Which four rules should be followed in the selection of Japanese SMC explosion-proof electromagnetic valve

SMC explosion-proof solenoid valve selection in Japan should first follow the four principles of safety, reliability, applicability, and economy, followed by six on-site operating conditions (ie pipeline parameters, fluid parameters, pressure parameters, electrical parameters, Action mode, special requirements to choose).

Japan SMC Explosion-proof solenoid valve chooses according to the pipeline parameter
According to the pipeline parameters, select the diameter of the solenoid valve (DN), the interface mode , and determine the size of the path (DN) according to the size of the inner diameter of the pipeline or the flow requirement.

2. Interface mode, generally> DN50 to select the flange interface, ≤ DN50 can be freely selected according to user needs.

According to the fluid parameters to select the electromagnetic valve material, temperature group 1, corrosive fluid: corrosion-resistant solenoid valve and all stainless steel should be used; edible ultra-clean fluid: should use food grade stainless steel solenoid valve.

2, high-temperature fluid: to choose to use high-temperature electrical materials and sealing materials manufactured by the solenoid valve, but also to choose the type of piston structure.

3, the fluid state: as large as there are gaseous, liquid or mixed state, especially when the caliber is greater than DN25 must be distinguished when ordering.

4, fluid viscosity: Usually below 50CST can be arbitrarily selected, if more than this value, you must use high viscosity solenoid valve.

According to the pressure parameters, select the principle and structure of the solenoid valve. 1. Nominal pressure: This parameter is the same as the meaning of other common VALVES and is determined according to the nominal pressure of the pipeline.

2, the working pressure: If the working pressure is low, you must use straight-acting or step-by-step direct-acting principle; minimum working pressure above 0.04MPA when the direct-acting, step-by-step direct-acting, pilot-type can be used.

Select

electrical voltage specifications should be priority selection AC220V, AC110V, DC24V, DC12V

Normally closed, normally open, or unsustainable. 2. If the opening time is short or the opening and closing time is not large, select the normally closed type.

3, but some of the conditions for safety protection, such as furnace, kiln flame monitoring, can not be selected normally open, should be selected long-term power type.

Japan SMC explosion-proof solenoid valve Accessibility

explosion-proof, non-return, manual, water fog, water washout, Diving 1, explosive environment: to choose the appropriate explosion-proof solenoid valves grade (My company: DIIBT4, DIICT5, EXMI/IIT4).

2. When the fluid in the pipe has a backflow phenomenon, I can choose my PATRON ZS-15 series solenoid valve with non-return function.

3, when the need for manual operation of the solenoid valve on the field, I can choose my PATRON ZS-50 series with manual function solenoid valve.

4, open-air installation or dust more occasions should use waterproof, dust-proof varieties (protection level above IP54).

5, for the ZCST fountain must use submersible solenoid valve (protection level above IP68).

1, when the Japanese SMC explosion-proof solenoid valve requires a long time to open, and the duration of the excess time off should be selected normally open type.
