note: buy forged steel pneumatic valve
, according to the purpose of web site, understand the relevant laws, regulations, specifications, standards, guidelines, and approved by both sides with the various demands of the pneumatic valve allows you to use;
and confirm the pneumatic valve working conditions, as the media, working pressure, medium temperature;
, determine the DN (with the nominal pipe diameter matching: Mm) , nuclear power source ( “） ;
and determine the pipeline connection: flange, ( ) Thread, welding clamp, clamp, the card sets, etc. ;
, pneumatic valve operation, in order to determine the drive mode: manual, worm gear, pneumatic, electric, hydraulic, electromagnetic effect, such as electro-hydraulic;
and determine the type of pneumatic valves, pneumatic valve, brake by the pneumatic valve, pneumatic valve, throttle plunger pneumatic valves, pneumatic ball valve, butterfly, pneumatic valve, pneumatic diaphragm valve, pneumatic valve, cock check pneumatic valve, pneumatic valve, safety hydrophobic pneumatic valve, pneumatic valves and other special pneumatic valves;
