API 607 FIRE SAFE BALL VALVES

Standards confirm to API 607 4th/5th/6th, ISO 10497-5, BS 6755 Part II
During fire hazard, overheated pipeline or similar situation, the valve should be closed to prevent or hinder the flammable fluid (liquid, gas or gases formed from liquid phase) from passing for a given period of time. Where any leakage occurs, the leakage rate should be controlled at an allowable quantity.

Where any leakage occurs, the leakage rate should be controlled at an allowable quantity.

The purpose

During fire hazard, overheated pipeline or similar situation, the valve should be closed to prevent or hinder the flammable fluid (liquid, gas or gases formed from liquid phase) from passing for a given period of time. Where any leakage occurs, the leakage rate should be controlled at an allowable quantity.

Design

Seats/Ball interface the seat is designed with a lip which secures the metal to metal seating once the soft seal insert is melting down. Valves become trunnion mounted and as such at low pressure, the contact seat/ball is helped by springs. When working at high pressure, the pressure keeps the upstream seat in contact with the ball. To avoid external leakage, all sealing areas (body seal, stem packing) or a secondary sealing system, mostly graphite must be provided for this purpose.

Industry Applied

Chemical, Petrochemical, Oil & Gas, paraffin/ Kerosene, Emergency cut-off valves


Medium / fluid
