Ball Valve Wafer type 1 pc full bore ball valve mounting between flanges PN 16 - 2105 | Genebre

Genebre 2105 wafer ball valve PN16

The Genebre 2105 is a wafer-type full bore ball valve for installation between PN16 flanges. The body is ASTM A105 carbon steel, with ball, stem and cap in AISI 304 stainless steel. Seats and seals are PTFE. Stated operating temperature range: -20°C to +180°C, subject to pressure, medium and sealing compatibility.

Installation and operation

The wafer construction reduces face-to-face length compared with a conventional flanged ball valve. The valve is clamped between mating flanges and is normally operated manually by lever. Correct flange alignment and even bolt tightening are important to avoid body stress and external leakage.

Typical applications

• industrial water circuits
• compressed air lines
• utility and auxiliary process services
• HVAC water distribution and plant utilities
• process lines where short installation length is required

Suitable media and operating conditions

Typical services include clean liquids, non-aggressive gases and compatible industrial utilities. Media compatibility must be checked against ASTM A105, AISI 304 and PTFE. For steam, thermal oil, solvents, corrosive fluids or cyclic thermal operation, confirm the allowable pressure-temperature rating and seat suitability before selection.

Standards and material references

• Pressure class: PN16
• Body material: ASTM A105 carbon steel
• Ball, stem and cap: AISI 304 stainless steel
• Soft seats and seals: PTFE
• Flange compatibility: verify mating flange standard, gasket type and bolt length

Selection logic

Selection should verify pressure class, temperature, medium, corrosion allowance, flange compatibility and leakage requirements. The full bore design gives lower pressure drop than reduced bore valves, which is relevant in utility headers and pump discharge or return lines.

Variants and actuator options

• Wafer vs flanged: wafer valves save axial space but depend on correct flange clamping.
• Full bore vs reduced bore: full bore is preferred where pressure loss or pigging access is a concern.
• Manual operation: lever operation is standard for local isolation.
• Automation: if pneumatic or electric actuation is required, confirm torque, mounting interface and stem dimensions from the manufacturer data sheet.
• Sealing: PTFE is the standard sealing material; alternative seats must be selected only after checking media and temperature limits.

Maintenance considerations

Soft-seat ball valves are generally used for on-off isolation, not throttling. Frequent partial opening can damage the seats and increase internal leakage. During maintenance, check stem sealing, flange gasket compression, handle travel stops and seat leakage under the specified test conditions.

FAQ

Is the Genebre 2105 suitable for control duty?
It is primarily an isolation valve. For modulating control, use a control valve or a characterized ball valve selected for the required flow coefficient and actuator duty.

Can it be used on steam?
Only after checking the pressure-temperature limits, PTFE seat rating and manufacturer approval for the specific steam condition.

What must be checked before procurement?
DN size, PN16 flange compatibility, material compatibility, temperature range, pressure rating, leakage class expectations, manual or automated operation, and required documentation or certificates.
