4193A-10-100SS | Stainless Strainer, Check Valve, Backflow Protection

4193A-10-100SS | Stainless Strainer, Check Valve, Backflow Protection

The AR 4193A-10-100SS is a stainless steel in-line strainer with an integrated
check valve, engineered to protect pumps, valves, and downstream accessories by intercepting
debris and blocking reverse flow in high-pressure water circuits. Combining two essential
safeguards in one compact body reduces joint count, shortens installation time, and minimizes
potential leak paths, helping systems start clean and stay consistent through repeated cycles.
The strainer section traps particulates before they can score sealing faces or obstruct orifices,
while the check mechanism closes quickly when pressure falls or flow stops to discourage
siphoning, backwash, and contamination migrating upstream.

Design & Construction

• All-stainless housing resists corrosion in wet, detergent-rich environments and
  provides a rigid body that maintains dimensional stability under routine service.
• Smooth internal passages support steady flow and make it easier to flush captured
  material during maintenance.
• Robust external flats offer positive wrench engagement for secure installation
  and predictable disassembly.
• Integrated check valve and strainer in a single package reduce the number of
  fittings required and save space on compact carts and crowded skids.

Performance Advantages

• Improves prime retention and helps keep pumps from ingesting settled fines at restart, especially
  where lines are long, draws are intermittent, or equipment sits below fluid sources.
• Stabilizes performance by keeping nozzles, injectors, and regulators free of nuisance clogs,
  which translates into more consistent spray patterns and fewer unplanned interruptions.
• One-way flow path reduces the chance of backwash and reverse movement that can stir settled
  material into the inlet.

Installation & Use

• Position the unit with the flow arrow oriented correctly and ensure mating
  threads and sealing faces are clean.
• Start all connections by hand to avoid cross-threading, then snug evenly on the flats to a firm
  seat.
• Place the strainer ahead of sensitive components such as pumps, chemical
  injectors, unloaders, and fine-orifice accessories to provide a first line of defense against
  debris introduced during hose changes, tank fills, or job-site handling.
• When troubleshooting, use the combination body for two quick checks in one spot: confirm the
  screen is clear to restore flow, and verify check-valve function to rule out backflow as a cause
  of unexpected pressure changes.

Service & Maintenance

• At scheduled intervals or when flow begins to fall off, depressurize the system, isolate the
  line, and remove the strainer for inspection and cleaning.
• Rinse the screen and housing to clear trapped particles, verify that the check element moves
  freely and seats smoothly, then reassemble with clean threads and undamaged seals.
• Good housekeeping around fluid sources—keeping fill lids shut, using clean funnels or strainers
  when topping tanks, and capping hose ends during transport—helps prevent new debris from
  entering the line.

4193A-10-100SS Applications

• Wash bays and mobile rigs where clean, one-direction flow is critical.
• Plant maintenance stations and pre-treatment skids feeding precision accessories and manifolds.
• Rinse manifolds supplying fine-orifice tools used in industrial and commercial high-pressure
  water systems.

By merging filtration and backflow prevention in a compact stainless package, the
AR 4193A-10-100SS brings order and reliability to the inlet side of high-pressure
water systems. Operators see fewer clogged tips, less wear on seals and plungers, steadier
injector draw, and reduced downtime chasing debris-related faults—resulting in a more predictable
system that starts clean, shuts down clean, and delivers uniform spray from shift to shift.
