[Product Applications]
The PZ673H series pneumatic knife gate valves are applied in various industrial fields, especially in the mining and steel industries - for coal and filter slag slurry, in purification devices - for wastewater, mud, sewage and clarified water with suspended solids, in the papermaking industry - for paper pulp and water mixtures of any concentration, and in power plant ash removal - for ash slurry and other professional piping systems.
[Valve Models]
Common pneumatic knife gate valve models include: PZ673H-10C, PZ673H-16C, PZ673Y-10P, PZ673Y-16P, PZ673F-10P, PZ673F-16P.
[Structure Diagram]

[Product Features]
1. Simple structure, beautiful appearance, full through flow passage and small flow resistance coefficient. When the gate plate is lifted, the sticky substances on the sealing surface are scraped off automatically, removing impurities;
2. The stainless steel gate plate can prevent sealing leakage caused by corrosion. The overall stainless steel material prevents corrosion damage and prolongs the service life;
3. Various piping flange standards and flange sealing surface types can be selected, as well as various driving modes such as manual, worm gear drive, electric, pneumatic and hydraulic drive, to meet the different needs of users.
