Performance and Characteristics of Stainless Steel Pneumatic Knife Gate Valve

1、 Performance of stainless steel pneumatic knife gate valve:

1. Nominal pressure: PN1.0~1.6Mpa

2. Diameter range: DN50~DN2000

3. Connection type: round clamp, quincunx flange type, lug type, flange type, etc

4. Transmission mechanism: pneumatic actuator

5. Main material: CF8

6. Ram material: 2Cr13.201.304.316.316L

7. Applicable temperature: ≤ 300 ℃

8. Leakage grade: D (liquid 0.1 × DNmm3/s). Hard seal (zero leakage). Soft seal (zero leakage)

9. Sealing type: W

10. Packing seal: oil filled PTFE packing

11. Applicable medium: It is applicable to the chemical treatment of coal preparation, slag discharge, food, paper making, medicine, chemical industry and other pipelines in the mine power plant. It is used to connect or cut off the cement slurry, gold ore powder, ore, slag, slime, pulp, wood pulp, tailings, fiber, dust, sewage, sedimentation tank, asphalt, silo outlet and other media in the pipeline.

2、 Features of stainless steel pneumatic knife gate valve:

1. Ultra short structure length, material saving, can greatly reduce the overall weight of the pipeline system;

2. It occupies less effective space, can effectively support the pipeline strength and reduce the possibility of pipeline vibration;

3. The ram is made of austenitic stainless steel, which greatly improves the corrosion resistance and can effectively prevent seal leakage caused by ram corrosion;

4. The upper sealing filler is flexible PTFE, with reliable sealing and convenient and flexible operation;

5. The ram has the function of knife switch, which can effectively cut off all kinds of sundries in the medium.

3、 Overview of stainless steel pneumatic knife gate valve:

DELOCKE Lock stainless steel pneumatic knife gate valve has the shearing function, which can scrape the adhesive on the sealing surface and automatically remove the debris. Stainless steel ram can prevent seal leakage caused by corrosion.

The stainless steel pneumatic knife gate valve can be completed by the action control of closing two positions and the automatic control of signal output or continuous action with accessories such as solenoid valve and proximity switch. Users can be selected according to actual needs. It is widely used in chemical industry, coal, sugar making, sewage, paper making and other fields, and is an ideal sealing valve. It is especially suitable for the paper industry to adjust and throttle the pipes.

4、 Stainless steel pneumatic knife gate valve product maintenance:

1. Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.

2. The double ram gate valve shall be installed vertically (i.e. the valve stem is in a vertical position and the hand wheel is at the top).

3. Before opening, open the gate valve with bypass valve (balance the pressure difference between inlet and outlet and reduce the opening force).

4. Install the gate valve with drive mechanism according to the product manual.

5. If the valve is opened and closed frequently, lubricate it at least once a month.
