Tri-Clover®LKB蝶阀
Central States Industrial (CSI) offers the Tri-Clover® LKB butterfly valve from Alfa Laval. Either remotely controlled by an actuator or manually operated with a handle, the Tri-Clover LKB butterfly valve is designed to provide years of dependable service in sanitary stainless steel fluid handling systems.
The LKB valves are built for use in a wide range of applications and working pressures. LKB is FDA compliant and available with a variety of handle options.
Models
- LKB51手动阀门
- LKB53驱动阀
LKB is available in the following sizes: 1, 1.5, 2, 2.5, 3, 4, and 6 inch.
阿尔法拉瓦尔is a leading global supplier of products and solutions within the key technology areas of heat transfer, separation, and fluid handling.
应用程序
Alfa Laval的Tri-Clover LKB蝶阀专为广泛的应用和工作压力而设计。这些符合FDA标准的阀门提供可靠的性能和平滑操作。阀杆直径提供特别低的流动阻力，确保低粘度和中粘度产品的温和产品处理。
WORKING PRINCIPLE
通过致动器远程控制LKB或通过手柄手动操作。执行器由三种标准版本，常闭（NC），常开（NO）和空气/空气激活（A / A）进行。致动器设计成使得活塞的轴向运动被变换成轴的90°旋转。当阀盘接触蝶阀的密封环时，致动器的扭矩增加。用于手动操作的各种手柄选项机械地将阀门固定在其开放，关闭或中间位置。
标准设计
The valve consists of two valve body halves, a valve disc, bushings for the disc stem, and a seal ring. The valve is assembled by means of screws and nuts. Two actuator sizes, ø 85 mm (3.35 inch) and ø 133 mm (5.24 inch), cover all valve sizes. The actuator is fitted onto the valve by means of a bracket and screws. The handle for manual operation is fitted onto the valve by means of a cap/block system and a screw. The LKB is available with either welded ends or Tri-Clamp® sanitary connections.
CONTROL EQUIPMENT
控制和指示可以配置有气动致动阀。选项包括Tri-Clover绿色顶部,Alfa LavalThinktop®., and横向安装的指示单元.

LKB Ultrapure.
The LKB butterfly valve is also available in the UltraPure execution, which is designed and documented to meet high purity demands in industries like biopharmaceutical and personal care. The LKB UltraPure is available with specifications that are preferred by high purity in dusty. The UltraPure version offers an additional set of options for material, end connection, surface finish, and more. UltraPure equipment is available with Alfa Laval's Q-Doc documentation package.
Legacy Valves
Prior to the introduction of the LKB series, Tri-Clover (now Alfa Laval) produced the A51, B51, and B53 models of butterfly valves. The LKB series has replaced these legacy models for all butterfly valve applications. While these valve models are no longer manufactured, many OEM spare parts are still available. See Parts Lists below for details.
