KV球阀，配有一个孔球作为锁定装置。
球阀/蝶阀
GEA ball valves (KV) are designed for installation in industrial heating and refrigeration systems. The closing device is a bored through ball that opens and closes the pipe by horizontal rotation in relation to the flow direction. The 90° rotation is exerted via the shaft and is either by a hand-operated lever or by electric or pneumatic actuators. By default the bore size in the ball is smaller than the inside diameter of the pipe, versions with full clearance are also available upon request.
技术特征
- 采用钢或不锈钢
- 根据德国 DIN EN12284、AD2000 系列 W 选择阀体材料
- 工作介质：符合EN 378-1的乙二醇基冷盐水制冷剂，例如NH3、R22、R134a 以及与冷冻机油的混合物；中性、气体和液体介质；乙二醇基冷盐水
标准球阀的孔径较小。
球配有排气孔，仅在流动方向上紧闭。
