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.
