Control and signal output can also be completed Automatic control of continuous action,
The main body is made of cast iron, cast steel, stainless steel, etc., with diameters ranging from ~
The products are widely used in chemical industry, coal, sugar refining, sewage, paper making and other fields,
It is an ideal sealing valve. It is especially suitable for regulating and throttling pipes in the papermaking industry.
, Use dual electric control three-position five-way solenoid valve to control the pneumatic knife gate valve cylinder, and use three-position switch to control the gate valve to stay at the upper limit, lower limit and any position.
When the gate valve stays at the upper limit and lower limit positions, the limit switches at the upper limit and lower limit positions send out a set of normally open or normally closed independent signal contacts. Can be used as status indication.
When the gate valve stays at the upper limit and lower limit positions, the limit switches at the upper limit and lower limit positions automatically cut off the power supply to the corresponding control coil of the solenoid valve. In this way, when the gate valve stays at the upper limit and lower limit positions for a long time, the electronic control coil of the solenoid valve is not energized, which can prevent the solenoid coil from heating up, increase the service life of the solenoid valve, and greatly improve reliability.
When the gate valve stays at the upper limit and lower limit positions for a long time, the air source is cut off and no air is consumed. However, the air pressure of the locking valve cylinder is still maintained in the cylinder, ensuring reliable parking.
. During the cylinder switching process, if the control power supply is cut off, the inlet and outlet air of the cylinder will also be cut off at the same time. The air pressure of the locked valve cylinder will still remain in the cylinder. If there is no leakage in the cylinder piston, solenoid valve and joints, the gate valve can be in Stay anywhere for a long time.
