THREADED BALL VALVE – CLASS 800

1. Product Overview

Class 800 threaded ball valves are quick shut-off valves operated by rotating the ball 90°. With the Class 800 rating, these valves can withstand operating pressures up to 138 bar (around 2000 PSI), far exceeding conventional cast ball valves (which typically handle only 16–25 bar).

3. Construction and Key Features

• Forged body: Extremely strong metal structure, eliminating risks of porosity or cracking found in cast valves, capable of withstanding strong hydraulic shocks.
• 3-piece design: Common in Class 800 valves, allows removal of the center body for gasket replacement without disconnecting pipe ends.
• Anti-blowout stem: Specially designed stem prevents internal pressure from forcing it out, ensuring operator safety.
• Robust lever handle: Equipped with a locking device to prevent accidental or unauthorized operation.

4. Why Customers Should Choose Class 800 Ball Valves for Fuel/Chemicals

• Extreme pressure resistance: Suitable for high-pressure oil pipelines, hydraulic systems, or compressed gas lines.
• Absolute sealing: Premium seats ensure zero leakage, even with highly permeable fluids such as gasoline or solvents.
• Quick shut-off: 90° lever action provides instant flow isolation in emergencies.
• Fire-safe design: Many models maintain sealing integrity even if soft gaskets are damaged during fire incidents.

5. Practical Applications

• Fuel filling stations: For high-pressure pump lines requiring rapid shut-off.
• Gas and nitrogen systems: High-pressure gas pipelines.
• Chemical plants: Transporting corrosive and high-pressure liquids.
• Hydraulic systems: Used as shut-off valves in hydraulic power units.
