LLA*A, Manifold Base for LVA Series Valve, Stacking Type
SMC high purity series LVA valve has three types of body materials (SUS/PPS/PFA) that can be selected based on the customers application. Special diaphragm construction insures gentle opening and closing that prevents the formation of micro-bubbles. A unique guide ring on the piston rod eliminates lateral motion of the poppet, greatly increasing seal life and reducing particle formation.
- Manifold base for high purity chemical valve
- Stacking type manifold
- Common IN/Individual OUT
- Port sizes: 1/4, 3/8, 1/2, 3/4
- Valve stations: 2 to 5
- Manifold material: PFA
