Cast Iron Knife Gate Valve Stainless Disc EPDM/NBR Seat

Product features of electric knife gate valve

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

2. The screw drive adopts a double-device bearing design, which greatly reduces the transmission friction and facilitates the opening and closing of the valve.

3. The sealing seat of the knife gate valve adopts a movable seal, and the O-ring pretension provides pre-loading force to make the sealing seat close to the valve     plate,   minimizing leakage and having an automatic compensation function for the fatigue of the sealing pair during long-term use. , improve the service life of the   valve.

4. Fixed guide claws and bracket-less design are less likely to cause media accumulation and jamming.

5. The valve seat can choose metal hard seal or soft seal according to the needs of the medium and industry and mining: the gate plate adopts surface hard chromium plating or ion priority treatment to make the gate plate more wear-resistant and the sealing surface continues to be enhanced; soft seal valve seat is optional PTFE, NBR, EPDM valve seats have good sealing and corrosion resistance.

6. Equipped with a DZW multi-turn electric actuator or electric-hydraulic actuator with AC380V power supply, the opening and closing of the slurry valve can be controlled.
