Design Features & Engineering Advantages
The male female threaded ball valve is purpose-built for reliability and ease of maintenance in professional installations:
Back Seal Multiple Leakage-Proof Design
redundant sealing architecture prevents external leakage at the stem, ensuring long service intervals and reduced maintenance cost.
Adjustable Packing Without Disassembly
field technicians can re-tighten or replace stem packing without removing the valve from the pipeline, minimizing downtime.
Seat Resilient Seal Design
spring-energized PTFE seat maintains positive sealing across wide temperature and pressure ranges, eliminating fugitive emissions.
Stem Anti-Ejection Design
the stem is mechanically constrained against ejection under pressure, meeting strict safety requirements for high-pressure and pressurized systems.
Full Bore Design
full port bore eliminates flow restriction, reducing pressure drop and enabling in-line cleaning with pigging equipment.
Butterfly-Type Handle (LTE)
the compact lever handle enables quarter-turn actuation with clear open/close indication; handle cover is PVC for operator protection.
Investment Casting Body
near-net-shape casting delivers consistent wall thickness and surface finish, minimizing porosity and improving structural integrity.
Multi-Thread Standard Compatibility
available with ASME, BSP, DIN, JIS, and ISO threads to accommodate global pipeline specifications.

Frequently Asked Questions
Q: What is the difference between a male female ball valve and a standard ball valve?
A: A male female ball valve (also called an MF ball valve or ball valve male x female) has asymmetric end connections - one end with external (male) threads and the other with internal (female) threads. This makes it ideal for connecting to pipes of opposite thread types without additional unions, reducing installation complexity and potential leak points. A standard ball valve typically has identical connections on both ends.
Q: What does 'butterfly type' mean in a ball valve?
A: In the context of this 2PC threaded ball valve, 'butterfly type' (LTE) refers to the flat, lever-style handle - resembling a butterfly wing - rather than a T-bar or elongated handle. This compact handle design is widely favored in tight-space installations and is a common configuration across European and Asian markets for male female threaded ball valves.
Q: What is the maximum working pressure of this male x female ball valve?
A: This valve is rated to 1,000 PSI (approximately 68.9 bar / 6.89 MPa) working pressure. For higher-pressure applications, please contact LEADTEK for availability of higher-rated versions.
Q: Which seat material should I select?
A: Select PTFE for standard water, oil, or gas service up to 120°C. Choose PTFE+20%CF (carbon-fiber reinforced PTFE) for higher-temperature service up to 200°C or where enhanced wear resistance is needed in abrasive or high-cycle applications.
Q: Is this female to male butterfly ball valve suitable for drinking water?
A: Yes. LEADTEK holds KC and KCW certifications confirming that our stainless steel ball valves meet Korean drinking-water sanitary safety standards. Products also comply with RoHS for restricted hazardous substances. For specific regulatory requirements in your market, please request the relevant test documentation.
