Applications
VB3, VB3X series ball valves with lowest dead volume is required in analytical purpose to prevent fluid entrapment which can cause contamination.
Sour Environment Services
UNILOK valves are comply with NACE MR-0175/ISO 15156 for sour oilfield application or NACE MR-0103 for petroleum refining operations. To order, add-N to the end of part number.
Testing
Each valve undergoes 100% factory testing with air and nitrogen at 1000 psig (69 bar) to check for seat and packing leakage. Each test is conducted with a maximum allowable leak rate of 0.1 scc/min.
Cleaning
UNILOK valves are free from machine oils, loose particles and grease throughout the close cleaning process.
The special cleaning for high purity application is available upon request.
Important Notification
UNILOK ball valves are designed to be operated in a fully open or fully closed position.
The packing adjustment may be required during the valve’s service life.
Proper installation, materials compatibility, operation and maintenance of these valves are the responsibility of the user. The total system design must be taken into consideration to ensure optimal performance and safety.
Features
The pressure rating for valves with a 4.8 orifice and standard PTFE seats is 3000 psig (206 bar)
For other valves, the pressure rating is 2500 psig (172 bar)
The temperature rating, with standard PTFE packing, ranges from 10 ℃ (50 ℉) to 65 ℃ (150 ℉)
The compact one-piece design minimizes space requirements and potential leak points.
The one-piece integral ball stem eliminates backlash and ensures perfect encapsulation of ball seats.
Designed for panel mounting to facilitate easy installation.
