Description
Flow is normally allowed from 3 to 2. When pilot pressure at 1 rises above the combined pressure of the spring bias, plus pressure at 3, the valve shifts to block flow. The valve may be used in switching or compensation type applications, and will maintain a constant pressure drop across a fixed (or variable) orifice upstream of 3 when installed and piloted per the diagram above.
¹) Only external seals for 10 valves
