Tankflo, Girard Equipment USA’s newest bottom outlet valve for ISO tank containers, has received recognition and approval under the European directive EN 14433:2006 for Tank Equipment for the Transport of Liquid Chemicals-Foot Valves. The analysis was conducted by Bureau Veritas UK Ltd at one of Girard’s service facilities in Linden NJ. The test consists of a rigorous performance review after the valve was subject to extreme pressures and mechanical stress procedures designed to replicate the sometimes intense environment of tank containers. “Criteria like EN 14433:2006 demonstrate the tank container industry’s determination to produce the safest and most dependable packaging equipment available for transporting hazardous commodities safely and efficiently” said a company spokesperson. The Tankflo bottom outlet valve has been in field trial service since 2008 with several operators in the United States and Europe with no reported service issues. The Tankflo valve employs an integrally joined butterfly valve to a bottom outlet valve equipped with a poppet that lifts away from the valve’s internal flow paths. This creates a full, unobstructed flow path that will allow for fast unloading rates and help promote a superior ability to be adequately cleaned due to the limitation in liquid contact surfaces. The foot valve uses a spring-cam mechanism with a limited number of moving parts. This spring-cam mechanism has also been tested to be actuated 10,000 times without any degradation to its performance. The device is virtually indestructible—so much so that the company has offered the valve with a “guaranteed for life” policy. If the spring cam ever needs replacement, Girard will provide a new device free of charge.

Tankflo，吉拉德设备美国{zx1}的底部为ISO罐式集装箱的排气阀，已得到了承认，并根据欧洲指令批准EN为了罐式储运设备14433:2006的液体化工品运输，脚踏阀。 这项分析是由法国国际检验局在英国公司在新泽西州林登吉拉德的服务设施之一。该项测试分为瓣膜后，受到极大的压力和机械应力，旨在复制有时罐式集装箱激烈的环境程序，严格的业绩审查。 如en 14433:2006“展示了坦克的标准货柜业的决心，生产xxx和最可靠的包装设备，运输危险商品的安全，高效”现有公司发言人说。 在Tankflo底孔阀已在现场试验服务，在美国和欧洲的几家运营商没有报告自2008年服务问题。 在Tankflo阀采用一个完整地加入了蝶阀的底孔阀的小鬼的升降机远离阀内部流道设备。这将创建一个完整，通畅的流通路径，使快速装卸率，有利于推动建立良好的能力得到充分的清洗，由于液体的表面接触的限制。 脚阀用弹簧的运动部件的数量有限的凸轮机构。今年春天，凸轮机构也已通过测试，无需任何驱动的性能下降10,000次。该设备实际上是坚不可摧的，以至于该公司已提供了保障“生命”的政策阀。如果春天都需要更换凸轮，吉拉德将提供一个新的设备是免费的。
