sequence valve

 

1. Introduction of sequence valve

Sequence valve is a valve that controls the sequence of actuators in a system with more than two branch loops according to the pressure of the loop. The valve can also be used as a unloading valve and a back pressure valve.

2. Characteistics of sequence valve  

The basic function of sequence valves is to control the sequential actions of multiple performing elements, depending on their functions,

They are called sequence valves, back pressure valves, unloading valves and balance valves respectively. The performance of sequence valves is basically the same as that of relief valves, but due to different functions, there are special requirements for sequencel valves:

1) in order to realize the sequence action accurately, it is required that the pressure regulation accuracy of the sequence valve is high and the deviation is small;

(2) for the accuracy of sequential action, small leakage is required when the valve is closed;

For unidirectional sequential valves, the reverse pressure loss and forward pressure loss should be smaller. The main functions of sequential valves are:

(1) controlling the sequential actions of a plurality of elements;

(2) used in voltage control circuit;

(3) to prevent the cylinder piston from falling freely due to self-weight for the purpose of balancing the valve;

4) using the external control sequence valve as the unloading valve, so that the pump can be unloaded;

Use internal control sequence valve as back pressure valve.
