The Kingdom EN PN10–PN40 Direct Mount range is built for exactly that. It’s a full-port, 2-piece, flanged ball valve series covering PN10, PN16, PN25, and PN40, with a built-in ISO 5211 direct mounting pad for clean actuator installation (or simple future upgrades from manual to actuated).

Model options (quick selector)

Choose standard or fire-safe, then select the PN rating code:

• Standard type (KV-L4*): KV-L4J (PN10) / KV-L4K (PN16) / KV-L4M (PN25) / KV-L4N (PN40)
• Fire-safe type (KV-L6*): KV-L6J (PN10) / KV-L6K (PN16) / KV-L6M (PN25) / KV-L6N (PN40)

(Code guide: J=PN10, K=PN16, M=PN25, N=PN40.)

Why teams choose direct-mount ball valves

If you’ve ever lost time fighting actuator alignment, couplers, or “it fits but it binds,” you already know the value of a clean mounting interface. Kingdom specifies a built-in ISO 5211 mounting pad, which is designed to reduce extra mounting hardware and make automation packages more straightforward. For maintenance managers, that typically means: cleaner shutdown workpacks (fewer bits and pieces), quicker actuator swaps, less risk of misalignment-driven torque and sticking issues.

Key features (translated into real-world value)

Full port (full bore) helps avoid turning a line into its own restriction. It’s the simplest way to reduce the risk of post-change complaints about flow and pressure drop.

Anti-static device (ball–stem–body) supports electrical continuity — a common requirement in certain hazardous-area or hydrocarbon duties.

Blow-out proof stem is a safety-minded design detail that helps reduce severity in abnormal pressure scenarios and supports safer maintenance culture.

Pressure balance hole in the ball slot is listed to help manage pressure effects at the ball/seat interface, which can support smoother operation and reduce “stiff valve” callouts in some services.

TA-Luft / ISO 15848-1 design approval is relevant for sites focused on leak reduction and fugitive emissions expectations — fewer persistent weeps means fewer repeat work orders.

NACE MR0175 / MR0103 optional is there for when your service conditions demand it (e.g., sour duties). It provides a route to specify materials correctly rather than “best guessing” and paying for it later.

Fire-safe option (KV-L6*)

Where your site standards call for fire-safe isolation, the KV-L6* models are specified as Fire Safe design approved, with fire test references API 607 (5th edition) and ISO 10497.

That’s useful when you need the spec to stand up to engineering review, insurer expectations, or safety-case documentation — without switching to a completely different valve family.

Standards (plain-English “what this means”)

Kingdom references common EN standards to reduce uncertainty when replacing or documenting valves:

• EN 1092-1 (Flanges) — matches EN flange drilling/dimensions across PN10–PN40.
• EN 558 (Face-to-face) — standard end-to-end lengths to help replacements fit without pipework modifications.
• EN 12516-1 (Design) — design rules for pressure/temperature integrity.
• EN 12266-1 (Testing) — inspection and pressure testing expectations.
• ISO 5211 (Mounting) — the actuator mounting interface used for direct-mount automation.

Operation & quotation (so we can price it quickly)

Kingdom lists operation by size: lever DN15–DN65, gear option DN65–DN200, and pipe handle DN80–DN200.

To quote accurately, send:
DN size + PN rating (10/16/25/40) + standard or fire-safe + body material + seat selection + media + temperature + manual/actuated (and any limit switch/positioner needs).

Send your enquiry and we’ll confirm the correct model code and a suitable configuration for your service.

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.
