Chain Wheel Operated Non-Rising Stem Knife Gate Valve

Chain Wheel Operated Non-Rising Stem Knife Gate Valve

 
1. The valve adopts an integral design, with low fluid resistance and flexible and convenient operation.

2. The screw drive of the gate valve adopts a double plane bearing design, which greatly reduces the transmission friction and makes the valve open easily and smoothly.

3. The sealing seat of the knife gate valve adopts a movable seal, and the O-ring pre tightening provides pre tightening force to make the sealing seat tightly adhere to the valve disc, greatly reducing leakage. It has an automatic compensation function for the wear of the sealing pair in long-term use, improving its service life.

4. Fixed guide claw, no groove design, not easy to cause medium accumulation or jamming.

5. The valve seat can be selected as a metal hard seal or a soft seal according to the needs of the medium and working conditions. The gate adopts surface chrome plating or ion nitriding treatment, making the gate more wear-resistant and the sealing surface has a longer service life; Soft sealing options include PTFE valve seats, reinforced PTFE valve seats, EPDM or NBR, with good sealing performance and corrosion resistance.

6. Wide range of media adaptability: good sealing performance and strong economic practicality, with manual, pneumatic, and electric operation options, making the practical range very wide.
Commonly used in the papermaking industry, it is suitable for controlling the use of granular and powdery media in equipment such as high concentration slag eliminators, heavy material separators, and hydraulic pulp crushers.
