PN63 Full Bore Ball Valve for Gas Networks Type 2001 IMF-S/SN

Type 2001 IMF-S/SN is a full bore isolation ball valve for natural gas, LPG and industrial gas services. It is selected where PN63 pressure rating, low pressure drop and controlled seat/stem leakage are required in distribution, transfer or process gas lines.

Construction and Materials

• Forged or cast steel body, suitable for higher mechanical loads
• Precision-machined stainless steel ball
• Anti blow-out stem arrangement
• Reinforced PTFE or gas-compatible polymer seats
• Anti-static device for conductive continuity between ball, stem and body
• Lockable manual operating position

The full bore design keeps the internal flow area close to the pipeline bore and reduces permanent pressure loss across the valve.

Pressure Class and Operating Conditions

• Nominal pressure: PN63
• Quarter-turn operation: 0–90° open/closed position
• Temperature range: dependent on seat material, elastomers and gas composition

Final selection shall consider design pressure, operating temperature, pressure cycling, shut-off class, venting requirements and compatibility of soft sealing materials with the gas phase.

Standards and Certifications

• PED 2014/68/EU, where applicable
• CE marking, according to scope
• ATEX suitability for potentially explosive atmospheres, when specified
• EN 13774 or equivalent gas valve standards
• ISO 5211 actuator mounting interface, when provided

Suitable Media

• Natural gas
• LPG
• Biogas, subject to H₂S and condensate content
• Inert gases
• Compressed air
• Industrial process gases

Actuation and Control Options

• Manual lever or gearbox, depending on size and torque
• Pneumatic actuator
• Electric actuator
• Limit switches for open/closed feedback
• Solenoid valve for pneumatic control
• Remote position monitoring for gas safety systems

Variant Considerations

IMF-S/SN variants may differ by end connection, body execution, sealing package, actuator interface or certification scope. Datasheet verification is required before procurement, especially for gas approval, flange drilling, face-to-face length and fugitive emission requirements.

Typical Applications

• Medium and high pressure natural gas networks
• Gas pressure regulating and metering stations
• LPG distribution lines
• Industrial burners and combustion skids
• CHP plants and energy installations
• Food, chemical and metal processing utilities using fuel or technical gases

Leakage and Maintenance Notes

Gas service requires controlled internal seat leakage and low external leakage at the stem. Anti-static design, anti blow-out stem retention and compatible packing materials are relevant safety features. Periodic inspection should include stem packing condition, actuator travel, locking device function and verification of open/closed indication.

FAQ

Why specify PN63 for a gas valve?

PN63 is used when system design pressure, transient pressure or safety margin exceeds the capability of lower pressure classes.

Is it suitable for natural gas?

Yes, provided the selected valve size, sealing materials and certification package are approved for the actual natural gas operating conditions.
