Question by: Dale F on Jan 24, 2026, 10:07 AM
What's the highest temp this valve can handle? Gotta make sure it'll work for my application.
Answer by: Customer Support on Jan 26, 2026, 8:25 AM
This valve can operate in temperatures ranging from -100°F to 500°F. It should suit a wide range of hydraulic applications.
Question by: Dustin M on Nov 28, 2025, 12:32 PM
what's the pressure rating on this needle valve, and is it good for continuous high-pressure hydraulic lines?
Answer by: Customer Support on Nov 30, 2025, 8:02 AM
Rated up to 10,000 PSI operating pressure, with a minimum burst pressure of 20,000 PSI. That's a solid safety margin for demanding hydraulic work. The bar stock steel construction and hardened 316 stainless steel stem hold up well under sustained pressure, so running it continuously in a high-pressure line is well within what this valve is built for.
Question by: Neil A on Dec 20, 2025, 8:28 PM
got a 3/8 npt line here, is this valve actually 3/8 npt on the port?
Answer by: Customer Support on Dec 22, 2025, 4:01 PM
The port thread is 3/8 NPT, and the valve size is listed as 3/8.
