Adjustment of the pneumatic valve marks, packaging and storage requirements

. Pneumatic valve body ( M）
regulating pneumatic valve pneumatic valve body shall be cast out or out of the said medium flow direction arrow ( No flow requirements except) Manufacturing, the abbreviation of pneumatic valve body material symbols, felt logo or trademark, melting and nominal pressure, nominal size logo. Can also sign in with the pneumatic valve body firmly fixed sign board.
note: sign board definition (GB/T. — In the. 。
。 Nameplate signs ( M or S)
should be fixed on the actuator position nameplate, and mark:
a factory name or factory standard ( M） ；
b product model ( M） ；
nominal menstruation (c M） ；
d nominal pressure ( M） ； Operating temperature (
e Only in some special cases, not to the nominal pressure and flange for signs become mandatory flag) （ S or M) ；
spring pressure range (f Cutting off for signal pressure range), （ S） ；
g rated stroke ( S） ；
h rated flow coefficient ( S） ；
I flow characteristic ( Cutting off not) （ S） ；
j pneumatic valve body material ( M） ； Design a number (
k Can also be marked on the nameplate of independence) （ S） ；
l product manufacturing number ( M） ；
m product manufacturing time ( S） 。
for small norms regulating pneumatic valve, due to restrictions on the size of nameplate, unable to accommodate all signs, allowed to omit part of the logo, but it must be on the nameplate signs have a, b, h, k, l, m. Other mandatory sign: c, d, j should mark on the pneumatic valve body.
note: M = force; S = added.
note: on the small norms regulating pneumatic valve sets minimum marks is to quickly identify parameters.

packing regulating pneumatic valve before packing all without coating layer outside the processing surface should be coated with anti-rust oil or shall adopt other measures for rust prevention, pneumatic valve hole out, entrance and signal transmission pipe thread hole should be seal mouth, and shall be in accordance with the GB/T properly packed, guarantee is not damaged during transportation.
along with the regulating pneumatic valve packing technology file:
a, the factory quality certificate.
b product specification c packing list


storage regulating pneumatic valve should be stored in the air temperature is ℃ ~ ℃, relative humidity is no more than % of the interior, the air should contain no corrosion to adjust the harmful impurities of pneumatic valve.
