Pressure Terminology section : Pneumatic equipment

1. Maximum operating pressure variation

The maximum pressure gradient (the huge difference between the inlet and outlet pressure) which is permissibly for operation, with the valve (open/closed). When the outlet pressure is 0 MPa, this becomes the maximum operating pressure.

2. Minimum operating pressure variation

The minimum pressure differential (the greatest difference between the inlet pressure and outlet pressure) required to keep the key valve stable operated.

3. Maximum system pressure

The maximum pressure that could be applied in the pipelines. (Line pressure) [The pressure gradient of the solenoid valve portion must be less than the maximum operating pressure differential.]

4. Proof pressure

The pressure in which the valve must be withstood without a drop in performance after holding for 1 minute under prescribed pressure (static pressure) and returning to the operating pressure range. [Value under the prescribed conditions]

e- Words

1. Clear power (VA)

Volt-ampere is the product of voltage (V) and current (A) .Power consumption (W) : For AC, W = V A cos. For DC, W = VA.Note) cos shows power factor. Cos = 0.6

2. Surge voltage

A high voltage which is briefly generated by closing off the power in the shut-off area.

3. Enclosure

A degree of protection outlined in the "JIS C 0920: Water-proof test of electrical machinery/appliance and the degree of cover against the intrusion of solid foreign objects".

Determine the degree of protection for each product.


1. Material

NBR: Nitrile rubber

FKM: Fluoro rubber "Product name: Viton, Dai-el, etc.

EPDM: Ethylene propylene rubber

2. Oil-free treatment

The degreasing and washing of wetted parts.

3. Passage symbol

In the JIS symbol In and Out are in a blocked condition, but essentially in the case of reverse pressure (OUTgt;IN), there is a limit to the obstructing. is used to suggest that obstructing of reverse pressure is not possible

Since the product stated here is employed under diverse operating conditions, its compatibility with specific hardware must be decided by the person who designs the kit or decides its directions based on obligatory research and test results. The expected performance and safety assurance of the clobber will be the responsibility of the individual that

has determined its compatibility with the product. This person should also steadily review all specs of the product talking about its latest catalogue info, with a view to giving due consideration to any chance of clobber failure when configuring the equipment.
