Specifications and configuration
Reference — FITOK BG three-piece ball valve series
| Parameter | Documented value / configuration |
|---|---|
| Valve construction | Three-piece full-bore ball valve with blowout-proof stem and floating ballConditions: scope: manufacturer series description; exact end and material variant must be selected |
| Manufacturer max working pressure | up to 69 barConditions: scope: maximum stated for standard materials; pressure-temperature curve and exact configuration control |
| Listed temperature range | -28 to 232 degCConditions: scope: standard material basis; not rated at 69 bar throughout the entire interval |
| Body material ordering choices | BGSS CF8M; BGS4 CF8Conditions: scope: body code only; wetted materials and coolant compatibility need full selected BOM |
| Documented end forms | NPT and BSP threads; tube fittings; pipe or tube socket/butt weld variantsConditions: scope: ordering options, not every combination available; confirm exact code |
| Standard seat material | PTFEConditions: scope: standard materials table; selected order code and fluid compatibility require confirmation |
| Manufacturer leak test statement | Each valve factory leak-tested with nitrogen or compressed air at rated pressureConditions: scope: manufacturer process; not proof of assembled liquid-loop acceptance criteria |
| Catalogued end connection examples | BG catalogue dimension table includes 1/8 in and 1/4 in female NPT/BSPP examples, plus pipe butt-weld ends; connection type and size belong to the selected ordering code, not every BG valve.Conditions: scope: Examples in BG dimension table, not the photographed valve's exact ends |

Overview
This metal BG-series three-piece ball valve is a candidate isolation component for a liquid-cooling branch where maintenance access and a large through-bore matter. It differs in construction and procurement inputs from the existing thermoplastic double-union valve.
Construction and interfaces
FITOK documents a full-bore, floating-ball design with a blowout-proof stem. The manufacturer product image shows a lever-operated split body and straight ports, but it does not identify one exact end-connection orifice or material order code.
Selection
Select the actual pressure-temperature rating from the applicable curve for the chosen body, seat and connection. The brochure's up-to 69 bar value and broad temperature statement are separate catalogue maxima, not a combined operating point or a liquid-cooling system guarantee.
Configuration options
The ordering guide lists CF8M and CF8 body code choices, PTFE standard seat material and NPT, BSP, tube-fitting and weld-end variants. Not every code combination is available; exact flow bore, orientation and cleaning package require a confirmed selection.
Application limits
The manufacturer reports factory leak tests with gas at rated pressure, which does not establish the acceptance test of a complete liquid assembly. Coolant chemistry, wetting materials, elastomers, galvanic pairing and the selected end standard must be checked before procurement.
