    Parker's H Series needle valves are one of the most extensive in the process instrumentation industry and accommodates all types of instrumentation installations, specifications and applications. The Parker low and medium pressure needle valve has been purpose designed for operation with any fluid up to 20,000 psi (1379 bar) rating. The needle valve benefits from a fine threaded stem raiser, which gives increased stem sensitivity and accuracy and a non-rotating spindle tip which ensures for bubble tight shut off. The Parker needle valve also has the advantage of having no pressure retaining threads in contact with media as the operating threads outside wash-out area, this ensures the integrity of the system.
