Description: The valve monoblock is available in 1 up to 6 spool models.The valve housing is casted in chrome alloy cast iron.As standard the valve has two built-in load check valves in the inlet section, one check for

Construction: The valves have parallel circuits, thereby allowing operation of more several combinations to meet customer's requirements.A direct operate main relief differential valve is standard on all valves. The spools are made from hardened steel and chrome plated to secure maximum protection against corrosion and wear. It is used with air-cylinders for lorrytruck cranes.

Mounting: The monoblock valve can upon request be delivered with built-in port relief valves and/or anti-cavitation check valves.
