Solenoid valve selection should first follow the safety, reliability, applicability and economy of the four principles, followed by six aspects of the on-site conditions (that is, pipeline parameters, fluid parameters, pressure parameters, electrical parameters, Special requirements to choose). Selection basis: First, according to the selection of solenoid valve parameters: Path Specifications (ie, DN), interface mode 1, in accordance with the size of the pipeline diameter or flow requirements to determine the path (DN) size. 2, interface, general> DN50 flange interface to choose, ≤ DN50 can be freely selected according to user needs. Second, select the solenoid valve according to the fluid parameters: Material, temperature group 1, corrosive fluid: Corrosion-resistant solenoid valves and stainless steel should be used; Super clean fluid consumption: should choose food-grade stainless steel solenoid valve. 2, high temperature fluid: To choose the use of high temperature resistant electrical materials and sealing materials manufactured solenoid valve, but also to choose the type of piston structure. 3, the fluid state: as large as a gas, liquid or mixed state, especially when the diameter greater than DN25 must be distinguished when ordering. 4, fluid viscosity: usually below 50cSt can be arbitrarily selected, if more than this value, then the choice of high viscosity solenoid valve. Third, select the solenoid valve according to the pressure parameters: Principle and structure Variety 1, nominal pressure: This parameter and the meaning of other common valves is the same, is based on the pipe nominal pressure to be set. 2, working pressure: If the work pressure is low, you must choose the principle of direct acting or step-by-step direct acting; minimum working pressure differential above 0.04Mpa direct acting, step by step direct acting, pilot can be used. Fourth, the electrical options: voltage specifications should be preferred AC220V, DC24 more convenient Five, according to the duration of work to choose from: normally closed, normally open, or sustainable power 1, when the solenoid valve needs a long time to open, and the duration Excessive closing time should be used normally open type. 2, if the opening time is short or open and close time is not long, then choose the normally closed type. 3, but some for security conditions, such as furnaces, kiln flame monitoring, you can not choose the normally open, should be elected long-term power type. Six, according to environmental requirements to choose auxiliary functions: Explosion-proof, non-return, manual, water fog, water pouring, diving; 1, explosive environment: must choose the appropriate level of electromagnetic valve (I: d II BT4, d II CT5 , Ex m I / II T4). 2, when the fluid in the tube backflow phenomenon, you can choose our company OK71-N, OK72-N series with check-back function solenoid valve. 3, when the need for on-site manual solenoid valve operation, you can choose my company OK71-S, OK72-S series with manual function solenoid valve. 4, open-air installation or dust should be used more occasions waterproof, dustproof varieties (protection level above IP54). 5, for the fountain must be used diving solenoid valve (protection level above IP68).
A Pedal Go Karts is usually comes with four wheels and
very strong metal frame with powder coated. Four-wheel Pedal Go Kart is
the most popular kart, and also we have three-wheel pedal go karts for your choice. Your logo also allowed to show on the go kart.
Features of our pedal go kart:
1. robust metal frame;
2. freewheel &reverse gear;
3. high quality Pneumatic Rubber Tyre;
4. adjustable steering bar and seat for greater comfort;
5. plastic mudguards with reflectors;
6. five colors for your choice.
You can have fun with our kart on the sand beach, or in the park, on the any where you want.
Also we have two seats pedal go karts, so that you can have fun with your family or friend.
If you have a pedal go kart that sell very good in your market. And you
can not find a supplier to make it for you. Don`t worry. Please contact
us, and show us the picture and size, we will do it for you.
Our pedal go karts are all with CE certificate and
sell to many countries. We have QC to control the quality and engineer
to update new kart. If you are hesitate to place a order, we can send
you a sample to check the quality first.
