The D4 Hygienic Double Seat Mix Proof Valve from SPX Flow

The SPX D4 Hygienic Double Seat Mix Proof Valve

SPX FLOW is pleased to introduce the hygienic D4 double seat, mix proof valve series. The D (for double seat) valve is used for the reliable separation of dissimilar fluids such as process and CIP solutions. These next-generation valves help fulfill today's customer demands for process flexibility, increased productivity, rapid return on investment, and improved product quality.

The D4 series provides multiple options including non-seat lift, seat lift and ultra hygienic.  This series has high value with low life cycle costs which include:
Reduced inventory costs

• Low chemical and water loss consumption
• Low air consumption and air supply requirements
• Long housing ports to ease manifold building

The lightweight D4 series also makes routine maintenance and handling easy.  These valves are suited for a variety of applications such as milk, soft drinks, dressings, soups, brewing, wine, cleaners and extracts.

Pinch Valves Provide Superior Performance and Low Total Cost of Ownership for Lime Slurry

Calcite Limestone

Lime is a basic industrial chemical that has widespread use in many chemical processes. It is also used extensively in food and beverages production processes. Examples of chemical industry applications are the manufacture of caustic soda (sodium hydroxide), the production of acetylene, the production of the fertilizer calcium cyanamide, the purification of citric acid, the production of pool chlorine, and the making of road de-icing chemicals. Examples of lime use in the food and beverage industry are the production of sugar, the processing of milk and cream, the production of baking powder, the ripening and storage of fresh fruits and vegetables, and the production of corn tortilla's.

Lime is normally stored as a dry powder and mixed with water or additional chemicals to create a lime slurry that can be pumped through pipes and added to the production stream as needed. The management of lime slurry to process piping, valves, and instrumentation is challenging because of lime's physical and chemical properties. Lime slurry is slightly abrasive and can be quite corrosive depending upon the other chemicals involved. Lime also has a tendency to build up as scale inside pipes and valves. This scaling can severely inhibit the operation of traditional quarter-turn valves and restrict flow. Another concern is the problem of dewatering, which happens at the point where pressure is shut off. The upstream pressure in the line ahead of a flow control valve will force liquid out of the lime, leaving a very hard, dry plug behind. The plug is hard enough to prevent the opening of a ball, plug, or butterfly valve. A significant maintenance headache occurs when this happens.

Pinch valves in lime slurry service.

Because of their simple, elastomer wetted, cavity-free design, rubber sleeved pinch valves have proven over time to be the best long-term solution for slurries. Pinch valves provide an excellent seal with tight shut-off, and because of their robust & straight-through design, are able to open and close regardless of obstacles in the flow tube. Other benefits making pinch valves ideal for lime slurry use are low maintenance (no bearings, seals or packing), fast opening and closing, self-cleaning and high Cv.

Control Valve
(Red Valve)

Pinch valves are available in 1" through 96" diameters, can be operated manually or via pneumatic or electric actuators, and perform excellently as control valves.

For any abrasive and corrosive service, and particularly for lime slurry service, pinch valves provide an inexpensive flow control solution with superior performance and very low total cost of ownership.
