- Lignes directrices de sélection & Solutions de remplacement
Lignes directrices de sélection
- Port Matching
Confirm system port is G3/8 BSPP to avoid thread mismatch.
- Pressure Compatibility
Inlet pressure shall not exceed 16 bar; outlet requirement within 0.5–10 bar.
For higher outlet pressure (10–16 bar), select MC Series high-pressure version.
- Flow Requirement
Select proper size according to system air consumption; MC238 suits medium flow systems.
- Méthode d'installation
Reserve sufficient mounting space; observe left-to-right flow direction for in-line installation.
- Optional Functions
Pressure gauge required: Choose MC238-R01
Bypass valve required: Choose MC238-R02 and other bypass versions
