PZ673TCPneumatic ceramic knife-type gate valveProduct Overview：

Pneumatic ceramic knife gate valves are suitable for opening and closing in pipelines carrying high-hardness particles and mediums with soft particles yet corrosive properties. The product is widely applicable in conveying systems for solid, liquid-solid, and gas-solid two-phase mediums such as ash, sludge, coal slurry, ore slurry, and wastewater, particularly in the coal system of thermal power plants. Manual, pneumatic, electric, and electro-hydraulic interlocking operations can be utilized.

Drive Method.

PZ673TCPneumatic ceramic knife gate valveProduct Features：

Pneumatic ceramic knife gate valve, the disc and seat sealing surfaces are made of structural ceramics, which are wear-resistant, corrosion-resistant, and can withstand high temperatures. The sealing surfaces in contact with the medium are all made of structural ceramic materials, boasting high chemical stability and hardness. As a result, this valve exhibits excellent wear-resistant, corrosion-resistant, and erosion-resistant properties, along with good thermal insulation and minimal thermal expansion. The pneumatic ceramic knife gate valve features full flow at the nozzle without obstructions, possesses strong wear resistance, and ensures tight sealing.

High performance

PZ673TCPneumatic ceramic knife-type gate valveUtilizePrinciple：

The knife gate valve's operating part is the gate plate, which moves perpendicular to the fluid direction. Knife gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling. The knife gate valve mainly consists of the valve body,OComposed of parts such as O-rings, gate plates, valve stems, brackets, etc. The knife gate valve features an integrated clamp structure, which is compact and lightweight; it has a fully open passage to prevent medium sedimentation inside the valve. It employs a replaceable sealing structure, addressing the difficulty of maintenance for conventional slurry valves and knife gate valves. The valve body material has been changed from traditional cast steel to ductile iron, offering better corrosion resistance and effectively extending the service life.

Extended lifespan.

PZ673TCPneumatic ceramic knife gate valveProduct AdvantagesDot:

The gate plate of a knife gate valve has two sealing surfaces. The two sealing surfaces of a commonly used wedge gate valve form a wedge shape, with the wedge angle varying according to the valve parameters, usually being50,The gate of a wedge gate valve can be made as a single piece, known as a rigid gate plate; or as a plate capable of minor deformation to enhance its workability, compensating for the discrepancies in the sealing surface angle that may occur during the manufacturing process. This type of gate is called an elastic gate plate. When a wedge gate valve is closed, the sealing surface can be sealed solely by the medium pressure, meaning that the sealing surface of the gate is pressed against the opposite side of the valve seat by the medium pressure to ensure a tight seal, which is referred to as self-sealing. Most wedge gate valves use forced sealing, i.e., when the valve is closed, an external force is needed to forcibly press the gate towards the valve seat.

Seats, to ensure the sealability of the sealing surface..
