Notes
1. Please read "Speed control circuit of hydraulic cylinder and notes" to assist with proper hydraulic circuit design.
If there is something wrong with the circuit design, it leads to the applications malfunction and damage. (Refer to page 17)
2. It is dangerous to air bleed during operation under high pressure. It must be done under lower pressure.
(For reference: the minimum operating range of the product within the circuit.)

Notes： 1. Minimum passage area when control side is fully opened is same as the maximum passage area in the table above.
2. It must be mounted with recommended torque. If mounting torque is insufficient,
the flow control valve may not be able to adjust the flow rate because of the metal seal structure.
3. Do not attach a used BZL to other clamps.
Flow control may not be done because the bottom depth difference of G thread makes metal sealing insufficient.
Notes： 1. Flow control circuit for double acting cylinder should have meter-out circuits for both the lock and release sides.
Meter-in control may have adverse effect by presence of air in the system.

Notes：
1. Since the area is sealing part, be careful not to damage it.
2. Since the area is the metal sealing part of BZL, be careful
not to damage it. (Especially when deburring)
3. No cutting chips or burr should be at the tolerance part of
machining hole.
4. As shown in the drawing, P1 port is used as the hydraulic supply
and P2 port as the clamp side.
5. If mounting plugs or fittings with G thread specification available
in the market, the dimension '※1' should be 12.5.
