• Pressure relief function (exceeding atmospheric pressure)
• Liquid overflow protection
• Release small air pocket from pipeline
• Increasing of pump efficiency
• Less system energy
• Maintenance free

Introduction

While the system is flowing and under pressure, air release valves continually and automatically exhaust the small quantities of air that would otherwise collect at system high points. This ensures the system will remain free of trapped air (and sewage gases) thereby increasing system efficiency and reducing pumping cost.

• Meet the latest international rule requirement of API 2000, EN 12874 and ISO 16852
• Protection against explosion and deflagration flame
• High flow capacity and minimum pressure loss
• Available bi-directional flow and flame passage
• Available vertical and horizontal installation
• Very easy maintenance for quick cleaning
• High performance chemical resistance material

 Introduction

The flame arrester is designed to prevent flame transmission when flammable gas/air- or vapor/air-mixtures are present. The model FA in-line flame arrester is designed, manufactured and tested according to API 2000, EN 12874 and ISO 16852. Body material of arrester is available for nodular cast iron, cast steel, stainless steel grade 304, 316, 316L and special alloy steel for chemical resistance. The material of element is available for stainless steel grade 316L or special alloy steel for chemical resistance. The flame element is constructed with crimped ribbon metal.

Description of Protective System:
The in-line, bi-directional, deflagration flame arresters types FA-02; FA-03; FA-04; FA-05; FA-06; FA-08; FA-10; FA-12 are to prevent a flame transmission in case of deflagration of flammable gas – and/or vapour/air mixtures of the explosion group llA, at a maximum operating pressure po which is defined below and at maximum operational temperature of the flame arrester To = +60°C. Flame arresters are consists of flame arrester element tight between two flanges.

Introduction

The model BV/BS pressure vacuum relief valves designed manufactured and tested according to the API 2000 standard. The model BV/BS pressure vacuum relief valves used to relieve excess pressure and vacuum that has developed in a tank. To avoid product loss, BV/BS pressure vacuum relief valves are recommended for use on atmospheric storage tank. The set pressure and relieving pressure shall be consistent with the requirements of the standard according to which the thank was designed and fabricated. The model BV/BS can be manufactured the range of pressure and vacuum setting form ±22 mm W.C to ±8000 mm W.C. The model BV type is weight-loaded type with minimum setting ±22 mm W.C and maximum setting ±700 mm W.C. The model BS type is spring-loaded type over weight loaded type

The materials for BV/BS shall be selected for the stored-product service temperatures and pressures. Also, the materials should be compatible with the product stored in the tank and with any products formed in the vicinity of the relief valve during filling and discharge. Usually the materials are available in Aluminum, Carbon Steel, Stainless Steel grade 304, 316 and 316L to suit individual requirements.
