Ball Valve welded ends - 3 pcs full bore ball valve socket weld ANSI B 16.11 - 2034S | Genebre

Genebre 2034S socket-weld ball valve

The Genebre 2034S is a three-piece, full-port ball valve with socket-weld ends to ANSI/ASME B16.11. The body is carbon steel WCB, with stainless steel 316 ball and stem, PTFE + 15% glass-fibre seats, 1000 WOG pressure rating, and operating temperature range from -25°C to +180°C, subject to pressure-temperature derating and media compatibility.

Sizes, operation and construction

• Nominal sizes: 1/4" to 4"
• Manual operation by lever with locking device
• Three-piece body for access to the centre section during maintenance
• Full-port bore for low pressure drop in open position
• Socket-weld ends for permanent welded installation on carbon steel pipework

Suitable media and operating conditions

• Compressed air and inert gases
• Water and utility circuits
• Mineral oils and compatible hydrocarbons
• Drain, vent, bypass and skid-package piping
• General industrial service where PTFE/GF seats are chemically and thermally compatible

Application notes

Socket-weld construction reduces potential leakage paths associated with threaded joints, but it requires qualified welding procedures. The installation should account for WPS/PQR requirements, heat input control and protection of PTFE-based seats from welding temperature exposure.

The three-piece design allows the centre body to be removed for inspection or seat replacement if sufficient pipework clearance and bolting access are provided during installation.

Comparison with other end connections

• Socket-weld: compact welded joint, suitable for small-bore carbon steel process lines.
• Threaded: easier removal, but more leakage-sensitive under vibration or thermal cycling.
• Flanged: easier line removal, but larger envelope and additional gasketed joints.

Standards and documentation

• Socket-weld ends: ANSI/ASME B16.11
• Pressure designation: 1000 WOG for water, oil and gas service under applicable conditions
• Body material: carbon steel WCB
• Trim material: stainless steel 316 ball and stem
• Material certificates, PED/CE status or project-specific documentation should be verified against the supplied valve datasheet and purchase order requirements.

Actuation and sealing considerations

The standard configuration is lever-operated. For automated service, actuator selection should be based on valve size, differential pressure, operating frequency, available air or electric supply, required fail position and stem torque with safety factor. The standard sealing system is PTFE + 15% glass fibre; alternative seat materials require confirmation against the exact valve variant and process medium.

FAQ

Can the valve be welded with the seats installed?
Heat input must be controlled. Where practical, remove or protect the centre section to prevent thermal damage to PTFE/GF seats.

Is it suitable for steam?
Only if the pressure-temperature rating, seat material and manufacturer data confirm suitability for the specific steam condition.

Why select this valve instead of a threaded ball valve?
Use socket-weld ends where a permanent welded joint is preferred and threaded leakage risk is not acceptable.
