The 81068 FM Ball Valve is a precision-engineered flow control solution designed to seamlessly resolve thread mismatches in plumbing, HVAC, and light industrial systems. Its unique Female-Male (FM) connection (one internal-threaded port + one external-threaded port) and lever handle (L) enable rapid on/off control while bridging compatibility gaps between mixed-thread pipelines and fixtures.
| Model | Size | Connection Type | Operation |
|---|
| 1/2″FM-L | 1/2″ | Female (F) + Male (M) | Lever handle |
| 3/4″FM-L | 3/4″ | Female (F) + Male (M) | Lever handle |
| 1″FM-L | 1″ | Female (F) + Male (M) | Lever handle |
| 1-1/4″FM-L | 1-1/4″ | Female (F) + Male (M) | Lever handle |
| 1-1/2″FM-L | 1-1/2″ | Female (F) + Male (M) | Lever handle |
| 2″FM-L | 2″ | Female (F) + Male (M) | Lever handle |
- Material & Performance: Crafted from a corrosion-resistant alloy, it handles water, gas, and mild chemicals. Withstands up to 16 bar pressure and operates in temperatures ranging from -20°C to 120°C.
- Thread Compatibility Mastery: The FM design eliminates the need for adapters, directly connecting female-threaded pipes (via the male port) and male-threaded fittings (via the female port), streamlining installations in mixed-thread systems.
- Lever-Driven Efficiency: A 90° swing of the red lever switches flow from fully open to closed instantly, enabling swift emergency shutoffs or rapid system adjustments.
- Leak-Proof Precision: Precisely machined valve seats and threaded connections form an airtight seal, resisting pressure fluctuations (such as water hammer in plumbing) and preventing leakage.
- Full-Bore Design: The valve’s internal bore matches the pipe diameter, minimizing pressure loss and maximizing flow rate—critical for energy-efficient HVAC or high-demand industrial applications.
- Residential Plumbing: Bridges old female-threaded pipes to new male-threaded fixtures (e.g., a 1/2″FM-L connects a legacy female pipe to a modern male-threaded faucet).
- Commercial HVAC: Links male-threaded equipment (such as compressors) to female-threaded ducts (e.g., a 3/4″FM-L for mini-split systems).
- Light Industrial: Resolves thread mismatches in machinery pipelines (e.g., a 1″FM-L connects a male-threaded pump to a female-threaded process line).
- Adapter-Free Installation: The FM design reduces costs and installation time by eliminating the need for additional fittings in mixed-thread systems.
- Rapid Operation: The lever handle is three times faster than knob-style valves for on/off cycles, making it ideal for frequent use.
- Comprehensive Sizing: Covers diameters from 1/2″ to 2″, catering to residential, commercial, and industrial scale requirements.
- Low Maintenance: The corrosion-resistant alloy and robust sealing ensure a 10+ year service life with minimal upkeep.
