Product Overview
What Is a Lockable Handle Flanged Ball Valve?
For procurement engineers specifying to a JIS B project standard, this valve answers three common RFQ checkpoints in a single line item: flanged end connections to JIS B 2220 Type 10K, lockable handle for LOTO isolation compliance, and fire-safe / anti-static construction for hazardous area classification. The 2-piece investment-cast body (CF8 or CF8M) is dimensionally verified to JIS B 2002 face-to-face and inspected per JIS B 2003 - with full material traceability available on request.
For OEM equipment builders, the full-bore flanged design provides a Cv-neutral isolation point that integrates directly into JIS-standard skid pipework without reducers or adapters.
| Single-source procurement - flanged ends eliminate separate flange fittings | LOTO-ready - lockable handle supports energy isolation compliance without additional hardware |
| Fire-safe design - suitable for specification in oil & gas and petrochemical project BOMs | Anti-static design - standard on all units, meeting EX-zone installation requirements |

Design Features

Lockable Lever Handle - LOTO Compliant
The cast stainless steel lever incorporates a through-hole lock tab, accepting a standard padlock (not included) to secure the valve in the open or closed position. Eliminates the need for separate lockout devices on the handle - directly supports LOTO (Lockout/Tagout) energy isolation procedures required in most industrial safety management systems.

Fire-Safe Design
Body and bonnet geometry maintain pressure containment integrity at elevated temperatures in fire conditions - a mandatory specification requirement for many oil & gas, petrochemical, and LNG project BOMs. Verified per standard fire test protocols.

Anti-Static Electricity Design (Standard)
Conductive path between ball, stem, and body is maintained as standard - dissipating static charge buildup from flowing media. Required for flammable fluid and gas service in classified hazardous areas. Anti-static option noted; confirm with your project specification.

Back Seat & Multiple Leakage-Proof Design
A secondary containment seal behind the primary stem packing provides an additional barrier against fugitive emissions - allowing stem packing to be inspected or adjusted under operating pressure. For maintenance planners managing large valve populations, this eliminates the need to schedule a full valve removal for routine packing checks.

In-Service Packing Adjustment
Stem packing compression can be increased in-service without breaking the flange connection or removing the valve from line. In high-cycle or thermally stressed applications where packing wear is accelerated, this feature directly reduces the maintenance labor cost per valve per year.

Full Bore Design
The through-bore diameter matches the nominal pipe size - preserving system Cv value and eliminating the localized velocity increase that causes erosion at reduced-bore seats. For process engineers balancing pressure budget across a pipeline, a full-bore flanged isolation valve contributes zero pressure drop to the system model.

Seat Resilient Seal & Stem Anti-Ejection Design
pring-energized PTFE seats ensure consistent bubble-tight shutoff across thermal cycling and pressure fluctuation. The anti-ejection stem retainer prevents stem blowout under full rated pressure - a non-negotiable safety feature for pressurized service.

Investment Casting Body
Lost-wax investment casting controls grain structure at the casting stage - producing a denser, more uniform stainless steel body than sand casting, with tighter as-cast dimensional tolerances. For incoming inspection teams, this means fewer non-conformances on critical dimensions such as flange face flatness and bolt circle position.

Industry Applications

Oil & Gas - Upstream, Midstream & Refining
Project specifications for hydrocarbon service require flanged ends, fire-safe construction, anti-static design, and lockable isolation handles at LOTO points - this valve meets all four as standard, with no line-item deviations. CF8M (SS316) body and F316 internals cover H₂S and corrosive hydrocarbon environments without a material upgrade order.

Petrochemical & Chemical Process
Full-bore flow path, PTFE+20%CF seats rated to 240°C, and built-in anti-static design address the three most common specification checkpoints for isolation valves on aggressive media lines - in a single standard configuration. For procurement teams consolidating valve vendors across a project, this eliminates the need for a separate high-temperature valve variant on most process lines.

LNG & Gas Distribution Infrastructure
Fire-safe body construction, lockable isolation handle, and full-bore flow path cover the standard specification requirements for manually operated valves in LNG terminal and gas distribution pipework. For service below -40°C, consult our engineering team to confirm seat material compatibility before specifying.

Frequently Asked Questions
Q: What does "JIS Type 10K" mean on a flanged ball valve?
A: JIS (Japanese Industrial Standards) Type 10K refers to the pressure class and flange drilling pattern defined under JIS B 2220. "10K" indicates a nominal pressure rating of 10 kgf/cm² (approximately 1 MPa / 145 PSI) at the reference temperature. It is the most widely used JIS flange class in industrial pipework across Japan, South Korea, and JIS-standard projects in Southeast Asia.
Q: What is the design standard for this flanged ball valve with lockable handle?
A: The valve is designed to ASME B16.34, with face-to-face dimensions per JIS B 2002, flange dimensions per JIS B 2220, and inspection per JIS B 2003.
Q: Is the lockable handle standard, or is it an optional upgrade?
A: The lockable lever handle is a standard feature on this model - not a paid upgrade or field modification. Every unit ships with the lockable handle as designed.
Q: What is the temperature rating for this JIS flanged ball valve?
A: With M111 seat and seal materials: -40°C to 200°C. With M111+20%CF (carbon fiber reinforced) upgrade: -40°C to 240°C. Please specify your operating temperature when submitting your RFQ so we can confirm the correct seat package.
Q: Is fire-safe design standard on this valve?
A: Yes. Fire-safe design is a standard feature of this model, not an optional specification. This makes it suitable for inclusion in oil & gas, petrochemical, and LNG project bills of materials where fire-safe valve certification is required.
Q: Is anti-static design included as standard?
A: Yes. Anti-static protection is standard on all units, providing a conductive path between ball, stem, and body to dissipate static charge from flowing media - required for flammable fluid service and hazardous area installations.
Q: What sizes are available?
A: Standard range is ½" to 4" (DN15 to DN100) in JIS Type 10K. Contact LEADTEK for availability of larger sizes or alternative pressure classes.
Q: Can LEADTEK supply with OEM markings or a private label?
A: Yes. Laser engraving of customer logo, part number, pressure class, and material grade is available directly on the valve body. For distributors building a private-label product range, we can also customize the handle finish and produce branded outer packaging. Include your marking specification in the RFQ and we will confirm feasibility and any tooling cost at quotation stage.
Q: What QC documentation is provided with each shipment?
A: Every shipment includes a pressure test certificate per JIS B 2003. For project orders requiring full material traceability, we provide mill test reports (MTRs) linked to the heat number of each casting batch. Third-party inspection by SGS, Bureau Veritas, or TÜV can be arranged at buyer's request and cost. ISO 9001 certificate and RoHS declaration are available as standard supporting documents.
Q: What is the MOQ for bulk orders?
A: Standard MOQ is 100 pcs per size and specification combination for JIS Type 10K configurations. For project orders specifying multiple sizes across a single BOM, mixed-size orders are accepted with the same per-size minimum. If you are evaluating this valve for a new product line or project specification, free samples are available for qualified buyers - contact our export team with your company and application details.
