Question by: Dean C on Oct 12, 2025, 10:40 AM

Can this valve handle hydraulic systems that run pretty hot?

Answer by: Customer Support on Oct 14, 2025, 6:21 AM

This valve can operate in temperatures ranging from -15°F to 200°F, making it suitable for many hydraulic systems, but always confirm your system's peak temperature.

Question by: Brenda W on Sep 3, 2025, 2:38 PM

got a tight spot on the machine. how big is this valve body, roughly?

Answer by: Customer Support on Sep 5, 2025, 6:36 AM

Size-wise, the overall dimensions called out are about 3.75 inches long, 2.19 inches tall, and 1.38 inches across.

Question by: Keith S on Dec 10, 2025, 11:13 AM

Got a skid steer loader with a 3/4 NPT hydraulic line and we're running about 15 GPM through it. this valve gonna hold up to that?

Answer by: Customer Support on Dec 12, 2025, 6:52 AM

Running 15 GPM through this puts you well within its 20 GPM rated flow, so you've got plenty of headroom there. The 3/4-14 NPT female ports will thread right onto a standard 3/4 NPT male fitting without any adapter needed. It's built from carbon steel with a stainless steel needle and Viton O-rings, so it can handle the kind of continuous hydraulic duty a skid steer puts it through. Pressure rating is 5000 PSI for non-shock service, which covers most loader circuits comfortably.
