    • A dispensing valve has a pressure balancing structure ucture for enabling easy opening of the valve and an improved drive mechanism (20) providing a relatively higher force for opening the valve; the balancing structure has a balance piston (54) on a nose of a normally closed poppet valve (14), the piston is on a floppy mount and is sealed to a balance cylinder in the pressurized beverage line forming a balance chamber upstream of the piston, the chamber is vented to atmosphere to relieve beverage pressure on most of the area of the poppet valve to reduce the opening force required; the drive mechanism includes an electric solenoid (16) having an elastic tension spring in the solenoid plunger, the spring elastically connects the plunger to the poppet valve to generate an improved and greater force. A dispensing system has several of these valves with a single low power transformer for all the valves. A method of dispensing pre-mix carbonated beverage has the new steps of balancing the beverage pressure upon the upstream side of a poppet valve so that it is relatively easy to open the valve, and elastically applying an opening force upon the poppet valve to pop it open when the elastic force exceeds the required opening force.
    • 分配阀具有用于使阀易于打开的压力平衡结构结构和提供用于打开阀的相对较高的力的改进的驱动机构(20); 所述平衡结构在常闭提升阀(14)的鼻部上具有平衡活塞(54),所述活塞位于软盘安装件上并且被密封到所述加压饮料管线中的平衡缸,从而在所述活塞的上游形成平衡室 ,该室被排放到大气中以减轻提升阀的大部分区域上的饮料压力,以减小所需的打开力; 驱动机构包括在螺线管柱塞中具有弹性拉伸弹簧的电磁螺线管(16),弹簧将柱塞弹性地连接到提升阀以产生改进的和更大的力。 分配系统具有几个具有用于所有阀的单个低功率变压器的阀。 分配预混碳酸饮料的方法具有平衡在提升阀上游侧的饮料压力的新步骤,使得它相对容易打开阀门,并且在提升阀上弹性地施加打开力以将其推出 当弹力超过所需打开力时打开。
