VALVE DUAL

VALVE DUAL 3716 8020 00 is usually found in the hydraulic circuit, handling two separate pressure lines. It’s often used for things like controlling the feed cylinder, pushing oil one way to extend and the other to retract, or maybe for a specific auxiliary function that needs a push-pull action. Think of it as a gatekeeper for two distinct hydraulic movements, making sure the right amount of oil goes where it needs to, when it needs to, keeping your rig's functions operating smoothly and predictably.

When this valve starts going bad, you'll definitely notice it. Usually, what happens is the internal seals wear out, or the spool gets sticky. You might see the feed cylinder start to drift when it's supposed to be holding position, or maybe it gets sluggish on one direction, taking longer to respond than it should. Sometimes, you'll hear a subtle chattering or a different hydraulic noise as the oil tries to bypass a worn seal. Pressure gauges might show some fluctuation too, especially when you're trying to activate the function it controls. It's not always a sudden failure; sometimes it's a slow creep of performance loss that gets worse over time.

When you're swapping one of these out, make sure you clean the area thoroughly before you even crack the lines. You don't want any crud getting into the new valve or the system. Also, always check the condition of the hydraulic lines and fittings going to and from the valve. Sometimes a restricted line or a loose fitting can mimic a valve issue. And don't forget to properly bleed the system after replacement; trapped air can cause all sorts of weird behavior and make you think the new valve is bad when it's perfectly fine.
