LVA – Valves (All Types)

LVA-Z, High Purity Chemical Valve, Threaded Type

LVA-Z, High Purity Chemical Valve, Threaded 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.

  • High purity chemical valve, threaded type
  • Pilot port size: 1/8"
  • Fluid temperture: 0 to 100C
  • Body material: New PFA, PPS, Stainless Steel
