Normally I have seen needle valves. For some guages you need to dampen the gauge action - sort of like using a snubber before the guage - which is really just an orifice. So with a globe valve instead of a gate or globe you are able to open it partially and get some 'snubbing' action. With gauge isolation there is no flow, just a transmittal of pressure, so restrictions in the piping are OK and sometimes beneficial. In my experience working in many chemical plants, there are times when restricting the opening (needle valve) to a PG is useful to dampen and perhaps prevent a cycling reading due to pulsations, so a steady pressure can be read. Gate valves are often used as they are "multi-turn" and can not be bumped open by accident causing a hazard. Gates valve more often have all metal components so are less likely to leak or pass due to chemical attack of soft materials (non metals).
Common choice is a "gauge keeper" or valve block. This is often used between the main pipe isolation valve and the PG or other instrument. The Gauge keeper typically looks like a block of stainless with some T handles. It has built in single or doudle isolation valves (including needle) and a vent. It makes the job of changing a PG quick, safe, and easy.
