Ball valve kfa² 2" threaded gas connection model 730-110-50

Threaded ball valve kfa² 2" threaded gas connection model 730-110-50 is a quarter-turn on/off valve designed for gas installations with 2" (inch) threaded pipe connections. Intended for inline installation, the valve isolates sections of piping to allow maintenance, repair or emergency shutoff. The compact ball mechanism provides reliable sealing and straightforward operation suitable for residential and light commercial gas lines where a threaded 2" connection is required.

Advantages

The valve uses a quarter-turn ball mechanism that ensures rapid open/close operation and a tight shutoff. Threaded 2" connections simplify retrofit and replacement in existing threaded piping systems without the need for flanges or additional adaptors. The design supports straightforward maintenance and offers a compact footprint that fits typical gas line routing while delivering consistent flow control with minimal pressure drop.

Suitable for

• Residential gas supply lines with threaded 2" connections
• Light commercial gas installations and branch lines
• Inline isolation for maintenance and emergency shutoff
• Replacement or retrofit in existing threaded gas piping

Key specifications

• Connection type: threaded female/male 2" (inch) pipe threads for inline installation
• Operation: quarter-turn ball on/off mechanism
• Application: designed for gas service in residential and light commercial use
• Installation orientation: inline, suitable for horizontal or vertical pipe runs depending on system layout
• Sealing: ball valve seating designed to provide tight shutoff for gas isolation

How to use

Install the valve inline by threading it into the corresponding 2" threaded pipe fittings, ensuring proper thread sealant or tape compatible with gas applications is used and that joint tightening follows local codes and torque recommendations. Operate the valve by rotating the handle or actuator a quarter turn: parallel to the pipeline for open flow, perpendicular for closed position. Verify tightness and leak-free connections after installation using appropriate gas leak detection methods and follow local safety procedures before placing the system into service.

Usage recommendations

Use only thread sealants approved for gas applications and perform pressure and leak tests according to applicable standards. Periodically inspect the valve for signs of wear, external damage or leakage and exercise the valve occasionally to prevent sticking. For installations subject to vibration or thermal cycling, ensure mounting and piping supports reduce mechanical stress on threaded joints.
