W9^TM Sampling Valve

The W9^TM is the standard Keofitt^® sampling valve, the valve others are measured to. Designed for sampling medium viscosity products, with particles up to 3 mm in diameter, if fitted with PTFE membrane and 2mm when fitted with silicone or EPDM membrane. The main product range W9^TM valves are used for products that have about 0-1,000cP in viscosity.

The W9^TM valve is used in a range of applications, such as breweries, dairies, pharmaceutical and biotechnological industries, with wide range of products such as:

• Unprocessed Milk / 未加工奶品
• Medical solutions / 藥品溶劑
• Filtered and unfiltered beer / 過濾及未過濾啤酒
• Perfume / 芳香劑
• Creams and lotions  / 乳液及化妝塗劑 

The W9^TM valves come with a variety of valve bodies and heads that fit most situation. The bodies come with welded or clamp connection, the heads come with diffrent operations and membranes.
