Liquefied petroleum gas is the most popular aerosol propellant c.84% of global mkt, howeverit is unsustainable as it extracted from depleting, non-renewable resources (natural gas & oil);contributes substantially to VOC emissions; & it is highly explosive & flammable & thussurrounded by H&S regulations which drive up the cost of all associated activities.Compressed inert gas (air or nitrogen) is an alternative aerosol propellant offering majoradvantages over LPGs: renewable resource,non-explosive/flammable, H&S regulations nolonger apply therefore lower life cycle cost. However, its use is limited when used inconjunction with a standard aerosol valve: the pressure in the can drops as product is used &thus spray characteristics deteriorate (unacceptable variations in particle size & dischargeflow rates). To address this issue, The Salford Valve Company has developed & patented, atlab scale, a unique suite of aerosol valves ‘Eco-valve’, which enable a standard aerosol tofunction effectively using a compressed gas propellant without the need for specialisttechnology. Advantages include: excellent spray characteristics over lifecycle of the can; stepchange in performance compared to current technology; standard filling technique&components & can be fitted to a standard can; suitable for all applications & industry sectorsincl. metered & continuous flow.The company now seek to advance 3 Eco-valve types from bench top to pre-productionprototype (applicable to c.90% of aerosol applications): Super Single Gasket, Metered & LowLoss. Scale up will involve further design & development of the valves & pre-productionmoulds to ensure the valves can be mass produced at levels demanded by the global mkt.With the global aerosol valve mkt already a $617M industry & with significant policy driversfor environmentally friendly & safe consumer products, the development of the Eco-valverepresents a major business opportunity, with mkt entry expected in Q4 2015

液化石油气是最受欢迎的气溶胶推进剂，占全球市场的84%，但它是不可持续的，因为它是从枯竭的不可再生资源中提取的（天然气和石油）;对挥发性有机化合物排放贡献很大;它具有高度爆炸性和易燃性，因此受到H&S法规的限制，这会增加所有相关活动的成本。压缩惰性气体（空气或氮气）是一种替代气溶胶推进剂，与LPG相比具有以下主要优势：可再生资源、非爆炸性/易燃性、不再适用H&S法规，因此寿命周期成本较低。然而，当与标准气雾剂阀结合使用时，其使用受到限制：罐中的压力随着产品的使用而下降，因此喷雾特性变差（颗粒尺寸和排放流量的不可接受的变化）。为了解决这个问题，索尔福德阀门公司已经开发和专利，在实验室规模，一套独特的气雾剂阀“生态阀”，使标准气雾剂有效地使用压缩气体推进剂，而不需要专门的技术。优点包括：在罐的整个生命周期内具有出色的喷雾特性;与当前技术相比，性能有阶跃变化;标准灌装技术和组件，可安装到标准罐上;适用于所有应用和工业部门。该公司目前正在寻求将3种生态阀类型从实验室顶部推进到预生产原型（适用于约90%的气雾剂应用）：超级单垫圈，计量和低损耗。扩大规模将涉及阀门和预生产模具的进一步设计和开发，以确保阀门可以按照全球市场的要求进行大规模生产。全球气雾剂阀门市场已经是一个价值6.17亿美元的行业，并有重要的政策驱动力，环保和安全的消费品，生态阀的开发代表了一个重大的商业机会，预计将于2015年第四季度进入市场
