一、进口卫生级无滞留球阀概述

进口卫生级无滞留球阀（美国威盾VTON），Sanitary without retention ball valve，也叫卫生级卡箍无滞留球阀，卫生级快装无滞留球阀，是指球与密封环之间的构造是完全包容的，所以根本没有残液滞留，也就不用担心出腐变的滞留液与新液相混的现象，消除了以往球型阀在与阀体间的死角的球阀。

Sanitary without retention ball valve (VTON, USA), also known as sanitary clamp without retention ball valve, refers to the structure between the ball and the sealing ring that is completely enclosed, so there is no residual liquid retention at all, so there is no need to worry about the phenomenon of stagnant liquid mixed with new liquid, eliminating the blind angle between the ball valve and the valve body in the past.

二、进口卫生级无滞留球阀产品特点

1、一只带有贯通腔的精确制造的球体被放置在阀门体内的两块法兰和两片PTFE阀门座之间。一个阀门轴芯经90°旋转可作用于该球体，因而能够开启或关闭阀门。

2、同时可增加阀座清洗接头,对球阀阀腔进行清洗,由排泄孔排出。

3、卫生级无滞留球阀简单的设计、使分解及再组装时不需任何工具、使用方便、便于清洗。材质有SUS304或SUS316L。

4、卫生级无滞留球阀密封性能好，绝大多数球阀阀座都采用聚四氟乙烯等弹性材料制造，一般这种软密封的密封性容易保证，所有广泛使用。
5、寿命长，由于聚四氟乙烯有良好的自润滑性，与阀体球体阀杆的摩擦磨损小，所有大大提高了球阀的使用寿命。
6、卫生级无滞留球阀可靠性高，球体与阀座不会擦伤，急剧磨损阀杆不会飞出，有防火、防静电功能。

1. A precisely manufactured sphere with a through cavity is placed between two flanges and two PTFE valve seats inside the valve body. A valve shaft core can act on the sphere through 90 ° rotation, thus enabling the valve to be opened or closed.

2. At the same time, a valve seat cleaning joint can be added to clean the ball valve chamber and discharge it through the discharge hole.

3. The sanitary grade non retention ball valve has a simple design, which eliminates the need for any tools during disassembly and reassembly, is easy to use, and is easy to clean. The materials are SUS304 or SUS316L.

4. The sanitary grade non retention ball valve has good sealing performance, and the vast majority of ball valve seats are made of elastic materials such as polytetrafluoroethylene. Generally, the sealing performance of this soft seal is easy to ensure, and it is widely used.

5. Long service life, due to the good self-lubricating property of polytetrafluoroethylene, the friction and wear with the valve body and valve stem are small, greatly improving the service life of the ball valve.

6. The sanitary grade non retention ball valve has high reliability, and the ball and valve seat will not be scratched. The valve stem will not fly out due to sharp wear, and it has fire and anti-static functions.

三、进口卫生级无滞留球阀产品参数

规格：1"-2"
材质：SUS304，SUS316
连接形式：插销，焊接，螺纹，卡箍
应用范围：乳制品、啤酒、食品、饮料、制药等工业领域的储罐和容器的清洗

CFQF型球阀是一款卫生型球阀，用于物料输送。这种阀门的应用范围包括食品，饮料加工，以及制药和化学工业等领域。

完全贯通的阀门腔设计不会产生任何流体阻力。因此使得QF5型阀门成为用来处理黏性或含有颗粒物的流体的最佳选择。
