A gate valve, an overview:

PZL43H series Sprocket knife type valve Has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation, easy disassembly and other advantages, can be in 1.0MPa-2.5MPa working pressure, working temperature of -29-550 DEG C under normal use.
PZL43H series chain knife type valve: suitable for general petrochemical industry, cement paper, the powder and other categories of environmental protection industry in the body and the slurry type fluid. Knife type gate valve gate with the shear function, can scrape the surface of the adhesive seal material, automatically remove debris, stainless steel gate plate can prevent the corrosion and leakage of the seal by.
Two, Sprocket knife type valve Product features:
1, ultra structure length, material saving, can make the pipeline system greatly reduce the overall weight
2, small occupied space, can effectively support the pipeline strength, can reduce the possibility of pipeline vibration
3 gate, the selection of austenitic stainless steel, corrosion resistant performance is greatly improved, which can effectively prevent the gate seal leakage caused by corrosion
4, on the packing made of flexible PTFE, reliable sealing, flexible operation
5, the gate with the knife, can effectively brake off all kinds of debris in the medium

Four, Sprocket knife type valve Install and use:
1, the installation must be inspected before the valve cavity and the sealing surface and other parts, there is dirt or sand does not allow attachment;
2, all bolts evenly tightened requirements;
3, check the packing requirements of pressed parts, both to ensure the tightness of packing, but also to ensure the open and flexible plate;
4, the user must check valve type before installing the valve, connect the flow of medium size and attention to ensure consistency with the requirements of the valve;
5, the user to install the valve, must be necessary to install the valve drive space dying;
6 wire drive device shall be carried out according to a circuit diagram;
7, the valve must be regularly maintained, not free to collision and extrusion, so as not to affect the sealing performance.
