⚙️In-depth Working Principle

Diaphragm closed-loop feedback: Rotate and pull the adjustment knob to compress the setting spring. The spring pushes the diaphragm downwards and opens the poppet valve to raise output pressure.
Feedback chamber: Downstream output pressure is introduced to the lower diaphragm chamber, generating upward counter-force against spring force. When output pressure reaches setpoint, the poppet throttles automatically to maintain stable regulated pressure.
Relieving function (شفرة 0): When outlet pressure exceeds set value, the diaphragm lifts upward and opens the relief vent. Excess compressed air is exhausted directly to atmosphere for downstream equipment protection.

ملحوظة: Non-relieving version (code1) cannot release downstream overpressure, only for closed-load circuits. MC202-R00 is relieving-type, selected for most pneumatic applications.

🔄Compatible Replacement Options

OEM Model	Direct Replacement Remarks
MC202‑R00TF	Identical body, port changed to NPT1/2. Thread incompatible, adaptor required
MC238‑R00	Same specification, G3/8 port. Port mismatch, cannot drop‑in replace
Domestic alternative reference	AIRTAC GR600‑15; SMC AR60‑10; Check flow curve deviation, relieving‑type regulator is mandatory

⚠️Selection Pitfalls & Hard Constraints

Forbidden media: Water, hydraulic oil, الغاز المسببة للتآكل; Only for dry compressed air.
Temperature boundary: Do NOT use below-5℃; Ice formation will permanently damage diaphragm. Condensation accelerates seal ageing.
Mounting requirement: Vertical installation preferred for valve body; Use OEM lock-nut for panel mounting. Never tighten the unit by twisting adjustment knob.
Maintenance note: NBR diaphragm service life shortened by heavily oil-laden compressed air; Visual inspection every 6-12 months recommended.
Flow limitation: Refer to MC-series flow characteristic curves for high-flow conditions; Excessive pressure drop indicates undersized selection.
Modular assembly: Only mate with MC-series components; Do NOT mix-assemble with legacy C-series air-prep units.

🛠️Typical Troubleshooting

أعراض	السبب الجذري	Resolution Procedure
Cannot build‑up outlet pressure	Insufficient inlet pressure; Poppet contaminated; Damaged setting spring	Check supply pressure; Disassemble & clean poppet; Replace spring assembly
Residual outlet pressure even when adjusted to zero	Poppet seat wear / foreign particle jamming	Clean internal parts; Replace regulator body if severe wear occurs
Continuous relief venting	Downstream leakage; Internal diaphragm rupture	Eliminate downstream air leakage first; If still venting, replace regulator
Adjustment knob fails to lock	Worn internal locking mechanism	Replace knob sub‑assembly

🏭Typical Application Scenarios

Automotive welding lines, آلات التعبئة والتغليف, machine-tool pneumatic circuits, automation shop-floor air distribution. Frequently combined with MC filter MC202-F00 and MC lubricator MC202-L00 to build FR / FRL air-prep units.

Camozzi MC202-R00 Complete Material List (OEM datasheet)

عنصر	Material Description	ملاحظات
Main valve body housing	Die‑cast zinc alloy	Industrial grey painted surface finish
Adjustment knob & upper cap	Engineering polymer (PA Nylon)	Grey lockable handwheel assembly
Diaphragm & all O‑ring seals	نبر (Nitrile Butadiene Rubber)	For compressed air; Operating range‑5~+50℃, not resistant to strong solvents / aromatic oils
Setting spring & return spring	Stainless steel	Anti‑corrosion property
Poppet assembly	Steel + NBR sealing sub‑assembly	Realizes inlet‑relief closed‑loop control

ملحوظة: MC202-R00 is regulator only without filter bowl. The matching filter MC202-F00 is equipped with metal bowl; No bowl structure on regulator unit.

Material-related Boundary Notes

Seal service life: NBR seals age rapidly under synthetic oil / chemical solvent exposure; Perform inspection every 6-12 شهور.
Housing limitation: Zinc-alloy housing is NOT suitable for heavy corrosive environment (acid gas, رذاذ الملح). Select stainless-steel series for corrosive service.
Temperature constraint: Material operating window-5℃~+50℃. Condensation and icing will cause permanent NBR diaphragm failure.

📌Panel Through-mounting

غرض	المعلمة
Panel mounting lock‑nut thread	M47×1.5	Bulkhead thread on upper body
Panel cut‑out diameter	Φ46 mm	Round hole only, do NOT tap thread
Max allowable panel thickness	9 mm	Limited by nut travel
Max knob outer diameter	62 mm	Knob protrudes out of panel; maintain ≥5 mm clearance around knob

Mounting instruction: Insert body from rear of panel, fasten with OEM M47×1.5 lock-nut. Never tighten the unit by twisting adjustment knob, locking-mechanism damage will occur.

📌Wall-bracket Mounting (Optional MC2-ST bracket, order separately)

Bracket mounting hole center distance:52 mm; Hole diameter Φ5.5 mm, secured with M5 screws.

Vertical mounting preferred; horizontal installation permitted; upside-down installation forbidden.

📌Modular Assembly (MC-series combination)

Module mating face width:60 mm; Assemble via tie-rods or MC202-FL flange. Do NOT mix-assemble with legacy C-series air-prep units.

⚠️Mounting Pitfalls

Strictly adopt Φ46 cut-out. Oversized hole causes mis-positioning; undersized hole prevents assembly. Never hammer the body into place.
M47×1.5 is fine-thread bulk-head nut; standard off-the-shelf M47 nut is non-interchangeable. Source spare nut from Camozzi.
Knob must be freely pullable-up / push-down after panel mounting; panel shall not jam knob movement.

اختيار المفتاح & Installation Warnings
Port mismatch: SMC AR60-10 is 1-inch port, cannot directly mate with 1/2-inch piping of the other two regulators. Thread adaptor will introduce extra pressure drop.
Non-reusable cut-out: Three models require distinct panel hole sizes. Re-verify cut-out dimension upon model change.
Installation prohibition: Upside-down mounting forbidden for all three regulators. Use OEM lock-nut for panel mounting; never tighten via adjustment knob.
Modular assembly: Only assemble with units of the same product series. Cross-series assembly between Camozzi MC, SMC AR and AIRTAC GR is prohibited.
