Specifications for needle valves:

Needle valves work to extend the life of the pressure gauge by helping throttle or dampen pressure pulsations. Pulsation is one of the most  common causes of gauge failure.

Applying accessories, such as needle valves, helps ensure accurate readings from local indicators. Hard seat needle values can withstand pressures up to 10,000 psi.
