How do you identify a hydraulic valve?

The Cross computer stock number is stamped in the shaded area on the handle end of the valve body on recent valves. On older valves, the Z casting number is on the back which would tell you which series, but individual functions would have to be described.

How does a spool valve work?

Spool valves regulate the flow of fluid in hydraulic systems. Spool valves would slide backward and forward so that the fluid flow can be either in one direction or another around a circuit of pipes. Spool valves have two basic components, a cylindrical barrel in which slides a plunger or spool.

What Does cir mean in hydraulics?

Usually expressed as CIR (cubic inches per revolution). For example, if a motor rated is at 2.2 CIR, this indicates that for every revolution, the motor displaces or expels 2.2 cubic inches of fluid.

How do I identify a valve?

The tags must identify the valve and usually do so by including the valve number. The tag also typically identifies the valve type and system of which the valve is a part. It’s important to note that the type of valve specified is dependent upon its function rather than on the design of the valve.

What are the different types of hydraulic valves?

We manufacture all types of hydraulic valves: from directional control valves to pressure control, flow control, shuttle, sequence, high pressure non-return and ball valves, from monoblock and sectional to manifold mounted, in-line and slip-in cartridge valves, from standard on/off valves to high-dynamic proportional valves.

What are sonnax valve body layouts?

Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. Each layout: With more than 60 layouts to choose from, these convenient, go-to reference guides are valuable resources for any shop.

How does a hydraulic pressure-reducing valve work?

At that point, the inlet of the valve will see system pressure, and the pressure-reducing valve in the “utility section” will regulate the pilot pressure to the hydraulic-remote controllers or the work section solenoids.

What is a 2 spool directional control valve with built-in relief?

A 2-spool directional control valve with built-in relief controls the lift and bucket cylinders of the loader. A return line filter is used to prevent contamination. The diagram shows a winch powered by a hydraulic motor. The directional control valve with built-in relief features optional flow control to control the speed of the winch .
