If you’re responsible for keeping a plant running, ball valves are rarely “just a valve”. You need isolation you can trust, a flow path that won’t strangle performance, and a format your team can maintain, automate, and replace without surprises.
The Kingdom KV-L Series is designed for exactly that reality: a flanged, full-port, 2-piece ball valve range for ASME Class 150 / 300 services, built around proven industry standards and practical maintenance features.
What’s in the KV-L range?
This product listing covers the four related models below:
- KV-L41 — Class 150, ISO 5211 direct mount, standard design
- KV-L42 — Class 300, ISO 5211 direct mount, standard design
- KV-L61 — Class 150, ISO 5211 direct mount, fire-safe design (fire-safe type)
- KV-L62 — Class 300, ISO 5211 direct mount, fire-safe design (fire-safe type)
In other words: pick pressure class first, then decide whether you need standard or fire-safe. (Fire safe is recommended and the most common type we sell.)
Core design features (what your team actually benefits from)
ISO 5211 direct mounting pad (built-in)
This is one of the biggest “time savers” in the real world: the valve is designed for direct actuator mounting without extra bracketry. That generally means faster installs, fewer alignment issues, and cleaner automation packages.
Full port (full bore) flow path
Full port valves reduce restriction through the valve, supporting flow efficiency and making life easier where pressure drop matters. It can also be helpful where pigging or cleaning routines benefit from a clear bore.
Fire-safe design available (KV-L61 / KV-L62)
Where site standards or risk assessments call for it, the fire-safe models are designed to meet fire-test expectations (see the standards section below). Fire-safe design is about maintaining a degree of shut-off integrity after exposure to fire conditions, using appropriate secondary sealing strategies.
Anti-static devices (ball–stem–body)
Anti-static design helps control static charge build-up during operation — a practical requirement in many hydrocarbon / hazardous area contexts.
Blow-out proof stem
A blow-out proof stem is a safety-minded design choice that helps prevent stem ejection under abnormal conditions, supporting safer maintenance and operation.
Pressure balance hole in ball slot
A pressure balance feature helps manage pressure effects around the ball/seat area, supporting consistent operation and helping reduce the chance of “sticky” operation in certain services.
Materials and seats to suit common industrial duties
The datasheet shows common body materials including WCB and CF8M, and common seat materials including PTFE / TFM1600 / TFM4215 (configuration dependent). This is why we quote the valve correctly for your media, temperature, and duty rather than guessing from a generic listing.
Standards (brief, plain-English guide)
The KV-L Series references widely used valve standards, which matters because it reduces ambiguity when you’re specifying replacements or documenting compliance:
- ASME B16.34 (Design): core pressure/temperature design rules for valves.
- ASME B16.10 (Face-to-Face): standardised end-to-end dimensions to aid replacement fit.
- ASME B16.5 (Flanges): flange dimensions/ratings for Class 150/300 pipework compatibility.
- API 598 (Inspection & testing): pressure test expectations for production valve testing.
- API 607 / ISO 10497 (Fire testing): fire-test standards (relevant to fire-safe models).
- ISO 5211 (Actuator mounting): direct mounting interface for automation packages.
- ISO 15848-1 / TA-Luft (Fugitive emissions): leakage control expectations (important for emissions-sensitive sites).
- NACE MR0175 / MR0103 (Optional): guidance for sour service/material suitability where required.

Quotation and supply
For now, this is a model-level listing (one product page for the range). We’ll confirm:
- Size (NPS), pressure class (150/300), body/trim materials
- Seat and packing selection for your duty (temperature/media)
- Manual lever, gear operator, or full automation package (actuator + accessories)
Request a quotation and we’ll come back with the best-fit configuration and lead time.
