In food and beverage manufacturing, valves are vital production components as they regulate flow, control pressure, and allow ingredients to move safely and precisely through every stage.
First, we’ll take an in-depth look at the most common valve types used across food and beverage operations, then run through which type of food and beverage production line can benefit from certain types of valves. At FCX Performance, valves are our specialty, and our goal here is to help manufacturers understand the roles and strengths of each valve type.
Here are the most common valves you’ll see in food and beverage production.
Sanitary Diaphragm Valves
The Job of Sanitary Diaphragm Valves
These valves use a flexible diaphragm to isolate the product from moving parts. Due to their precise nature, they’re often used in production lines where absolute hygiene is required, including baby food, pharmaceutical-grade beverages, or biotechnology processes within food production.
Benefits of Sanitary Diaphragm Valves in Food and Beverage
-
Zero contamination risk: No contact between product and valve stem.
-
Reliable sealing: Ideal for sterile and aseptic applications.
-
Easy maintenance: Diaphragm replacement is quick and inexpensive.
-
Precise control: Performs well with viscous or shear-sensitive fluids.
Sanitary Ball Valves
The Job of Sanitary Ball Valves
The full-bore design of a sanctuary ball valve minimizes product restriction, making it ideal for liquids with suspended solids or particulates.
Benefits of Sanitary Ball Valves in Food and Beverage
-
Cleanability: Minimal crevices for residue buildup.
-
Quick shutoff: Provides tight sealing to prevent leaks.
-
Robust design: Handles high-pressure or abrasive fluids.
-
CIP/SIP compatible: Withstands cleaning and sterilization cycles.
Check Valves
The Job of Check Valves
Check valves, or non-return valves, are important to clean operations in processing because they allow fluids to flow in only one direction, preventing backflow that could contaminate clean product streams or damage processing equipment.
Benefits of Check Valves in Food and Beverage
-
Contamination prevention: Maintains separation between product and cleaning media.
-
Low maintenance: Simple design with few moving parts.
-
Versatile: Suitable for liquids, gases, or steam.
-
Reliability: Protects pumps and pipelines from reverse pressure.
Control Valves
The Job of Control Valves
Control valves regulate the flow, pressure, or temperature of process fluids. They are essential in applications requiring precise dosing, mixing, or temperature consistency.
Benefits of Control Valves in Food and Beverage
-
Enhanced accuracy: Maintain steady process parameters, critical for taste and texture consistency.
-
Reduced waste: Prevents overfilling or product loss during transfer.
-
Flexible operation: Works with liquids, semi-solids, or gases.
-
Integration ready: Can connect with digital process control systems for data-driven adjustments
Knife Gate Valves
The Job of Knife Gate Valves
Knife gate valves use a sharp-edged blade to cut through thick or viscous fluids. They are commonly used in applications like fruit purees, dough, or other dense mixtures where standard valves might clog.
Benefits of Knife Gate Valves in Food and Beverage
-
Dependable flow control: Designed for slurry and paste-like materials.
-
Ease of cleaning: Their open design allows for thorough washdowns.
-
Compact footprint: Can fit into tight process layouts.
-
Durability: Handles fibrous or chunky materials without jamming
Lined Butterfly Valves
The Job of Lined Butterfly Valves
Lined butterfly valves feature a disc that rotates to regulate flow, with a corrosion-resistant lining such as PTFE or EPDM. In systems where both hygiene and chemical resistance are required, lined butterfly valves shine.
Benefits of Lined Butterfly Valves in Food and Beverage
-
Chemical resistance: Ideal for cleaning agents or acidic ingredients.
-
Lightweight and economical: Simple design reduces installation costs.
-
Fast operation: Quick quarter-turn control.
-
Hygienic design: Smooth linings prevent buildup and are easy to sanitize.
Safety Relief Valves
The Job of Safety Relief Valves
Conventional spring safety relief valves protect equipment and personnel by releasing excess pressure when things start to get a little “too hot” and safe operating limits are passed.
Similar to the role of steam condensate pumps, which we discuss in our post on commonly used pumps in the food and beverage industry, these types of valves are therefore essential for things like steam systems, pressure vessels, and pasteurization lines.
Benefits of Safety Relief Valves in Food and Beverage
-
Equipment Protection: Prevention of overpressure damage in tanks and pipelines.
-
Compliance: Allows companies to meet safety standards for pressure control systems.
-
Automated Design: Spring-loaded design ensures quick, automatic response.
Take the steam out of pressure spikes: Businesses can avoid costly system failures that threaten to take operations down.
Sanitary Butterfly Valves
The Job of Sanitary Butterfly Valves
These valves use a rotating disc to open or close the flow path, balancing flow control with low weight and easy cleaning. They are more commonly applied in beverage production, in lines that focus specifically on dairy, soft drinks, edible oils and brewing applications.
Benefits of Sanitary Butterfly Valves in Food and Beverage
-
Simplistic style of operation: Quick to open and close.
-
Compact and cost-effective: Low maintenance and long service life.
-
Hygienic: Designed for sanitary pipelines with polished stainless steel surfaces.
Valve Automation
The Job of Valve Automation
Valve automation systems use actuators, sensors, and controllers to operate valves remotely or automatically. In food facilities, automation allow flow and pressure adjustments happen accurately and consistently, without manual intervention.
Automation is used regularly in things like bioreactors, fermentation tanks, and bottling/filling lines.
Benefits of Valve Automation in Food and Beverage
-
Precision control: Enables exact flow rates and repeatable processes, essential for batching and blending.
-
Improved hygiene: Reduces human contact with product zones.
-
Productivity gains: Automated systems minimize downtime and human error.
-
Traceability: Integration with process control systems allows for full production monitoring.
