Chemical Valves

• High purity valve for chemical liquid, air operated
• Applicable fluid: Chemical liquid (acetone, isopropyl alcohol, sulfuric acid, deionized water...)
• High flow rates up to 113 l/min. Orifice diameter: 2 to 22 mm
• Port size: 1/8 to 1
• Body material: PFA, stainless steel or PPS
• Options: With flow rate adjustment, with indicator, with by-pass, high back pressure (0.5 MPa) tolerant, Low water hammer type, body wetted parts equivalent to EP grade.

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.

• High purity valve for chemical liquid, manually operated
• Applicable fluid: Chemical liquid (acetone, isopropyl alcohol, sulfuric acid, deionized water...)
• High flow rates up to 113 l/min. Orifice diameter: 4 to 22 mm
• Port size: 1/8 to 1
• Body material: PFA, stainless steel or PPS
• Option: body wetted parts equivalent to EP grade.

Series LVQ is a 2 port chemical valve with a non-metallic exterior. A high density PVDF housing offers increased chemical resistance and the special diaphragm construction insures gentle opening and closing preventing the formation of micro-bubbles. The LVQ guide ring eliminates lateral motion of the poppet, which reduces internal leakage.
