Ball Valve - Type 100/A/LD | IVR

IVR Type 100/A/LD Ball Valve

The IVR 100/A/LD is a 2-way brass ball valve intended for medium- and low-pressure gas distribution networks and hydrocarbon service. The valve body is specified as CW617N brass, with PTFE seats and a nominal pressure rating of PN 20.

Technical Data

• Valve type: 2-way full shut-off ball valve
• Body material: CW617N brass
• Seat material: PTFE
• Nominal pressure: PN 20
• Connection reference: ISO 331
• Standard reference: DIN
• Suitable media: fuel gas, low-/medium-pressure gas, compatible hydrocarbons

Typical Applications

• Fuel gas supply lines and branch isolation
• Auxiliary fuel networks for industrial equipment
• Industrial burner gas trains, where permitted by the applicable gas code
• Boiler rooms and plant utility gas systems
• Hydrocarbon isolation lines with media compatible with brass and PTFE

Operating Conditions and Selection Logic

Valve selection should verify the actual operating pressure, pressure transients, temperature range, gas classification, and compatibility of PTFE with the process medium. The PN 20 rating does not replace the need to check local gas regulations, installation standards, and manufacturer limits for temperature and service category.

For fuel gas service, the valve should be installed in an accessible location to allow manual operation, leakage checks, periodic inspection, and replacement if seat wear or stem leakage is detected.

Sealing and Maintenance Considerations

• PTFE seats provide the primary ball sealing interface.
• Suitability depends on temperature, hydrocarbon composition, and presence of condensates or additives.
• Periodic leak testing is recommended in gas service, especially after commissioning or maintenance work.
• Do not use the valve as a throttling device unless the manufacturer specifically permits that duty.

Actuation Options

The standard configuration is typically manual operation. If remote operation is required, actuator suitability must be checked against the valve stem design, torque requirement, cycle frequency, hazardous area classification, and fail-position requirement.

Variant Notes

The 100/A/LD designation should be compared with other IVR 100 series variants for connection type, handle arrangement, gas approval status, sealing materials, and allowable operating envelope. Procurement should be based on the exact datasheet and certification required for the installation.

FAQ

Can this valve be used for natural gas? It is intended for low- and medium-pressure gas networks, subject to confirmation of local gas approvals and installation code requirements.

Is it suitable for hydrocarbons? Yes, for compatible hydrocarbons, provided brass and PTFE are acceptable for the specific fluid and temperature.

What should be checked before installation? Pressure class, temperature, media compatibility, connection standard, gas certification, accessibility, and leakage test procedure.
