Overview of directional seated valve type ROLV Directional seated valves are a type of directional valve. As cone valves they are tightly sealed, with zero leakage in the closed state. The directional seated valve type ROLV is available as a 3/2, 4/2 or 4/3-way directional seated valve with different plug types. The patented assembly consists of two parts: a round basic valve with the valve inserts, and an adapter plate which can be designed for manifold mounting with nominal size NG 6 as the standard connection pattern, or for direct pipe connection. Additional elements such as a check...

Manual override To actuate the valve: Use a steel pin or screwdriver etc. to depress the brass bolt (visible on the upper face). NOTICE The pressure at port T generates a load on the brass bolt acting on the area of # 3 mm; at 50 bar this is approx. 40 N! 1 Auxiliary tool for actuation (do not use any parts with sharp edges)
