Inox-val 2 Piece Ball Valves - 701000 | Valpres

Valpres 701000 Ball Valve

Two-piece stainless steel ball valve in A351 CF8M for shut-off duty on threaded liquid and gas lines. The valve is intended for isolation service, not for continuous throttling or control regulation.

Technical Data

• Sizes: 1/8” to 4”
• Pressure rating: PN140 up to 1/2”, PN105 up to 1”, PN64 up to 2”, PN25 up to 4”
• Temperature range: -20°C to +160°C
• Vacuum service: down to 10⁻² torr
• Body and end connection: A351 CF8M stainless steel
• Ball: A479 TP316 or A351 CF8M
• Stem: A479 TP316 / 17-4PH
• Seats and seals: PTFE
• O-ring: FKM
• Handle: AISI 316 stainless steel

Media and Operating Conditions

Suitable for water, compressed air, neutral gases, utility services and chemical liquids compatible with CF8M stainless steel, PTFE and FKM. For solvents, acids, caustics or elevated-temperature service, chemical compatibility and pressure derating must be checked before selection.

Standards and Certifications

• TÜV-certified executions available
• ATEX and fire-safe executions available on request
• Pressure class must be verified against DN, temperature and fluid category

Variants and Selection Notes

• Standard version: manual lever-operated isolation valve for threaded process and utility lines.
• TÜV version: used where third-party certification is required by plant specification.
• ATEX / fire-safe version: selected for hazardous areas or services requiring defined fire response criteria.

Actuation and Sealing

The standard configuration is manual quarter-turn operation with a stainless steel lever. Where remote operation is required, actuator compatibility, stem torque, mounting arrangement and cycle frequency should be confirmed with the valve configuration. PTFE seats provide chemical resistance and low operating torque; FKM O-rings must be checked for compatibility with the process fluid and temperature.

Typical Applications

• Industrial water and compressed air headers
• Neutral gas distribution
• Chemical utility lines
• Skid-mounted equipment and package units
• Maintenance isolation upstream or downstream of instruments and equipment

FAQ

Can it be used for throttling? It is primarily an isolation valve. Part-open operation may increase seat wear and leakage risk.

What must be checked before ordering? DN, PN rating, thread type, temperature, media compatibility, certification requirement and actuator need.

Is it suitable for vacuum? Yes, down to 10⁻² torr, provided the full assembly and end connections are compatible with the service.
