What Are Industrial Valves?
Industrial valves are precision-engineered devices that control, direct, or regulate the flow of fluids (liquids, gases, fluidized solids) by opening, closing, or partially obstructing various passageways.
Key Industrial Applications
- Chemical and petrochemical processing
- Water treatment and distribution systems
- Oil and gas pipeline operations
- Power generation facilities
- Marine and offshore applications
Five Primary Valve Functions
Understanding the fundamental operations that make valves essential in industrial systems.
Complete flow isolation capability - valve provides binary control to either allow media to pass through completely or obstruct flow passage entirely. This fundamental function is critical for system isolation and emergency shutdown procedures.
Advanced directional flow management with multidirectional and multiport capabilities for complex routing applications. Enables sophisticated flow distribution and redirection within piping systems.
Precise pressure level maintenance and adjustment within piping systems to ensure optimal operation. Provides continuous pressure monitoring and automatic adjustment capabilities for system optimization.
Critical safety function to relieve dangerous over-pressure conditions or compensate for vacuum situations. Provides automatic protection against system damage and ensures operational safety standards.
Precise partial opening control allowing exact percentage modulation of media flow through the valve. Enables fine-tuned flow control for process optimization and system efficiency enhancement.
Valve Components & Anatomy
