Pressure Terminology : Pneumatic equipment
1. Maximum operating pressure difference
The maximum pressure differential (the biggest difference between the inlet and outlet pressure) which is made allowance for operation, with the valve open or closed. When the outlet pressure is 0 MPa, this becomes the maximum operating pressure.
2. Minimum operating pressure difference
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 can be applied inside the pipelines. (Line pressure) [The pressure variation 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 momentarily generated by closing down 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".
Determine the degree of protection for each 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 & OUT are in a blocked condition, but basically in the case of reverse pressure (OUTgt;IN), there're limit to the block. is used to indicate that block it of reverse pressure might 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.
