　　The prime function of a rotary valve is to regulate the flow from one chamber to another while maintaining a good airlock condition. The product is mainly in dry powder or granular form.

　　In the dust filtration field good airlocks are essential on cyclone and bag filter applications in order that the manufacturer's quoted high dust collection efficiencies can be maintained. Airlocks are also important in the pneumatic conveying industry, where product is regulated into a high pressure conveying line while minimising air leakage.

　　旋转阀在许多散料输送和进料应用中至关重要，并发挥着多种功能。

　　当产品在系统或容器的不同部分之间移动时，无论是重力输送、真空输送还是用于过滤的压力输送，保持对过程的控制至关重要，而旋转阀门可以：

　　蕞小化压力或气流损失

　　提供计量和音量控制

　　调节进料速率

　　充当火焰或爆炸屏障

　　旋转阀可以提高生产效率、减少浪费，并保护产品免受通常可能存在的恶劣加工条件的影响。

　　滑杆式清洗型旋转阀：

　　Clean out of place configuration

　　Smooth product contact surfaces in food grade material

　　Rotor pockets scalloped and polished to Ra=0.8 μm (150 grit)

　　Shock resistant

　　The product contact surfaces of the valve are manufactured in 316 Stainless Steel and polished to a 150 grit finish, ensuring that there are no lodgement points allowing the product to flow smoothly. Furthermore, the valve is equipped with a slide rail mechanism allowing for the quick and easy removal of the rotor from the valve body. This addition substantially reduces the amount of downtime and the number of man hours required for the cleaning and maintenance of the rotor and valve internals.

　　Blowthrough / Blowing Seals

　　Blowthrough/blowing seals meet the specific needs of the pneumatic conveying industry, a natural extension to the Rotary Airlock; both products are used to regulate the flow of dry powder, dust or granular product, while maintaining an airlock.

　　The blowthrough/blowing seal has distinct advantages for the specialist as it introduces high pressure conveying air through the valve body and rotor pocket ensuring – HIGH EFFICIENCY THROUGHPUT WITH LOW EFFECTIVE PRESSURE DROP.

　　This is achieved by the fact that more blades are in contact for longer periods with the valve body resulting in less air leakage – and by blowing through the rotor each rotor pocket is efficiently emptied.

　　The Rotolok range of seals is robustly constructed with an emphasis on close tolerances and minimal eccentricities, making the unit suitable for the majority of pneumatic conveying applications.

　　防卡偏置式旋转阀：

　　Offset Airlock Valve

　　The prime function of a Rotary Valve is to regulate the flow of dust, powder and granular products from one chamber to another whilst maintaining a good airlock.

　　The granule type of product, especially if it is a plastic type, polythene or nylon etc., does not shear easily and consequently, without considerable care the standard drop-through type of valve leads to valve seizure and also considerable shock loadings.

　　To minimize these problems the Offset Rotary Valve ensures lower pocket fillage as its design means that the rotor is still being filled in the upward cycle with the pellets falling away at the shear point. Similarly, the pelican beak distributes the product across the full width of the rotor.

　　Bodies

　　Cast Iron, Stainless Steel or Aluminium precision bored.

　　End Covers

　　Cast Iron, Stainless Steel or Aluminium spigot located inbody for concentricity.
