Cast Iron knife gate valve for water treatment

Knife Gate Valve Model:

The knife gate valve is truly a high performance knife gate valve design. This valve provides zero leakage

bi-directional shut-off, has mechanically retained seal, has a compact non-rising stem design, and can be

repacked in service under full pressure. The chest and seating areas of the valve are self-cleaning. The

reduced chest area, minimal gate arc, and contoured flushing corners in the body prevent jamming by

eliminating material build-up in the chest, body and seating area. The gate seals against a combination

metal and resilient seat and is guided for the full stroke length of the valve. The top “transverse” seal is repackable while in service under full pressure. The valve is tested and rated for zero leakage (liquid or

gas) downstream and to atmosphere.

Compare these unique features:

1. Transverse seal eliminates stuffing box and permits repacking under full pressure and without system

shut-down.

2. Mechanically retained resilient seat provides dual metal-to-metal and resilient seating for zero leakage

bi-directional shut-off from absolute vacuum to rated valve pressure.

3. Bi-directional design. Gate is guided and supported for smooth operation throughout the entire stroke

with flow in both directions.

4. Contoured interior body promotes flushing action to prevent build-up of process media in the seating

area.

5. Solid steel or stailess steel topworks provide maximum strength to prevent damage due to operator

abuse or vibrating conditions.

6. Non-rising stem design saves space and reduces stem nut repair problems.
