ZDFQ trip solenoid valve, also called multi-function solenoid Industrial Valves including manual function, signal feedback, normally open, explosion-proof, schedule control and large diameter zero pressure and pressure to start. 1. Manual type: divided into turbine manual open, specific application in the absence of pressure piping and the low pressure pipeline. Through the thread type of movement up and down. 2. Exhaust pressure type manual control: manually discharge Industrial Valves internal pressure forming pressure to achieve the goal, this way is suitable for pressure piping. Reflect for turbine different is a kind of way is convenient save Labour, namely the installation manual Industrial Valves on the valve outlet. 3. Flow control: ZDFQ trip solenoid valve can be actual through the flow control valve, so as to achieve the required purpose. 4. Signal feedback: can be divided into two kinds, one kind of the feedback signal control type, another kind of control under the type of feedback signals. Control type that is installed on the trip switch of the guide head part, when moving up through the coil moving core by activity core is close to the static iron core, triggering travel switch short-circuit current signal. Under control, that is installed on the bottom of the valve, suitable for small diameter DN65 - DN100 more convenient in operation and replacement. Structure: made up of inner shaft rod and cover the basic form, rod screw for the whole state, external manual wrench can move up or down by rotating shaft lever. When the valve is fully open by shaft rod movement moves down, the piston to move upward in a free travel within the scope of the degree of control to open, in this premise is that the product is only applicable to the piston structure. Through flexible operation can make the valve fully closed
is emerging as one of the most popular flow control valve, moving beyond its resilient valve benefits, with conclusive scientific evidence suggesting the positive role play in y gate valve.
