PZ43H Plum Blossom Knife Gate Valve

Brief introduction of PZ43H plum blossom knife gate valve: The opening and closing part of the knife gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The knife gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge. The wedge angle varies with valve parameters, usually 50.

Products Details

PZ43H plum blossom type knife gate valve advantage:
1.The sealing surface of the gate can be lifted, and the adhesives on the sealing surface can be scraped off, and the debris can be automatically removed
2.Stainless steel gate can prevent seal leakage caused by corrosion
3.The overall stainless steel material can prevent corrosion damage
4.The short structure length can save raw materials, installation space, and also effectively support the strength of the pipeline
5.The scientific upper seal packing design makes the upper seal safe, effective and durable
6.The triangular bracket saves raw materials and ensures the required mechanical properties
7.The guide block on the valve body makes the gate move correctly. The squeeze block ensures effective sealing of the gate
8.The stiffener design of the valve body improves the strength of the valve body

Performance characteristics of PZ43H plum blossom knife gate valve:
1. This valve is suitable for the transportation pipeline of coal powder, ash and slag and other materials in the power plant, metallurgy and cement industries, and plays a role of stop and flow.

2. The valve disc is a hemispherical shell. When the valve is opened, the pipeline has a full diameter, and there is no object in the channel to obstruct the flow of the medium, so that the ash and slag flow more smoothly.

3. The valve body is inlaid with an expandable and contractible rubber seal ring, which shrinks when it is opened, and there is no friction between the sealing surfaces. When it is closed, the seal ring expands and presses against the valve disc to achieve a seal.

4. The metal pressure plate protects the rubber sealing ring to prevent medium erosion. The surface of the valve disc is specially treated, which is resistant to erosion and has a long service life.

5. Pneumatic operation is easy to realize remote control and automatic control.

Installation and use of PZ43H plum blossom knife gate valve:
1. Before installation, check the valve cavity and sealing surface and other parts, and no dirt or sand particles are allowed to adhere
2. The bolts of each connection part shall be evenly tightened
3. Check that the packing parts are required to be pressed tightly, not only to ensure the tightness of the packing, but also to ensure that the plug-in plate opens flexibly
4. Before installing the valve, the user must check the valve model, connection size and pay attention to the flow direction of the medium to ensure consistency with the valve requirements
5. When installing the valve, the user must leave the necessary installation space for the valve drive
6. The wiring of the drive device must be carried out according to the wiring diagram
7. The valve must be maintained regularly, and no collision or squeeze is allowed to avoid affecting the sealing performance

Plum blossom knife gate valve application specifications:
1. Design and manufacture according to GB12235-59
2. The structure length is in accordance with GB12221-89
3. Flange size according to JB/T79-94
4. Valve inspection and test are in accordance with GB13927
