Ball Valve - Type 685 | IVR

IVR Type 685 Ball Valve

The IVR 685 is an AISI 316L stainless steel ball valve, PN 16, with DIN flanged connections and an ISO 5211 mounting interface for actuator installation. It is used for on/off isolation in industrial piping systems where stainless steel wetted parts are required.

Construction

• Body material: AISI 316L stainless steel
• Connection: flanged or wafer-type flanged configuration
• Flange standard: DIN
• Pressure rating: PN 16
• Seat material: PTFE reinforced with glass fiber
• Actuator interface: ISO 5211 mounting flange
• Manufacturer description: AISI 316 stainless steel ball valve, ISO 5211 flange, flanged ends PN16

Typical Applications

• Process water and utility water circuits
• Compressed air distribution and isolation points
• Auxiliary industrial services
• Chemical fluids compatible with AISI 316L and PTFE
• Automated on/off duties in process and HVAC-related industrial systems

Suitable Media and Operating Conditions

The valve should be selected for clean or moderately clean fluids where a quarter-turn shut-off valve is acceptable. Media compatibility must be checked against AISI 316L body material and PTFE glass-filled seats. Operating temperature is governed by the seat, seals, pressure rating, and fluid characteristics; the applicable manufacturer pressure-temperature chart should be used for final selection.

Variant Selection

• Flanged version: suited for conventional DIN flanged pipework where standard face-to-face length is available.
• Wafer-type flanged version: reduces installed length between flanges, but requires accurate pipe alignment, correct gasket selection, and controlled bolt tightening.

Automation and Process Control

The ISO 5211 interface allows direct mounting of pneumatic or electric actuators for remote on/off control. Actuator sizing should consider breakaway torque, differential pressure, cycling frequency, fluid viscosity, temperature, and any tendency of the medium to crystallize, polymerize, or deposit solids during shutdown.

Maintenance and Leakage Considerations

Before installation, verify flange alignment, gasket compatibility, bolt pattern, and pipe support. For automated service, periodic cycling may be required where the medium can cause sticking. Seat leakage class and stem sealing performance should be confirmed against the project specification and operating medium.

FAQ

Can the IVR 685 be automated?
Yes. The ISO 5211 mounting pad permits pneumatic or electric actuator installation, subject to torque verification.

Is it suitable for chemicals?
Only where the chemical is compatible with AISI 316L and PTFE glass-filled seats at the specified pressure and temperature.

What is the main selection limit?
The key limits are PN 16 pressure class, seat temperature capability, media compatibility, and available installation length.
