Ball Valve threaded ends - 3 pcs full bore ball valve - 2025 | Genebre

Genebre 2025 three-piece ball valve

The Genebre 2025 is a full-bore, three-piece ball valve with threaded BSP connections to ISO 7-1 / EN 10226-1. The valve body is stainless steel CF8M / 316, with PTFE + 15% glass-filled seats, Viton stem O-ring, PN63 pressure rating and operating temperature range from -25°C to +180°C.

Sizes, connections and automation

• Nominal sizes: 1/4" to 4"
• Threaded ends: BSP ISO 7-1 / EN 10226-1
• Mounting interface: ISO 5211 top flange
• Operation: manual lever or direct mounting of pneumatic/electric actuators
• Lever locking device for isolation duty and controlled access

Suitable media and operating context

• industrial water and utility lines
• compressed air systems
• inert gases
• general process lines
• CIP auxiliary lines, subject to chemical compatibility checks
• skid-mounted packages and locations requiring periodic maintenance access

Valve selection logic

The three-piece construction allows access to the centre body without removing the complete valve assembly from the pipework, provided the installation has sufficient clearance and the pipe supports are correctly designed. This is relevant for maintenance, seat inspection and seal replacement.

The full-bore design reduces pressure drop compared with reduced-bore valves of the same nominal size. Selection should confirm compatibility of CF8M/316, PTFE glass-filled seats and Viton elastomers with the process fluid, pressure, temperature, cleaning chemicals and cycling frequency.

Sealing arrangement

• Ball seats: PTFE + 15% glass fibre
• Stem sealing: Viton O-ring
• Leakage assessment should consider differential pressure, temperature, media viscosity and actuator torque margin

Comparison with other ball valve constructions

• One-piece valves: compact, but limited internal access
• Two-piece valves: common for isolation, with moderate serviceability
• Three-piece valves: better access to the body cavity and seats for maintenance-intensive installations

Standards and verification

Relevant construction features include BSP threading to ISO 7-1 / EN 10226-1 and actuator mounting to ISO 5211. Any project-specific certification, material traceability, pressure test documentation or regulatory approval should be verified against the manufacturer’s datasheet and order documentation.

FAQ

Can the valve be automated?
Yes. The ISO 5211 mounting pad allows direct installation of pneumatic or electric actuators, subject to torque sizing.

Is it suitable for throttling?
It is primarily an isolation valve. Continuous throttling can increase seat wear and should be reviewed case by case.

What are the main selection checks?
Pressure class PN63, temperature range, fluid compatibility, seal material, end connection, actuator torque and maintenance access.
