REXROTH solenoid valve characteristics:
1.Rexroth solenoid valve and all stainless steel solenoid valve;For strongly corrosive media,isolation diaphragm type must be selected.Neutral medium,it is also advisable to use copper alloy as the valve housing material for electromagnetic valves.Otherwise,rust debris often falls off in the valve housing,especially in situations where the action is not frequent.Ammonia valves cannot be made of copper.
2.Explosive environment:Corresponding explosion-proof grade products must be selected,and waterproof and dustproof varieties should be selected for outdoor installation or dusty environments.
3.The nominal pressure of the solenoid valve should exceed the high working pressure inside the pipe.
The Rexroth solenoid valve is a step by step direct pilot type solenoid valve,which can be opened or closed according to the different states during power outage,

Rexroth solenoid valves can be divided into normally closed solenoid valves and normally open solenoid valves.Normally closed solenoid valve,after the coil is energized,
The rexroth solenoid valve armature first drives the auxiliary valve plug to lift under the action of electromagnetic force,
The fluid on the main valve cup of the rexroth solenoid valve flows away through the auxiliary valve,
The Rexroth solenoid valve reduces the pressure acting on the main valve cup,
When the pressure on the main valve cup of the rexroth solenoid valve decreases to a certain value,
The rexroth solenoid valve armature drives the main valve cup and uses the pressure difference to open the main valve cup,
Rexroth solenoid valve medium flow.After the coil is powered off,the electromagnetic force disappears and the armature resets due to its own weight falling.(Function of solenoid valve)
The Rexroth solenoid valve relies on medium pressure to tightly close the main and auxiliary valves.Normally open solenoid valve,
After the Rexroth solenoid valve coil is energized,due to the suction force,the moving iron core moves downwards and the auxiliary valve plug is pressed down,
The secondary valve of the Rexroth solenoid valve is closed,and the pressure inside the main valve cup rises.When the pressure reaches a certain value,
The pressure difference between the main valve cup of the Rexroth solenoid valve is the same,but due to the electromagnetic force,
