LP Series rising plug valves provide positive shut off for instrumentation, control and other systems, especially in system having particulate in system media, viscous fluids,and  corrosive and erosive media.  LPG Series Gauge valves have multiple ports to mount gauges, purge, bleed or other components. The valves feature a locked bonnet design for safety.  Non-wetted stem threads, non-rotating lower stems, and live-loaded chevron packing reduce maintenance and ensure a leak-tight stem seal.
