Feb 21, 2018. #1. Anyone have an ec35 mini-x or manual on one? I am trying to identify where . On most excavator circuits, there are several relief valves, typically main relief valve and circuit relief valves. The primary purpose of the main relief valve is to protect the pump/pumps from excessive pressure on the supply circuit that would damage them.Pressure-relief valves, which are safety valves that stop pressure building up in the hydraulic system and prevent overpressure. Flow-control valves that control the flow rate of hydraulic fluid to cylinders and motors, regulating the speed of those components.
Hydraulic Pressure Relief Valve to avoid hydraulic system overload. Previous part number was 6686360. Fits the following Bobcat equipment: All-Wheel Loaders: A220, A300, A770. Attachments: Angle Broom, Clamp, Grader. Articulated .
I have an older Bobcat 331 Mini excavator. The hydraulic pressure to the whole system is low. The service manual says to adjust the main relief valves as needed. Relief Valve Number One (Right Hand Travel, Boom Offset and Boom Valve Sections) should be set at 2650lbs and I can adjust it up to 2650 by adjusting its main relief valve.Pilot Control Manifold for a Mini-Excavator Grapple. This simple circuit provides pilot control of hydraulic pressure for a 1 to 2.6 ton excavator. It uses two solenoid valves, a pressure relief valve and four check valves. Weather-Resistant Control of Electro-Hydraulic FunctionsKit to install an electric-operated valve and a switch in your cab to divert the flow from an unused hydraulic circuit (i.e. extendahoe or backhoe stabilizers). An owner/operator can install. Only for carriers under 20,000 lbs. I am getting a thumb for my machine and need to set the auxiliary relief to 2200 psi. Is it as simple as installing a gauge on the excavator auxiliary hydraulics (at the quick coupler) and operating the auxiliary valve and adjusting pressure accordingly for each side?
Relief pressure appears to be higher at WOT due to the much larger flow of fluid through the restrictive orifice of the relief valve. Do the pressure checks at engine idle or up to 1/4 throttle. Relief pressure can be attained only when a cylinder reaches end of stroke in either direction and is held there for a couple of seconds. You have the relief valve in the right place and you don't need a second one, unless you're using another attachment that may indeed need a another relief valve. From your description, looks like it's also doing its job just fine.
Feb 21, 2018. #1. Anyone have an ec35 mini-x or manual on one? I am trying to identify where the relief valves are to clean them out. Had rotary transfer seals disintegrate and go through the system. After replacement certain controls are weak and apparently not operating at pressure.
