Contact SMC if a stopper cylinder is to be used for stopping a load that is connected directly to a cylinder, as this will cause the cylinder's thrust to act as a horizontal load.
This product cannot be used as a check regulator by installing it between solenoid valve and actuator. 3. Port with a pressure gauge or a plug can be used as an OUT port.
A unique positioning mechanism allows accurate installation and removal of tubing with ease even in a hardto-see locations, while preventing piping errors when reconnecting. Plug Holder Socket Plug case Irregular shape permits engagement in a proper position.
To connect a drain discharge pipe, use a pipe with a minimum bore of 10, and a maximum length of 5 m. Avoid using a riser pipe.
If the drain bowl is difficult to check and remove, it is recommended that a drain bowl with the auto-drain option be installed.
Can be used for a wide range of pressures from low vacuum up to a pressure of 1.0 MPa. The use of a special profile ensures sealing and reduces resistance when the tube is inserted. Guide Collet Can be used in copper-free application. Body O-ring Flame resistance (Equivalent to UL-94 standard, material V-0) Stud Tube Effective when piping in a confined space.

Do not use in a low pressure application (such as a blower). F.R.L. unit has its own minimum operating pressure depending on the equipment and is designed specifically to function with compressed air. If used below the minimum operating pressure, a loss of performance and malfunction can occur. Please contact SMC if an application under such conditions cannot be avoided.
In such a case, adjust the open angle of its bleed valve to lower the pressure a bit inside the bowl, so that drainage will run through easily. Selection Caution 1. The maximum dischargeable drainage rate is 400 cc/min. If the product is operated in excess of this value, there is a risk of causing the drainage to flow over to the outlet side. Piping Caution 1.
Loosen the cross-recessed head machine screw by using a Phillips screwdriver to remove the plate from the case. 2. After exchanging connectors in desired places, fix the plate to the case by using a Phillips screwdriver. 3. After shifting the bolt for bracket to the outside, tighten the bolt by a Phillips screwdriver to fix the socket case.
If the drain bowl is difficult to check and remove, it is recommended that a drain bowl with the auto-drain option be installed.

Use a nylon or polyurethane tubing for general industrial water. If using a softnylon tube, it may be shrunk and cause air leakage or the tube may be loosen out. 2. The value of the max. operating pressure is at a temperature of 20C. Refer to the burst pressure characteristics curve for other temperatures.
