Quick Links

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.
