Knife gate valve is mainly used for process control in pulp & paper making, slurry, residue discharge and sewage treatment.

Feature:

1. Valve port is in one line with pipeline at full open position with low resiteance;

2. Good tightness, stable performance without vibration and noise;

3. O-ring loaded movable seat to serve as self-compensation with good abrasoin resistance and long service life;

4. Metal seated , PTFE Seated and EPDM Seated desings are available for various process conditions;

5. Independent seat retainer to reinforce Seat;

6. One piece body construction.

Technical specification:

Nominal diameter (mm ): DN80-DN600

Nominal pressure rating: 1.0Mpa, 1.6Mpa, ANSI 150

Instructions for use:
1. When selecting a model, it is necessary to select the appropriate valve material, nominal diameter, etc. according to the actual working pressure, temperature, medium and other requirements.
2. Before installation, carefully check whether the valve is in good condition and whether the operation is flexible, and carry out necessary cleaning and derusting treatment.
3. When using, follow the operating procedures provided by the manufacturer. Do not exceed the working pressure and temperature range of the valve. When opening and closing the valve, it should be smooth and orderly to prevent damage caused by rapid switching.
4. Carry out regular maintenance, remove internal impurities, regular lubrication, etc.
In short, the ductile iron knife gate valve has the advantages of simple structure, convenient operation, high pressure resistance, corrosion resistance, long service life, etc., and is an economical and practical fluid control valve.
