BVQ – Double Block and Bleed Valve, flange/flange – 9.6mm bore primary/secondary Ball Valves, Needle (vent) valve with plugged port.
The BVQ flange to flange double block bleed valves are suitable for modular gauge or instrument mounting and provide safe means of isolating and venting equipment via standard flange take off points.
Various flange ratings are available to suit different pressure ratings and sizes within the piping system.
Standard applications include static instrumentation, pressure gauges,manometers and pressure switches.
With its integral design, considerable cost, weight and space saving is gained over traditional installations, as well as increased safety due to reduced potential leak paths. With standard face to face dimensions retrofit and/or new
installations can be performed quickly and easily with minimal disruption to existing systems.
Manufactured with the primary and secondary isolate ball valves in line, the BVQ is fully rodable allowing for efficient cleaning and maintenance.
