CHECK VALVE

Q.

Do you have the check valves (VC-P-4-E) with no oil specifications?

A.

Since VC-P-4-E, resinous check valve, does not contain oil, the standard specification is no oil type itself.

A.

It's applicable for various sizes as the specialized products.
We have the record of the cylinder with the diameter of φ600mm at the largest.

TERMS

Q.

What are BF diaphragms?

A.

Their shapes are like silk-hats, and covered with rubber on the synthetic fibers, operating diaphragms parts are designed to be very thin. The characteristics are quite natural rolling action by diaphragms and their superior pressure resistance.

Q.

What is BF cylinder?

A.

They're air cylinders using BF diaphragms. The diaphragms' rolling action permits us to solve the big problems of air-leakage and friction.

Q.

What is operating friction?

A.

The friction resistance is caused by cylinder's action. The larger the operating resistance value becomes, the more hysteresis-loss becomes larger. Then the rod does not move smoothly.

BF CYLINDERS

Q.

Please inform the dimension (measurement table) of old type of cylinders (BFSAS, BFDA).

A.

Please download old type of cylinders' catalogs from herea. (PDF/Japanese)

Q.

Are there any differences between old types of cylinder (BFSAS, BFDA) and new types (FCS, FCD) to interchange them?.

A.

Old types and new types are different from each other in their outside dimensions. Old types are tubular type and new types are rectangular parallelepiped types in outside.
Besides, there are some differences in the length of the cylinder and inlet port, or in other dimensions.
Since it became a new model and spigot joint for positioning was added to the both ends of the cylinder, it is impossible to attach the brackets for the old models.
Please confirm old and new BF cylinder comparison table for details.
Please download the comparison table of old and new type of BF cylinder from herea. (PDF/Japanese)

Q.

Please inform the weights of cylinders and sizes of carton boxes.

A.

Please refer the weight and size table for the weight of cylinders and the sizes of carton boxes at the time of packing shipment from the following link.
Please inquire about the items which are not referred on the table.

Please download the weight and size table of cylinders and carton boxes from herea. (PDF/Japanese)

Q.

Please provide us handling instructions or setup instructions.

A.

Although BF cylinder is a cylinder which was equipped with many features unlike the general packing cylinder, in order to fully utilize the function and to have it used for a long time, there are some notes in handling or installation. Please download handling instructions of BF cylinders from herea. (PDF/Japanese)

Q.

What are the characteristics of BF diaphragms?

A.

It's available to have the following features by using BF diaphragm unlike packing.

1. Almost no air leak.
2.Responsive to minute pressure variations.
3.Virtually no hysteresis-loss in movement

Q.

What is the value of operating frictions?

A.

As they have the different sizes each other, please inquire each time you need.
Please understand that there is a cylinder under measurement still depending on the sizes.

Q.

How long is the life-span?

A.

Since it varies depending on the use (a working pressure range, a stroke, environment, etc.), it cannot be referred generally. However, it is also possible to set up and real-measure the similar environment according to the customer's request.

Q.

What are the differences between single action and double action types?

A.

A single action type means the cylinder which exhausts the air to single-sided one way. A double acting type means the cylinder drives in the direction of both sides (pressure, inlet). When you make the rod pushed out by the single action type draw in without air pressure, please choose the cylinder with a spring (S1).

Q.

What is the difference between FC series and SC series?

A.

FC series is a standard cylinder of our company which uses dry bearings for bearings.
SC series is the cylinder for which the linear ball bearing is used.
Increase of operating resistance to horizontal load can be suppressed more than FC series.

REGULATORS

Q.

Even when RS is fully opened, air will bleed. Is it a trouble?

A.

RS and RR always need the air to bleed because they are bleeding type of regulators themselves.
For this reason, the air bleeds even when it's closed completely.
Also RT has the same structure, the air flows out even in the time it's closed completely.

Q.

What is the meaning of each model designation (RS-3-2)?

A.

"RS"… Model types (Super precision regulators)
"8" … Set pressure range (840kPa at maximum)
"2" … Pipe port size (Rc1/4)

Q.

Is every fluid available in regulators?

A.

The specifications for our regulators permit inactive gas.
Please withhold use of combustible gas.

REGULATORS FOR CLEAN ROOM

Q.

What are the differences between RS, RR Series and the products for clean rooms?

A.

Corresponding to clean room, tap processing is given to the exhaust port at the time of bleeding, and it has the structure whose air does not leak in the clean room,
Moreover, each part article performs pure water washing, and they never be contacted by bare hands at the time of assembling.

ABOUT RELIEF VALVES

Q.

Are they complete non-bleed models?

A.

Since their main purpose is relief, the amount of leaks is not zero.
The leak of about 10 or less mL/min occurs.
