Question by: Cody L on Aug 4, 2025, 4:43 PM

What's the temperature range on this thing? Got equipment running in some pretty brutal conditions and need to know if it'll hold up.

Answer by: Customer Support on Aug 6, 2025, 7:09 AM

Ambient temps between -40°F and 140°F are within spec for this spool. On the fluid side, you're looking at -4°F to 176°F using the standard Buna-N seals. So unless you're dealing with something truly extreme on either end, it should handle most field conditions without issue.

Question by: Joyce J on Aug 11, 2025, 2:37 PM

Can this valve handle a good bit of pressure? I'm running some heavy equipment.

Answer by: Customer Support on Aug 12, 2025, 8:27 PM

It’s rated for up to 4600 PSI in parallel circuits, but only 3050 PSI in series circuits. Make sure your system is within those limits.
