Word list of SMC Pneumatic Product catalogs

1. Maximum operating pressure variation

The maximum pressure variation (the most notable difference between the inlet and outlet pressure) which is allowed for operation, with the valve closed or open. When the outlet pressure is 0 MPa, this becomes the maximum operating pressure.

2. Minimum operating pressure difference

The minimum pressure gradient (the most notable difference between the inlet pressure and outlet pressure) needed to keep the primary 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. Explanation 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]

Electric Language

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 temporarily generated by shutting off the power in the shut-off area.

3. Enclosure

A degree of protection well-defined in the “JIS C 0920: Waterproof test of elec machinery/appliance and the degree of defense against the intrusion of solid foreign objects”.

Verify the degree of protection for every product.

Others

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 specified here is utilized under varied operating conditions, its compatibility with express equipment must be decided by the person that designs the equipment or decides its specifications based mostly on required enquiry and test results. The anticipated performance and safety ensure of the equipment will be the responsibility of the person 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.

The utilization of SMC catalog products with production equipment for the construction of weapons of mass eradication or any other weapon is strictly restricted. Pneumatic Dotcom
