Port relief and anti-cavitation valve (AR) kit, non-adjustable, 1450 PSI. Includes plug, seal and fixed setting valve (794129307).

Description & Features

Designed for robust performance, this port relief and anti-cavitation valve (AR) kit offers a fixed setting of 1450 PSI, making it ideal for demanding industrial applications. Its cast-iron monoblock construction ensures durability while supporting up to five spools with interchangeable options. This valve kit includes a plug, seal, and fixed setting valve, enhancing its reliability in high-pressure environments.

With a maximum operating pressure of 5100 PSI on ports "P," "A," and "B," and a temperature range from -4°F to 185°F with NBR seals, this kit is built to withstand challenging conditions. The hardened steel, nickel-plated spools provide superior corrosion resistance, contributing to reduced internal leakage between 1.52 to 2.13 in³/min at 2285 PSI. The valve is compatible with fluid viscosities ranging from 10 to 400 cSt, optimized between 12 to 75 cSt for best performance.

Question by: Daryl J on Dec 4, 2025, 12:48 PM

What kind of fluid should I be running through this thing? I see a viscosity range listed.

Answer by: Customer Support on Dec 6, 2025, 6:24 AM

Optimal performance for this valve kit is with fluids in the 12 to 75 cSt range, though it can handle 10 to 400 cSt. Keep in mind that all the testing data was based on mineral oil at 16 cSt and a specific contamination level.
