Electro-hydraulic gate valve, flat gate valve, pneumatic flapper valve, manual closed gate valve
Electro-hydraulic knife gate valve is made of electro-hydraulic device with knife gate valve, realize electric control hydraulic, at the same time with the signal output control, can realize remote automatic control, is a kind of intelligent automatic control knife gate valve.
Electro-hydraulic gate valve is a kind of rotary valve for opening and closing. Electro-hydraulic gate valve is composed of electro-hydraulic device and ball valve. Electro-hydraulic gate valve is widely used in petroleum, chemical industry, electric power, oil refining, papermaking, metallurgy, building materials, light industry and other industrial sectors (gas, liquid, steam, sewage, and high viscosity with fiber and fine particles) medium for opening and closing control.
Flat Valve
The plate valve is the main equipment for controlling the flow rate of powder, crystal and small particle materials. Flat valves are widely used in metallurgy, mining, building materials, food, chemical and other industries. Flat valve is equipped with pneumatic, electric, electro-hydraulic push rod as a driving device, is to control the size of the flow, cut off quickly equipment.
Structural features:
Flat valve products have the characteristics of simple structure, smooth operation, excellent sealing performance, small local resistance loss, fast cut-off, convenient maintenance, and not easy to deform.
Performance parameters:

Pneumatic board valve
Pneumatic valve is mainly used for ventilation and dust removal, wind conveying and exhaust system on the pipeline regulation and solid powder conveying regulation and cut off.
Structural features:
The pneumatic flapper valve has simple structure, free operation, flexible sliding of the valve plate, reliable sealing performance, low local resistance loss, good adjustment performance, convenient maintenance and replacement, and is not easy to deform. It overcomes the large air leakage and fast deformation of the old flapper valve. Difficult to adjust.

manual closed gate valve:
Manual airtight gate valve is a new generation of gate valve products improved by combining user feedback and years of production practice in Jiangsu Zhongyuan. Manual closed gate valve is widely used in building materials, metallurgy, mining, chemical industry, food and other industries, is the ideal equipment to adjust or close the grinding material flow.
Structural features:
The manual closed gate valve has strong sealing performance, convenient and flexible starting, no pollution in the transmission part, no grinding effect, long service life, no leakage, convenient installation, and is not affected by the angle, can be opened and closed at any time, change the material flow, and meet the system Use conditions.
