Applications
The Gearbox LF2 Low Temp PTFE Ball Valve is ideal for:
Cryogenic pipelines: LNG, liquid nitrogen, oxygen, ethane, ethylene.
Sub-ambient fluid systems: Chilled water loops, chemical plants, refrigerated processes.
Slurry and viscous media lines: Where full-bore, minimal restriction flow is required.
Industrial gas processing: Air separation, petrochemical, aerospace ground support.
Pipelines requiring pigging: Full bore design ensures easy cleaning and maintenance.
Key Features
Full Bore Flow Path: The Full Bore Ball Valve design matches the pipeline diameter for maximum flow efficiency, pigging capability, and minimal turbulence.
Low Temperature Design: Engineered to operate reliably in low temp conditions, down to –196 °C (–320 °F) depending on size and material.
PTFE Soft Seats: The PTFE Ball Valve seats offer excellent chemical resistance, low-friction operation, and tight shut-off under sub-zero conditions.
Gearbox Actuation: Compatible with manual gearbox or motorized drive, facilitating smooth operation of large valves where manual torque is challenging.
Robust Construction: Forged or cast stainless steel body suitable for thermal contraction and low-temperature environments.
Versatile End Connections: Available in flanged, butt-weld, socket-weld, or threaded ends.
Low-Emission and Safety Options: Optional live-loaded stem packing, cavity pressure relief, and double-block & bleed designs to reduce fugitive emissions.
Efficient Flow & Energy Saving: The full-bore design ensures minimal pressure drop and unrestricted media flow, ideal for high-volume industrial pipelines.
FAQ
Q1: What is a Full Bore Ball Valve, and why is it important?
A: A Full Bore Ball Valve has an internal port equal to the pipeline diameter, allowing unrestricted flow, reduced pressure drop, and pigging capability.
Q2: Why choose a PTFE Ball Valve for low-temperature applications?
A: PTFE seats maintain sealing integrity under extreme cold, resist chemical corrosion, and reduce friction for smooth operation.
Q3: Can this valve be automated?
A: Yes, the gearbox interface supports manual operation and can be adapted to motorized or pneumatic actuators.
Q4: What sizes and end connections are available?
A: Standard options include flanged (ANSI/ASME), butt-weld, socket-weld, or threaded ends. Size and pressure ratings depend on project requirements.
