The star of pneumatic valve products - — The role of the pneumatic valve sequence

the order of the pneumatic valve main functions are:
, used for holding circuit;
, make back pressure pneumatic valve with pneumatic valve control order;
, sequential control multiple elements;
, with external control pneumatic valve, pneumatic valve in order to do unloading pump unloading;
and prevent falling caused by dead weight oil cylinder piston pneumatic valve with do balance; Sequential pneumatic valve control is the basic function of multiple components of the order of the action, according to its different functions, called sequential pneumatic valve, back pressure pneumatic valve, pneumatic unloading pneumatic valve and balance valve.
order the performance of the pneumatic valve and the overflow pneumatic valve basic same, but because of the different functions, the sequence of pneumatic valve and its special requirements such as: in order to make the executive element to realize sequential accurately, required sequence of the pneumatic valve high regulating voltage accuracy, small deviation; In order to the accuracy of the sequential, requires leakage in pneumatic valve closing small; For one-way pneumatic valve in order to reverse the pressure loss and positive pressure loss value should be smaller.
order pneumatic valve is a kind of use need to pay special attention to the product, if its on-off characteristic is very poor, in the larger flow pressure is too great, circuit efficiency is very low; Rev low pressure pneumatic valve, pressure is lower than the set pressure before the leak, actuator caused by misoperation. So for the user, in order of pneumatic valve need special attention when using the on-off characteristic.
