APC by Schneider Electric ACAC10022 Isolation Valve Assemblies
The ACAC10022 from APC by Schneider Electric is a pair of isolation valve assemblies designed specifically for liquid cooling systems, featuring 1/2" ODF (outside diameter flared) connections. If you're commissioning or servicing a liquid-cooled rack or in-row cooling unit, isolation valves are the components that let you isolate a cooling loop segment without draining the entire system — a critical maintenance and serviceability feature in any production data center or high-density compute environment.

Overview
Liquid cooling deployments in data centers and high-density server rooms require reliable shutoff points at each cooling distribution unit, manifold branch, or rack-level connection. Without isolation valves, any maintenance activity on a single rack or cooling element requires a full system shutdown — an unacceptable constraint in environments running 24/7. The ACAC10022 addresses this directly: install these assemblies at the supply and return connections of a liquid cooling loop segment, and you can isolate, service, and reconnect individual cooling branches without taking the whole system offline. Explore the broader range of data center cooling accessories to complete your cooling infrastructure build-out.
Key Features
- 1/2" ODF Connection: The outside-diameter flared fitting standard is common in commercial refrigeration and precision cooling systems. This sizing matches the tubing used in most APC InRow and rear-door heat exchanger deployments, so you won't be hunting for adapters or dealing with conversion fittings that introduce leak points.
- Brass and Bronze Construction: Both materials are standard in fluid-handling applications for a reason — they resist corrosion in water-glycol cooling circuits and handle the pressure cycling that comes with thermal load changes. A zinc-heavy alloy or plastic body would be the wrong choice here; brass/bronze holds up across years of service without dezincification or stress cracking.
- Compact Form Factor (8.3" x 2.6" x 2.1"): At just over 8 inches wide and under 2.5 inches in each of the other dimensions, the ACAC10022 fits into the tight plumbing bays behind in-row cooling units and within cable management trays. Bulky valve assemblies in space-constrained server rooms create routing headaches; this profile avoids that.
- Lightweight at 1.39 lb: The sub-1.5 lb weight means these assemblies don't add meaningful stress to copper or flexible tubing runs. In overhead distribution or vertical manifold configurations, valve weight can pull on fittings over time — not a concern here.
- Isolation Without Full System Drain: The core operational benefit of any isolation valve assembly is the ability to section off a cooling loop. For facilities teams managing planned maintenance windows, this translates directly to reduced downtime scope — you isolate one branch, not the whole plant.
- Designed for Liquid Cooling System Integration: These assemblies are purpose-built for APC's liquid cooling ecosystem, which means connection geometry, pressure ratings, and flow path design are matched to the systems they serve rather than adapted from generic plumbing hardware.
Integration & Compatibility
The ACAC10022 is designed for use within APC by Schneider Electric liquid cooling infrastructure. The 1/2" ODF specification is the connection standard for a range of APC InRow cooling units and associated distribution piping. If you're working with a liquid cooling system that uses a different tubing OD or connection standard (e.g., 3/8" ODF or compression fittings), verify your system's plumbing spec before ordering — ODF fittings are not interchangeable across sizes. For facilities planning a new liquid cooling deployment, coordinate these valve assemblies alongside your data center infrastructure components to ensure consistent connection standards throughout the loop. The non-rack-mountable form factor means these are plumbing-path components, not panel-mounted devices — plan for tubing routing accordingly. If you're also specifying distribution manifolds or quick-connect couplings for your cooling loop, review cooling system accessories to identify compatible components from the same product family.
Frequently Asked Questions
Q: What does "1/2" ODF" mean and how do I verify it matches my cooling system?
A: ODF stands for Outside Diameter Flared — it refers to the outer diameter of the tubing that connects to this fitting. 1/2" ODF is a standard sizing in commercial and precision cooling systems. Check your existing cooling unit's connection spec or tubing OD before ordering. ODF fittings are not cross-compatible with compression or NPT fittings of the same nominal size.
Q: Is the ACAC10022 compatible with water-glycol cooling circuits?
A: The brass and bronze construction used in the ACAC10022 is the industry standard for water-glycol fluid-handling applications. Both metals are corrosion-resistant in glycol-water circuits and are widely specified in precision cooling infrastructure for this reason.
Q: Can the ACAC10022 be rack-mounted?
A: No. The ACAC10022 is not rack-mountable. It is a plumbing-path component intended for installation within the tubing runs of a liquid cooling system, not for panel or rack mounting.
Q: What are the exact dimensions and weight of the ACAC10022?
A: The ACAC10022 measures 8.3" x 2.6" x 2.1" (W x D x H) and weighs 1.39 lb.
Q: Is this a single valve or a pair?
A: The ACAC10022 is described as an isolation valve assembly — designed to isolate a cooling loop segment at both the supply and return connections. Verify quantity with the product listing before ordering if you need to cover multiple isolation points.
The ACAC10022 is the kind of component that doesn't get specified until someone learns the hard way why it should have been. The 1/2" ODF connection is what locks this into APC's precision cooling plumbing standard — if you're building out an InRow cooling deployment and you want the ability to service individual rack branches without a full coolant drain, this is the valve assembly to have in the BOM from day one.
Technical Highlights:
- Brass/Bronze Body: Not galvanized steel, not plastic — brass and bronze are the correct metals for glycol-water circuits. They handle the pressure cycling without degrading seals or corroding in the fluid path over a multi-year service life.
- 1/2" ODF Fitting Standard: ODF (outside-diameter flared) is what APC's liquid cooling tubing runs use — ordering a 3/8" or NPT equivalent by mistake means the assembly won't connect. Confirm your tubing OD before the order goes in.
- Compact 8.3" x 2.6" x 2.1" Profile: In-row cooling bays and under-floor distribution runs are tight. At 1.39 lb and just over 8 inches across, the ACAC10022 clears most routing constraints without requiring special brackets or offset adapters.
Deployment Considerations:
- These are plumbing-path components — plan your tubing routing before the cooling units are installed, not after. Retrofit valve installation in a live, pressurized cooling loop is a far more involved job than specifying them upfront.
- The non-rack-mountable designation means you need to account for valve body support in your plumbing design. Unsupported valve assemblies in vibration-prone environments can stress fittings over time — bracket or strap accordingly.
For a high-density compute environment running APC InRow cooling where the operational model requires per-rack maintenance without full-loop shutdowns, the ACAC10022 belongs in the design spec alongside the cooling units themselves — not as an afterthought.
