Ball valve UltraPure quality

The valve range consists of hygienic full-bore ball valves that combine reliable, full-flow performance and economical on/off control with minimal pressure drop.

With a straightforward, low-maintenance design, these valves consistently provide a high flow rate through an unobstructed flow path, making them the ball valve of choice for flow control in most hygienic fluid-handling systems.

For dairy, food and beverage, and high-pressure applications, Alfa Laval also offers the traditional Sanitary ball valve.

UltraPure ball valve design

The Ball valve UltraPure comes with several features that ensure dependable hygienic performance.

Advanced PTFE seal

Alfa Laval’s superior PTFE seal technology provides greater thermal stability, better chemical resistance and improved tensile strength.

Surface finishes

Ball valve UltraPure is available with Ra < 0.5µm surface finish to ensure cleanability and minimize contamination risks.

Weld ends and clamp ends

To meet hygienic welding requirements, Ball valve UltraPure features ASME BPE, ISO 2037 and Series A/DIN weld ends and ASME BPE clamp ends.

Standard encapsulated seat

The seat reduces the risk of potential product entrapment in applications where hygiene is critical.

Complete product range

The Ball valve UltraPure range comprises ASME BPE, DIN 11850 and ISO 2037 models in a full range of dimensions. The valves have a maximum operating temperature of 150°C and maximum operating pressure of 40 bar. The range is readily available with short delivery times.

High quality, well documented

Equipment and components in the  UltraPure 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 UltraPure equipment supply and provides customers with transparent and well-documented quality assurance of the sourced equipment.

Concept

Ball Valve UltraPure is ideal for applications requiring a full flow body design to minimize line turbulence and pressure drop. Seat with cavity filler is standard offering for critical process applications requiring minimum risk for product entrapment.

Standard Design

The Ball Valve UltraPure consists of a stainless steel body that houses a rotating ball. The rotating ball is sealed in the body with a PTFE seat that fully encapsulates the ball. The valve is activated by a stainless steel handle that opens and closes the valve through a quarter turn. External thrust springs maintain constant pressure on the stem seal. The stem seal design eliminates the possibility of the stem becoming dislodged or blown out.

Construction

The valve consists of a 316L (CF3M9) steel valve body, PTFE valve seats, rotating ball, stem unit and stainless steel quarter-turn handle, stainless steel handle for manual operation, bushings for the disc stem and seal ring.

Operating principle

A precision-made rotating ball with a bore, or opening, is positioned inside the valve body between two flanges and two PTFE valve seats. To open or close the valve, manually rotate the handle by 90° to turn on or shut off the flow. External thrust springs maintain constant pressure on the stem seal. The robust design of the stem and seal eliminates misalignment and blowout.
