304 Stainless Steel Mini Ball Valve for Crypto Miner Water Cooling - 1/2 12mm

304 Stainless Steel Mini Ball Valve 1/2" 12mm | Isolation Valve for ASIC Miner Water Cooling

The 304 stainless steel mini ball valve is a compact 1/2" (12mm) full-port ball valve built from food-grade 304 stainless steel — the right isolation valve to put in line on an ASIC miner water cooling loop. The valve gives you a single-handle quarter-turn shutoff point for maintenance work: drop in the line between the radiator and the hashboard manifold, and you can isolate a miner for hashboard swap without draining the rest of the farm.

Rated for 1.6 to 6.4MPa working pressure and a -20°C to +180°C temperature range, the valve handles water, oil, and gas service comfortably. The 304 stainless construction means no corrosion in distilled or treated water service, no copper leaching into the coolant, and no degradation from the trace biocides used in mining hydro loops. The full-port ball offers minimal flow restriction when fully open.

Where the Mini Ball Valve Fits in a Mining Hydro Loop

• Per-miner isolation point — close to swap a hashboard without draining the entire farm loop.
• Radiator branch shutoff — isolate a radiator for cleaning or replacement.
• Drain port valve — drain the loop section by section during seasonal maintenance.
• Pump bypass shutoff — isolate the redundant pump in a dual-pump arrangement.
• Test rig isolation — bench tests on individual hashboards with quick-shutoff capability.

Construction and Materials

• 304 stainless steel body — corrosion-resistant, food-grade, no copper leaching.
• Full-port ball design — minimal flow restriction in the open position.
• 1/2" (12mm) port size — matches the standard 12-13mm tubing used in ASIC hydro loops.
• Quarter-turn handle — single-handed operation, clear open/closed position indication.
• PTFE seat seals — leak-tight closure with low operating torque.
• 1.6 to 6.4MPa working pressure — well above typical mining loop operating pressure (~0.3MPa).

304 Stainless Steel Mini Ball Valve Specifications

FAQ — 304 Stainless Steel Mini Ball Valve

Q: Will it fit standard 12mm hydro tubing?
A: The valve has G1/2" threaded ports that mate with standard pagoda (barb) fittings for 12-13mm OD tubing. Pair with a double-seal quick connector or threaded barb adapter for the tube-side connection.

Q: 304 vs 316 stainless — does it matter for mining loops?
A: For standard distilled-water or glycol-water mining coolant, 304 stainless is more than adequate. 316 is only worth the price premium in marine or chloride-heavy environments — not typical mining farm conditions.

Q: What torque does it take to operate?
A: With PTFE seats and the full-port design, expect 1-2 Nm operating torque at typical mining loop pressure. Easy single-handed quarter-turn.

Q: Pressure drop when fully open?
A: Negligible with the full-port design — the ball bore matches the port size, so flow restriction is essentially the same as straight pipe.

Q: Bulk pricing for farm rollouts?
A: Yes — email contact@lys-sz.com for volume pricing on multi-valve kits.
