Technical Feature
OPERATION:
Direct-acting, 3-way directional cartridges ( ① blocked, ② to ③ open) are switching
devices typically used in moderate flow circuits. They can be used by themselves or to
actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts
when the pressure differential between port ① and port ③ exceeds the setting.
Pressure at port ③ is directly additive to the setting of the valve. Because of this,
port ③ may not be useable as a work port in your circuit. -
