SD4M DIRECT OPERATED SEQUENCE VALVE

PLEASE ASK FOR PRICE!

The SD4M valve is a sequence valve with spool, in a stackable version. It is used to control two or more working lines in succession. It is a normally closed valve. It opens when the inlet pressure reaches the set value of the adjustment spring, allowing the fluid to pass through the pressure line. The valve remains open until the pressure in the circuit drops below the value set by adjustment of the spring. It is available with internal or external piloting, in three pressure regulation ranges up to 210 bar. It is supplied with a hexagon socket adjustment screw, locking nut and limitation of the maximum adjustment stroke.
