Product Overview
The PARKER 8V-P8K-SSV-PE is a precision instrumentation needle valve from Parker Hannifin’s 8V series, engineered for fine flow regulation and reliable isolation in analytical, process, and pneumatic control circuits. As a manually actuated needle valve, it uses a tapered needle stem that advances into a matching seat to deliver infinitely adjustable, repeatable throttling with minimal deadband. The “SSV” designation indicates a stainless steel body construction with a straight (in-line) flow path, while the “PE” suffix denotes a PTFE-based soft seat or packing configuration for enhanced sealing integrity. This valve is designed to serve as a dependable isolation and metering point on instrument impulse lines, sample systems, and low-volume pneumatic panels where leak-tight shutoff and precise flow control are essential.
