LFB Series Low-Temperature Ball Valves
LFB low-temperature ball valves are designed with materials selected for applications requiring temperature ratings from -40 to 200°F (-40 to 93°C), pressure ratings up to 6000 psig (414 bar), and flow coefficients up to 13.8.
Design
1. FLOATING BALL DESIGN
- Upstream pressure assists sealing against the downstream seat
2. LIVE-LOADED SEATS
- Improve sealing in high, low and dynamic pressure and flow conditions
- Fully supported seats improve cycle-life
- PEEK seats for chemical compatibility and durability
3. END SCREW CONSTRUCTION
- Wide variety of end connection type and size combinations
- Three tube fitting designs
- Easy maintenance
4. ROBUST BODY SEALS
- Leak-tight envelope
5. STEM BEARING AND O-RING STEM SEAL
- Leak-tight seal
- Low actuation torque
- No need for packing adjustments
6. DURABLE DIRECTIONAL HANDLE
- Stainless steel reinforced nylon handle for durability
- Indicates flow direction
- Large ergonomic handle for easier actuation
Applications
FB Series ball valves are very versatile. They can be used in both high and low pressure instrumentation systems, process lines, utility systems, and other applications. Designed for higher pressures than many floating ball valves, they can be used in applications such as high-pressure CNG filling station supply lines, equipment and in instrumentation and control systems. Unlike many floating ball designs, FB Series valves are also suitable for low and dynamic pressure conditions. In addition, end-screw construction allows users to specify a wide variety of end connection size and type combinations.
