The reversing valve has multi-directional adjustable channels,The fluid flow direction can be changed in time,SNS pursues high efficiency and keeps updating, launched a ZDV series automatic reciprocating valve.
Ordinary reversing valves generally require external signals to control the reversal of the gas path, while the ZDV series automatic reciprocating valve completes reversing by the pressure difference between the air outlet and the exhaust port, and does not require external signal input. Therefore, in some occasions where only the cylinder is required to perform cyclic reciprocating motion, the cost of the gas circuit can be effectively saved, while the use of electrical components can be avoided, and the production safety can be improved.
The valve automatically changes direction, no need to connect to electricity, no additional controller, can make the cylinder realize automatic reciprocating movement.Before the automatic reciprocating valve is restarted each time, it is necessary to ensure that the spool has been switched in place, and the spool can be in place by pressing the copper button column.Use the pressure difference to balance the direction change.
When the pressure difference is insufficient, the positive pressure will push the spool to change direction, so it must be used with an adjustable muffler to ensure the pressure difference. If the adjustable muffler is not used, it may lead to unstable commutation Or do not change direction.
Because the pressure difference is used in the reversing process, the cylinder does not have to move to the end to automatically change direction. If the cylinder is stuck in motion, or the cylinder is used with a heavier load and slower speed, the pressure difference will disappear prematurely, which will cause ZDV to advance. Reversing.When controlling the cylinder, it is not allowed to install the speed control joint on the cylinder to adjust the speed, which will affect the automatic commutation effect.
