1 Scope
This document covers the vapour manifold vent valve used to provide controlled venting of the vapour manifold to atmosphere.
It specifies the performance requirements and the critical dimensions of the vapour manifold vent valve. It also specifies the tests necessary to verify compliance of the equipment with this document.The service equipment specified by this document is suitable for use with liquid petroleum products and other dangerous substances of Class 3 of ADR [1] which have a vapour pressure not exceeding 110 kPa at 50 °C and petrol, and which have no sub-classification as toxic or corrosive.

4 Functions
The vapour manifold vent valve
一shall provide controlled venting of the vapour manifold;
一shall be vapour tight when closed;
一may be provided with a flame arrester;
一may be self-operating;
一may be provided with an open/ closed indicator;
5 Design characteristics
5.1 General
The vapour manifold vent valve shall provide a controlled vapour path between the vapour manifold and atmosphere. The vapour manifold vent valve shall be closed during the process of vapour recovery, both loading and delivery. Self-operating valves shall not compromise the vapour recovery process. Such valves shall be of the resealing type, and shall be designed to prevent unauthorized adjustment of the self-operating mechanism. When not activated the valve shall return automatically to its passive state.
