LVC23, High Purity Suck Back Valve, Single or Unit Type
High purity chemical valves, series LVC with integral fittings eliminate the possibility of residual liquid in pipe threads. In addition, the body has been designed for smooth flow with minimal internal dead space. Special diaphragm construction insures gentle opening and closing preventing the formation of micro-bubbles. A unique guide ring on the piston rod eliminates lateral motion of the poppet, increasing seal life and reducing particle formation. ***We are currently experiencing long lead times for fluoropolymer products. Please consult with SMC representative for accurate lead times***
- High purity suck back valve
- Body types: single; unit type with 2-way valve
- Withstand pressure: 1 MPa
- Operating pressure: 0 to 0.2 MPa
- Maximum suck back volume (cm 3 ): 0.1
