Question by: Roger M on Oct 23, 2025, 3:39 PM

got a hydraulic setup that can spike pretty high. what’s the pressure limit on this 1/2 inch needle valve?

Answer by: Customer Support on Oct 25, 2025, 11:24 AM

Pressure-wise, it’s rated for up to 10,000 PSI maximum operating pressure, with a minimum burst pressure listed at 20,000 PSI.

Question by: Ricky F on Jun 23, 2025, 7:16 AM

Running a natural gas line setup and need something that'll hold up past 5,000 PSI without sweating it. This valve rated high enough to handle that kind of pressure regular?

Answer by: Customer Support on Jun 24, 2025, 4:55 PM

Rated for up to 10,000 PSI with a minimum burst pressure of 20,000 PSI, so 5,000 PSI is well within its comfort zone for continuous use. The body and bonnet are zinc-plated AISI 1213 alloy steel, and the stem is hardened 316 stainless steel, so the construction backs up that pressure rating rather than just advertizing it on paper.
