These butterfly valves are hygienic on/off valves for use with low and medium-viscosity liquids in personal care, biotech and pharmaceutical applications.
Based on the well-known Alfa Laval LKB valve platform, our LKB UltraPure butterfly valve range is a competitively priced alternative to diaphragm valves. Designed for use in high purity applications, the range consists of easy-to-configure units designed to meet the full spectrum of requirements for hygienic applications.
A full range of dimensions (ASME BPE, DIN 11850 and ISO 2037) is available.
For dairy, food and beverage, and high-pressure applications, Alfa Laval also offers the traditional LKB butterfly valve.
LKB UltraPure butterfly valves come with several features that ensure dependable hygienic performance.
LKB UltraPure butterfly valves can be complemented either with:
Equipment and components in the Alfa Laval BioPharm portfolio are supplied with Alfa Laval Q-doc, a comprehensive documentation package that provides full transparency of the entire supply chain, from raw material to final equipment delivery. This smoothes purchasing and installation procedures as well as facilitates qualification, validation and change control procedures. Based on GDP (Good Documentation Practice), Alfa Laval Q-doc covers every aspect of biotech and pharmaceutical equipment supply and provides customers with transparent and well-documented quality assurance of the sourced equipment.
The Q-doc package for LKB UltraPure butterfly valves comprises equipment manuals, performance tests, quality and manufacturing procedures, material certificates, traceability of product wetted parts and the necessary parts and service information. This attention to detail maximizes uptime and minimizes risk.
The valve consists of two valve body halves, valve disc, bushings for the disc stem and seal ring. The valve is assembled by means of screws and nuts.
The standard Tri-Clover LKB UltraPure butterfly valve range is designed either for automatic or manual operation.
The automated LKB UltraPure butterfly valve is controlled from remote location by means of compressed air using a pneumatic actuator. The actuator controls the axial movement of a piston, which rotates the shaft 90°. The torque exerted by the actuator increases when the valve disc contacts the valve sealing ring, to ensure effective closing. The actuator is available in three standard versions: normally closed (NC), normally open (NO) and air/air activated (A/A).
The Tri-Clover LKB UltraPure butterfly valve is controlled manually by means of a handle. The handle mechanically locks the valve in its open or closed position. A two-position, four-position, regulating 90° or lockable multi-position handle is available. The handle is fitted on to the valve by means of a cap/block system and a screw and can be supplied with either welding or clamp connections.
