It is widely used in situations where it is frequently opened. The full diameter has zero leakage, and the packing adopts an integral molded rubber body to achieve zero leakage in the upper seal. The replaceable integral polyurethane valve liner and stainless steel gate save the maintenance cost of the valve, and are widely used in fields such as mining slag discharge, electricity, papermaking, and urban sewage treatment.

Product advantages:

1. The overall medium flow component is lined with polyurethane, which is wear-resistant and has a long service life.

2. Full bore, zero leakage.

3. The filling material adopts an integral molded rubber body to achieve zero leakage in the upper seal.

4. The replaceable integral polyurethane valve liner and stainless steel gate save maintenance costs for the valve.

5. The product is widely used in mining slag discharge, electricity, papermaking, urban sewage treatment and other fields.

Product Features:

1. The wear-resistant polyurethane valve liner cast as a whole provides an ultra long wear life. At the same time, the D-ring and valve liner are molded together to keep the valve plate clean during valve operation and prevent solid particles from entering the valve chamber area.

2. When the valve plate is closed, the flow rate of the slurry increases, and the edge of the valve plate changes the direction of the slurry to enter the molded polyurethane valve seat area. This vortex causes the valve to flush the valve seat to ensure that there is no blockage at the bottom of the seat, achieving * sealing.

3. The wear-resistant properties of the rigid stainless steel valve plate and polyurethane valve liner ensure the sealing and service life of the valve.

4. The upper seal adopts an integral die-casting rubber body to achieve zero leakage.

5. The replaceable, integral polyurethane valve liner and stainless steel valve plate save maintenance costs and time for the valve.

Scope of application:

1. Mining: pyrite/iron ore, copper ore concentrate/tailings, gold ore, soda ash, phosphate ore, lead, coal, cement, lime/limestone

2. Sugar making

3. Paper making

4. Slag discharge

5. Electricity, flue gas desulfurization, fuel transportation

Structural features:

1. Full bore: This valve is a full bore valve. After opening, the valve plate * shrinks into the valve chamber, and the valve plate does not directly contact the medium, avoiding malignant erosion at the bottom of the valve plate.

2. Upper seal: The EPDM rubber with integral molding and angled design ensures sealing while providing extraordinary service life.

3. Wear resistant polyurethane lining: The lining is made of integral cast polyurethane elastomer, providing an ultra long wear and corrosion resistance life. Additionally, this lining can be replaced.

4. Valve plate: Made of stainless steel plate, it has undergone solidification aging to achieve hardness, and this valve plate can also be replaced.

Introduction to Knife Gate Valve Products:

Knife Gate ValveThe application scope is very wide, from coal selection, gangue discharge, slag discharge in mines and power plants, to urban sewage treatment; From slurry transportation in cement and paper mills to professional pipelines in food, hygiene, medicine, and other fields. The ultra-thin designed knife gate valve solves the difficult problems of large flow resistance, space occupation, slag accumulation, installation and maintenance of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves and other valves due to its small volume, light weight, small flow resistance, no slag accumulation, easy installation and disassembly. Therefore, a large number of universal shut-off valves and regulating valves have been replaced by knife gate valves.

Product Overview:

Knife shaped gate valves can be equipped with electric and pneumatic actuators. By using accessories such as solenoid valves and proximity switches, they can complete the action control and signal output of opening and closing positions, as well as automatic control of continuous actions. Users can choose according to their actual needs. Widely used in chemical, coal, sugar, wastewater, papermaking and other fields, especially suitable for the papermaking industry.

Features:

Knife gate valve adopts a knife shaped gate plate, which has good shear effect and is suitable for difficult to control fluids such as pulp, powder particles, fibers, etc. It is widely used in industries such as papermaking, petrochemicals, mining, drainage, and food. There are multiple valve seats to choose from, and electric or pneumatic actuators can be equipped according to on-site control requirements to achieve automated operation of the valve. The blade gate valve has a shearing function on its gate plate, which can scrape off the adhesive on the sealing surface and automatically remove debris. The stainless steel gate plate can prevent sealing leakage caused by corrosion.
