⚙️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 (código 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.
Observação: 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, Porta G3/8. 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, gás corrosivo; 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.
- Montagem modular: Only mate with MC-series components; Do NOT mix-assemble with legacy C-series air-prep units.
🛠️Typical Troubleshooting
| Sintoma | Causa raiz | Resolution Procedure |
| Cannot build‑up outlet pressure | Pressão de entrada insuficiente; 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, máquinas de embalagem, 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)
| Componente | Material Description | Observações |
| 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 | NBR (Nitrile Butadiene Rubber) | Para ar comprimido; Operating range‑5~+50℃, not resistant to strong solvents / aromatic oils |
| Setting spring & return spring | Aço inoxidável | Anti‑corrosion property |
| Poppet assembly | Aço + NBR sealing sub‑assembly | Realizes inlet‑relief closed‑loop control |
Observação: 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 meses.
- Housing limitation: Zinc-alloy housing is NOT suitable for heavy corrosive environment (acid gas, salt spray). 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
| Item | Parâmetro | |
| 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 milímetros | Limited by nut travel |
| Max knob outer diameter | 62 milímetros | 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 milímetros; 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 milímetros; 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.

- Seleção de chave & 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.
- Montagem modular: Only assemble with units of the same product series. Cross-series assembly between Camozzi MC, SMC AR and AIRTAC GR is prohibited.
