallel Guide Emergency Pressure Relief Valve

In addition to the normal vent capacity requirement by the PV valve / Flame Arrester. All large above ground storage tanks needs emergency Pressure relief caused due to fire in adjoining area. These relief requirements are recommended to be considered by making provision of Emergency Pressure Relief Valve as per API 2000 standard.

When fire occurs near the storage tank which is having flammable liquid the heat is transmitted through the tank walls causing to vaporize more quickly this condition create a relatively high pressure within the tanks vapor space in the absence of required emergency relief a blast could occur.

Function and Description :-

The PRECON Model No: PFCI/EPRV/2051 valve is a pressure relief valve for applications in which a high flow capacity is required. It is primarily used as an emergency pressure relief valve on silos, Process vessels and equipment, storage tanks etc, it offers reliable protection against excessive overpressure and prevents excessive product loss at pressures close to the set pressure. This emergency vent valves are weight loaded, Spring loaded, Hinged type etc, which provides tight seal under normal conditions and open only when the set pressure is attained and release the excessive volume of vapour generated by above condition.

Features & Benefits :-

  • Emergency Pressure relief valves provide high flow capacity.
  • Wide range of pressure settings to provide maximum tank protection while ensuring minimum gas loss.
  • Designed and manufactured to API 2000 / ISO 28300.
  • Seat leakage requirements of API 2000/ ISO 28300.
  • Low leakage rate.
  • Economic savings due to reduced product loss.
  • Alternative connection types available on request.
  • Valve sizing service assists optimum valve performance / cost specification.
  • Product Features
  • Designed and tested according to API2000.
  • Sizes available from 6”NB to 30” NB.
  • Vented to atmosphere.
  • Modular construction.
  • The inlet flanges are in accordance with ASME B16.5 150LB RF. Others on request
  • PTFE/FEP diaphragms effectively prevent the seat and pallet from sticking.
