Instructions
Sub-plate
Sub-plates are available. Specify the sub-plate model number from the table above. When sub-plates are not used, the mounting surface should have
a good ma-chined finish.
If a remote control relief valve is used in the vent circuit, see page 3. In addition, if the internal volume of the vent
line is too large, chattering is likely to occur. Thus, as far as possible reduce the inside Dia. and the length of the pipe.
Pressure is limited by collars fitted. If a working pressure cannot be attained, remove some collars. One collar is
equivalent to 10 MPa (1450 PSI).
With a small flow, the setting pressure may be unstable. Use models numbered 03 and 06 with a flow rate above
8 L/min (2.1 U.S. GPM) and model 10 with 15 L/min (4.0 U.S. GPM).
There are two threaded connection pressure ports. They can be connected each other in-line; one as inlet and the
other as an outlet or the valve can be used by plugging one of the pressure ports.
