PZ973H\P electric knife gate valve Shanghai valve manufacturer

,
) Electric Knife Gate Valve
The electric knife gate valve is equipped with a multi-rotation electric device to make the valve plate move linearly up and down to achieve remote control of the opening or closing of the valve. , the valve body is made of cast steel or stainless steel, the diameter range is ~, the operating temperature is °C, and the nominal pressure is...~. It is used in chemical industry, coal, sugar making, sewage, paper making and other fields. It is especially suitable for regulating and throttling pipes in the paper making industry.

Product Features
Electric knife gate valves are made into two forms: concealed stem and exposed stem according to different diameters (concealed stem~, exposed stem~ ), the fully circular DC channel design has no residue or obstruction. The bottom end of the blade is processed into a blade shape, which has the function of cutting soft materials such as fiber, paper pulp, and wood pulp, and has good opening and closing functions. A hard PTFE scraper is installed on the top of the blade to prevent dust, gravel and other abrasive substances from entering the stuffing box, which can significantly increase the life of the blade. The valve plate is made of stainless steel and finely ground and polished to achieve the best sealing effect. Compact design, small space occupation, light weight, cheap price, easy to install, complete wear-resistant and anti-blocking measures, easy maintenance, convenient use and long life, and the driving device can be selected at will.
The valve body and packing culvert are all precision cast. The valve body is integrally cast with flange type. The material can be selected according to user needs. The sealing ring is made of reinforced polytetrafluoroethylene, which is corrosion-resistant, wear-resistant and non-toxic. Dirty.
The valve plate has a supporting point, which makes the valve plate self-centering very well. When the valve is closed and subjected to back pressure, the valve plate does not deflect.
The knife-shaped pulp gate valve can be equipped with handwheel, manual zipper, spur gear transmission, bevel gear transmission, pneumatic and electric.
The interior of the knife-shaped slurry gate valve can be made into shaped, triangular or pentagonal channels. The gate can be used as an adjustment control.
The connection forms of knife-shaped pulp gate valve include wafer type and flange lug type, and the seals include metal-to-metal hard seal, metal-to-polyurethane, and reinforced polytetrafluoroethylene soft seal.
