The full-flow body design of Alfa Laval’s Ball Valves enable the product to pass through the valve with no restrictions and with a minimal pressure drop. The basic design allows cleaning and product recovery using pigging systems, and they are ideal for use with viscous liquids and liquids containing solid or semi-solid particles. Alfa Laval ball valves for hygienic use bear the Alfa Laval SBV and Alfa Laval Tri-Clover® designations.

5308/5309 Series Ball Valve

Alfa Laval 5308/5309 Series Ball Valves are designed for use as a product valve, and are available with pneumatic actuators or manually-operated handles. Ideal for applications that involve high operating pressure and temperatures as well as where the use of pigging systems is required.

These ball valves are dependable and versatile valves, ideal for applications which require a full-flow body design to minimize line turbulence and pressure drop. They are also known for their reliability and easy maintenance, and they are an economical drop-in replacement for the Tri-Clover 4300 series.

The 5308 (Tri-Clamp® connections) and 5309 (butt weld connections) valves are available in seven sizes, with pneumatic actuators or manually operated handles. An optional encapsulated seat reduces the risk of product entrapment.

Reliable full-flow performance

Alfa Laval 5308/5309 Series Ball Valve are full-bore flow valves that provide on/off control with minimal pressure drop. The valve opening has a constant pipeline diameter, which enables fluids to flow freely through the valves when open. Flow restriction is comparable to that of a straight tube. This makes the valve suitable for:

  • Handling fluids that are viscous or contain solid, semi-solid or abrasive particles
  • Use wherever pigging of process lines is a major consideration
  • Applications that require gentle product treatment
  • CIP applications

Compact, simple ball valve design

Easy to build into most any process line, Alfa Laval 5308/5309 Series Ball Valve feature a straightforward floating ball design, which guarantees a tight seal and permits axial movement while preventing rotation. They are water hammer-safe and completely insensitive to pressure shocks in the pipelines.

Easy-to-maintain ball valves

The three-piece valve design with few moving parts enables easy access to all valve components, making maintenance quick and easy. Durable PTFE valve seats help prolong service intervals. No special tools required for maintenance.

Hygienic ball valve range

The Alfa Laval hygienic ball valve range consists of two standard valve models.

  • SBV with either manual handle or automated operation for applications that involve high operating pressures up to 16 bar and temperatures up to 150°C, and where the use of pigging systems is required.
  • Tri-Clover® ball valves for applications that require full flow with minimal flow turbulence and pressure drop. An optional encapsulated seat is available for applications where reducing the risk of potential product entrapment is important.

Construction

The Alfa Laval 5308/5309 Series Ball Valve consists of a valve body, two flanges, PTFE valve seats, ball, stem unit and a handle for manual operation. For quick and easy inspection and maintenance, the valve easily assembles and disassembles with welded-end flange screws.

Operating principle

A precision-made ball with a bore, or opening, is positioned inside the valve body between two flanges and two PTFE valve seats.

Options

  • Quarter-turn handle for manual operation
  • Fittings in accordance with required standard (ISO or DIN)
  • PTFE encapsulated valve seats
APPLICATIONS

5308/5309 Series ball valves are suited for a variety of applications. Sanitary ball valves are the go-to valve for applications like water, air, and ingredient lines, where reliability and ease of maintenance are priorities. The full-bore design is ideal for handling viscous fluids or fluids with solids or semi-solid particles while minimizing turbulence and pressure drop. A constant inner diameter allows for free fluid flow and even allows for the use of product recovery projectiles.

STANDARD DESIGN

The Tri-Clover 5308/5309 ball valve consists of a stainless steel body that houses a rotating ball. The rotating ball is sealed in the body with a PTFE seat that either partially or fully encapsulates the ball. The valve is activated by a stainless steel handle that opens and closes the valve through a quarter turn. The valve can also be operated by an optional ¼ turn pneumatic actuator. External thrust springs maintain constant pressure on the stem packing. The stem and packing design eliminate the possibility of the stem becoming dislodged or blown out.

The 5308/5309 valve is available in seven end connection sizes: ½, ¾, 1, 1½, 2, 3, and 4 inch. Both Tri-Clamp (model 5308) and butt weld (model 5309) connections are available.

SBV Sanitary Ball Valve

Reliable full-flow performance

Alfa Laval sanitary ball valves (SBVs) are full-bore flow valves that provide on/off control with minimal pressure drop. The valve opening has a constant pipeline diameter, which enables fluids to flow freely through the valves when open. Flow restriction is comparable to that of a straight tube. This makes the SBVs suitable for:

  • Handling fluids that are viscous or contain solid, semi-solid or abrasive particles
  • Use wherever pigging of process lines is a major consideration
  • Applications that require gentle product treatment
  • CIP applications

Automated or manual control

For versatility, Alfa Laval SBVs can be supplied for manual or automatic operation.

Manual operation: SBVs feature stainless steel quarter-turn handles to mechanically lock the valves in either open or closed position.

Automatic operation: SBVs use standard maintenance-free pneumatic actuators. Actuated ball valves are delivered as normally closed (NC) valves that are controlled from a remote location by means of compressed air. These, however, can easily be rebuilt to a normally open (NO) configuration. Actuators can be fitted with Alfa Laval ThinkTop valve sensing and control units. Optional inductive proximity sensor and mounting bracket are available.

Compact, simple ball valve design

Easy to build into most any process line, Alfa Laval SBVs feature a straightforward floating ball design, which guarantees a tight seal and permits axial movement while preventing rotation. They are water hammer-safe and completely insensitive to pressure shocks in the pipelines.

Spring-loaded, self-adjusting seal rings provide highly reliable valve stem sealing. SBVs with automated control have inspection holes in the bonnet for easy inspection of the stem seal.

Construction

The Alfa Laval SBV sanitary ball valve consists of a valve body, two flanges, PTFE valve seats, ball, stem unit and either a handle for manual operation, or a bonnet and pneumatic actuator for automated operation. For quick and easy inspection and maintenance, the valve easily assembles and disassembles with welded-end flange screws.

Operating principle

A precision-made ball with a bore, or opening, is positioned inside the valve body between two flanges and two PTFE valve seats.

Options

  • Quarter-turn handle for manual operation or pneumatic actuator for automated operation
  • Bracket for mounting inductive proximity switches
  • ThinkTop® valve sensing and control unit
  • Fittings in accordance with required standard (ISO or DIN)
  • PTFE encapsulated valve seats
  • Valve seat cleaning connections
  • O-rings in NBR, Q (Silicone), FPM (Viton)

Concept

SBV is a hygienic ball valve designed for use as a product valve, in
applications within food, beverage, pharmaceutical and chemical
industries. The full bore design with zero flow restriction makes SBV
the optimum choice for viscous or particulate liquids.

Working principle

A precision made ball with a bore is positioned inside the valve body
between two flanges and two PTFE valve seats. A 90° rotation of the
valve stem is transferred to the ball and thereby opening or closing the
valve. A special selected PTFE material grade secures long lifetime of
the product wetted seals. Reliable valve stem sealing is achieved by
the use of spring loaded and self adjusting seal rings. SBV is operated
by a pneumatic actuator or manually operated by means of a handle
with lockable positions. The valve is assembled with screws for easy
inspection and maintenance.

Standard Design

The standard actuator is prepared for position indication with inductive
proximity switches. The actuator is maintenance free. Two inspection
holes in the bonnet connecting valve body and actuator allow for easy
inspection of the stem seal tightness. Actuated valves are delivered
NC (normally closed) and are easily rebuild to NO (normally open).
