Fully lined ball valves are specialized industrial valves designed for handling corrosive and abrasive fluids. Their key features include a full port design for unrestricted flow, two-piece bolted construction for durability, and complete lining of all wetted parts with materials like PTFE, FEP, or PFA. These valves offer low torque operation, easily replaceable seats, and protection against liner blowout, making them ideal for demanding chemical processing applications where contamination prevention and long-term reliability are critical.
Key Points Explained:
-
Full Port Design
- Provides unrestricted flow with minimal pressure drop
- Matches pipe diameter for efficient fluid transfer
- Reduces turbulence and potential for particle accumulation
-
Two-Piece Bolted Body Construction
- Offers superior structural integrity compared to single-piece designs
- Allows for easier maintenance and inspection
- Provides better sealing performance under varying pressures
-
Complete Lining System
- All wetted parts (body, ball, seats) lined with corrosion-resistant materials like PTFE, FEP, or PFA
- Prevents metal contact with process media
- Uniform lining thickness prevents liner blowout or collapse
-
Integral Ball-Stem Unit
- Ensures precise alignment and smooth operation
- Reduces potential leak paths
- Provides consistent torque characteristics throughout valve life
-
Low Torque Manual Operation
- Lever operation requires minimal force
- Quarter-turn actuation for quick opening/closing
- Suitable for frequent cycling applications
-
Easily Replaceable Seats
- Extends valve service life
- Reduces maintenance downtime
- Allows for cost-effective repairs instead of full valve replacement
-
Pressure-Resistant Design
- Reinforced lining structure withstands system pressures
- Prevents liner deformation or failure
- Maintains seal integrity across temperature fluctuations
-
Chemical Compatibility
- PTFE/FEP/PFA lining resists virtually all industrial chemicals
- Suitable for aggressive media including acids, bases, and solvents
- Non-stick surface prevents material buildup
-
Hygienic Properties
- Smooth lined surfaces prevent bacterial growth
- Easy to clean and sterilize
- Ideal for pharmaceutical and food processing applications
-
Versatile Mounting Options
- Can be panel-mounted for space-constrained installations
- Adaptable to various piping configurations
- Available in multiple end connection types
These features combine to create valves that offer exceptional longevity, reliability, and safety in critical fluid handling applications, particularly where chemical resistance and contamination prevention are paramount concerns.
