PZ573W stainless steel clamp type umbrella gear knife shaped gate valve

Product Introduction:

The umbrella gear knife type gate valve is a pneumatic driven, clamp type connection, rising stem parallel rigid single gate valve. The valve seat sealing surface is made of hard alloy and polytetrafluoroethylene. The models are PZ573X, PZ573H, PZ573F, PZ573Y, PZ573W, with a nominal pressure of PN10~16. The valve body material is carbon steel or stainless steel, and it is a gate valve with slag discharge function. The umbrella gear knife type gate valve adopts a fully circular channel design, and is equipped with polytetrafluoroethylene, a scraper, and a wear-resistant folding cone made of polyethylene or Ni wear-resistant cast iron installed at the inlet end of the knife plate. Multiple flushing ports can be set around the valve body. The bottom of the blade is processed into a cutting edge with high smoothness, ensuring good sealing.

Usage and characteristics:

PZ573H umbrella gear knife type gate valve is widely used in various fields such as chemical industry, coal, sugar production, sewage, papermaking, fly ash treatment, bulk material transportation, food and beverage industry, and under harsh environmental conditions. It is an ideal sealed valve. Knife gate valves are particularly suitable for regulating and throttling pipelines in the paper industry. According to the needs, multiple flushing ports can be set around the valve body, which can be directly flushed with air, steam or water to prevent sediment from gradually accumulating. It is particularly suitable for fluids with difficult input.

1. Adopting a clamp type structure, it has a small volume, light weight, low flow resistance, and is easy to install and maintain.

2. A completely open channel can prevent the medium from depositing inside the valve.

3. The newly developed U-shaped sealing ring can ensure good sealing performance of the valve.

4. The external sealing of the gate is achieved by a sealing strip with elasticity embedded in the valve body, which can be adjusted with the help of screws and pressure plates.
