Description
Applications for needle valves:
Intended to isolate the pressure gauge from the measured fluid or to provide a means of throttling or dampening pressure pulsation.
Special features of needle valves:
Pressure Rating
Hard seat models 10,000 psi
Soft seat models 6,000 psi
Operating Temperature
Media: max. 200°F (+93°C)
min. 0°F (-18°C)
Flow Rate
Hard seat models Max. Cv.52
Soft seat models Max. Cv.83
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.
