Description of knife gate valve:
Manual knife gate valve PZ73X manual gate valve PZ73H manual knife gate valve PZ73F manual knife gate valve PZ73Y wear-resistant knife gate valve PZ73W manual stainless steel knife gate valve / gate valve / gate valve / knife gate valve / knife gate valve system. It adopts knife-shaped gate, which has good shearing effect, and is suitable for hard-to-control fluids such as slurry, powder, and fiber. It is widely used in papermaking, petrochemical, mining, drainage, food and other industries. A variety of valve seats are available, and can be equipped with electric or pneumatic actuators to realize the automatic operation of the valve according to the on-site control requirements. The gate of the knife gate valve has a shearing function, which can scrape off the sticky matter on the sealing surface and automatically remove debris. The stainless steel gate can prevent seal leakage caused by corrosion.
The main feature of knife gate valve:
1. Manual knife gate valve is also called knife gate valve and knife gate valve. It is suitable for pipelines with suspended particles and fibrous materials such as pulp, sewage, coal slurry, ash and cement mixture. plates to cut these mediums.
2. There is actually no cavity in the valve body. The gate moves up and down in the side guide groove, and is pressed tightly on the valve seat by the lug at the bottom. If a higher medium sealing performance is required, an O-shaped sealing valve can be selected. The seat realizes two-way sealing.
3. According to the driving mode, it is divided into manual knife gate valve, pneumatic knife gate valve and electric knife gate valve.
4. The knife-type gate valve is light and flexible in operation, small in size, smooth in passage, small in flow resistance, light in weight, easy to install and easy to disassemble, with a nominal size of DN50 ~ DN1200, and can be operated at a working pressure of 0.6MPa ~ 1.6MPa and an operating temperature of ≤ 100°C. work normally.
5. The gate plate of the knife gate valve has a shearing function, which can scrape off the sticky matter on the sealing surface and automatically remove sundries.
6. Stainless steel ram can prevent seal leakage caused by corrosion.
Remarks on product parameters:
(1) The price of the knife gate valve varies with the caliber, material and pressure.
(2) Connection form: pair clip (torx, lug type, single clip type), flange, etc.
(3) Transmission mode: manual, gear transmission, pneumatic, electric, electro-hydraulic, etc.
(4) Caliber: DN50 ~ DN1200; Pressure: 1.0MPa ~ 2.5MPa; Temperature -29°C ~ +650°C.
(5) Materials include: carbon steel, stainless steel, ductile iron, gray cast iron and other special steels.
