Series/Model Information

Parker Rising Plug and Gauge/Root Valves are a screwed bonnet design and available with a variety of seat and seal materials. These valves feature bonnet lock plates for additional valve safety. The PV and PVG Series of valves provide a straight-through flow path in two orifice sizes. This "roddable" feature lets the user clean out the flow stream in dirty or a sticky application. Plus the seat is replaceable. These are tremendous advantages over a general needle style valve.
