This listing is for a brand new SN4, made in Taiwan, Youli brand high quality 80Lpm Sectional valve with two Joystick controls. We can supply this valve in 2 up to 12 functions, however, Joy sticks can only be mounted at end spools, as per photos. (they can clash) By default, any standard lever action is Spring Return to the Center cylinder spool.
Please email or call us for pricing to suit your application. Motor or Cylinder spools etc available
These valves are regularly used in hydraulic circuits to divert the flow of high-pressure oil and are typically used to control the speed and movement of hydraulic cylinders or motors.

This is a High-Quality Valve and has many outstanding features, including.
the built-in adjustable relief valve
high performance
high efficiency
small volume
mass flow
leak resistance
In addition to compact size, these control valves have fixed and large pull rods to control the direction
Please note
These 80 LPM valves require a separate "Power Beyond" sleeve to operate a valve downstream.
The detent is when you push/pull a lever, it stays forward/back at that position until you move it back to the center.
Installation
As per photos, there is a choice of two pressure ports "P" (only use one), two "T" Tank return ports and also there is a "C" port. This "C" port is for the: Power Beyond function. This allows another valve to run pressure from this C port downstream if necessary. (must be a lower volume though). A & B ports run to your cylinder or other functions.

Technicians Advice

Sectional valves like the SN4 earn their keep when your function count grows – unlike a monoblock, you can add or swap a section later instead of replacing the whole valve. Keep joysticks on the end spools only (the linkages clash mid-bank), and if you are running two functions at once regularly, ask us about the power beyond plug so a downstream valve gets full flow. Call us with your machine details and we will spec the sections, spools and relief with the factory.
