Ball Valve welded ends - 3 pcs full bore ball valve socket weld ANSI B 16.11 - 2027 | Genebre

Genebre 2027 socket-weld ball valve

The Genebre 2027 is a three-piece, full-bore ball valve with socket-weld ends to ANSI B16.11. The body is stainless steel CF8M / 316. Standard soft parts are PTFE + 15% glass fibre seats and seals with a Viton stem O-ring. Pressure rating is PN63 / 1000 WOG, with a temperature range of -25°C to +180°C, subject to pressure derating and media compatibility.

Size range and actuation

Available from 1/4" to 4". The valve includes an ISO 5211 mounting pad for direct actuator installation and a lockable lever arrangement for manual isolation service.

Typical applications

• permanent welded pipework in small and medium bore lines
• industrial water, utility services and clean process fluids
• compressed air and inert gas distribution
• skid-mounted process packages
• drain, vent, bypass and sampling lines

Suitable media

• water, glycol mixtures and compatible utility fluids
• compressed air, nitrogen and other non-reactive gases
• compatible chemicals where CF8M, PTFE/GF and Viton are acceptable

Engineering selection notes

Socket-weld construction is normally selected where a compact, welded end connection is required and threaded joints are not preferred. The three-piece body permits access to the centre section for seat and seal maintenance, provided the pipework layout allows bolt removal and body swing-out or extraction.

Before selection, confirm CF8M corrosion resistance, PTFE/GF seat suitability, Viton compatibility, pipe schedule, weld procedure requirements, pressure, temperature, cycling frequency and expected leakage class for the service.

Standards and interfaces

• Socket-weld ends: ANSI B16.11
• Actuator interface: ISO 5211
• Pressure class: PN63 / 1000 WOG

Variant comparison

• Socket-weld version: used for permanent welded installations with reduced external leakage points.
• Threaded or flanged variants: easier removal from the line, but with different installation envelope and jointing requirements.
• Manual or actuated operation: manual lever for isolation; pneumatic or electric actuator where remote on/off control is required.

FAQ

Can it be used for throttling?
It is primarily an isolation valve. Continuous throttling may damage soft seats and increase leakage.

Is it suitable for steam?
Only after checking pressure-temperature limits and seat/O-ring compatibility. PTFE and Viton may restrict steam service.

What must be checked before welding?
Pipe schedule, alignment, WPS/PQR, heat input, cleaning, and protection of seats and seals during welding.
