Ball Valve PN63/100 - Type 563/599 | JC

JC Type 563/599 PN63/100 Flanged Ball Valve

Two-way split-body full-bore ball valve with DIN flanged ends for high-pressure isolation service. Available in PN 63 and PN 100 pressure classes, with body materials in S.S. 316L, ASTM A105N or ASTM A352 LF2 and RPTFE seats.

Construction

• Full-bore flow path for low pressure drop and piggable or high-flow lines where applicable
• Split-body construction for inspection and maintenance access
• Blowout-proof stem
• Non-removable antistatic device
• Cavity pressure equalisation hole
• Live-loaded stem packing for reduced packing relaxation during thermal and pressure cycling
• DIN flanged end connections

Standards and Compliance

The valve range is specified with reference to PED, MSS SP 55, ATEX, Fire-Safe API 607 / ISO 10497 and fugitive-emission requirements ISO 15848 / TA-LUFT. Wetted materials are referenced against NACE MR0175 / ISO 15156 and NACE MR0103 / ISO 17945 where sour service or refinery service conditions apply.

Typical Applications

• Oil and gas production, processing and transfer lines
• Chemical and petrochemical units
• Power generation and utility systems
• Marine and offshore process lines
• Mining, pulp and paper, food and pharmaceutical utilities
• Isolation of special fluids where pressure class, material compatibility and leakage class are verified

Suitable Media and Operating Conditions

Typical media include hydrocarbons, process water, compatible chemicals, utility gases and selected aggressive fluids depending on body material, seat material and temperature. Final selection should consider design pressure and temperature, shut-off differential pressure, RPTFE compatibility, flange rating, fire-safe requirements and stem-emission limits.

Material Selection

• ASTM A105N: carbon steel option for general process duties, hydrocarbon service and non-corrosive fluids within the applicable temperature range.
• S.S. 316L: stainless steel option for corrosive or hygienic-compatible duties where austenitic stainless wetted parts are required.
• ASTM A352 LF2: low-temperature carbon steel option for services requiring impact-tested material properties.

PN 63 vs PN 100 Selection

PN 63 is normally selected where the pressure-temperature envelope and shut-off differential pressure remain within class limits. PN 100 is used when higher design pressure, transient pressure margin or isolation duty requires the higher pressure class. Selection must be checked against the full pressure-temperature rating of body, seats, seals and flanges.

Actuation and Sealing Options

The valve may be supplied for manual operation or prepared for pneumatic, electric or hydraulic actuation, subject to torque calculation at maximum differential pressure. Seat and seal selection should be based on media compatibility, operating temperature, cycling frequency, fire-safe requirements and fugitive-emission specification.

Engineering Checkpoints

• Confirm pressure-temperature rating for PN 63 or PN 100 duty
• Check RPTFE seat compatibility with the fluid and cleaning media
• Verify NACE requirements for sour or refinery service
• Define allowable stem leakage and packing inspection interval
• Confirm actuator torque with safety factor for end-of-life conditions

FAQ

Is this valve intended for throttling? No. It is primarily an isolation valve; continuous throttling can damage seats and ball surfaces.

When is LF2 preferred? LF2 is selected for low-temperature service where impact-tested carbon steel is required.

Can it be automated? Yes, provided actuator sizing is based on pressure differential, media condition, seat material and required operating time.
