Parker Needle Valves
Needle Valve,Screwed Bonnet 6000 PSI - NP6 Series

Parker's NP6 needle valves are designed with packing below the stem threads and a two-piece stem for critical applications up to 6,000 PSI (414 BAR).

Parker's NP6 Needle Valves are severe service, needle valves. They are designed with the packing below the stem threads and a two-piece stem for critical systems up to 6,000 PSI (414 BAR). The packing below the threads protects the flow stream from thread lubricant contamination or washout and also protects the stem threads from potential damaging effects of the media. The two-piece stem produces a non-rotating lower stem for superior, repeatable sealing and reduced packing wear.
