Ball valve gas, 3" FF - lever

Product detailed description

This ball valve is typically used in industrial gas distribution systems such as boiler feed lines, gas metering stations and process plant piping. It ensures tight shut-off and low-pressure drop due to its full-bore design. The nickel-plated brass construction provides resistance to corrosion and mechanical wear in environments exposed to atmospheric conditions. Installers working on gas supply networks will find this valve suitable for manual isolation of flow in dry gas systems.

The valve is commonly found in commercial and light industrial buildings where gas is supplied through fixed piping infrastructure. It is often part of larger gas control systems that require durable, reliable shut-off without frequent actuation. The internal female threads allow direct mounting onto pipe ends prepared with matching male fittings, eliminating the need for additional adapters or unions in many standard configurations.

Technical parameters

Installation and connection

To install the valve, align the female threads with the corresponding male pipe ends. Apply a suitable sealing compound or PTFE tape to the threads before tightening evenly using a spanner. Ensure the lever handle is positioned for easy access after installation. Check that the valve is fully closed during the tightening process to prevent internal seat damage.

Compatibility and accessories

This valve is compatible with standard gas pipelines using 3-inch FF threaded connections. For installation, ensure that the adjacent piping components also feature matching male threads. Additional items such as pipe clamps or supports may be required depending on the system layout. No specific accessories are mandatory unless the application involves expansion joints or pressure regulators.

Technical background for designers

The ball valve operates by rotating a solid metal sphere inside the body, which either aligns or blocks the flow path. The nickel-plated brass CW617N material provides durability and resistance to corrosion while maintaining structural integrity under pressure. The full-port design minimises turbulence and pressure loss in the system. The lever handle allows for manual operation without requiring tools. Designers should account for the valve’s nominal size when calculating pressure drops and ensuring sufficient clearance for maintenance access.

Service and operation

Periodic visual inspections are recommended to identify signs of external corrosion or mechanical damage. Ensure the lever moves freely without excessive force, indicating possible internal fouling or seat wear. No scheduled maintenance is specified in the provided data. If leakage occurs, disassemble the valve carefully and inspect the sealing surfaces and O-rings for wear.

Frequently asked questions

Can the valve be used for water systems?
Yes, the valve is suitable for water applications at PN 40 and temperature range -30°C to +120°C, according to the manufacturer’s specifications.

Is the valve suitable for high-pressure gas applications?
No, the maximum pressure rating for gas is PN 5. For higher pressures, alternative models must be selected based on system requirements.

How does the nickel plating affect performance in corrosive environments?
The nickel plating enhances resistance to oxidation and atmospheric exposure, making the valve suitable for outdoor or semi-industrial installations.
