Manual Knife Gate Valve

Manual through type plug valve is a type of valve where the gate and valve seat are always in close contact and sealed. Its principle is that the gate has a circular opening of the same diameter

Performance

¡ð A valve with a gate and seat that are always in close contact and sealed. Its principle is that the gate has a circular opening of the same diameter, and by opening and closing the gate, the circular opening on the gate completely disengages and matches the diameter. The gap between the valve chamber and the gate is small, and the medium will not be retained in the valve chamber as the gate moves.

¡ð The sealed valve seat is designed with a movable structure, which has anti-corrosion and automatic compensation functions, resulting in a longer service life. During the closing, opening, and opening processes, the valve seat moves closely with the gate plate, making the valve opening and closing force stable and having the characteristic of cutting off the medium.

¡ð During installation, there is no angle limitation, making it easy to operate and adjust the scale at any time. This structure completely solves the problem of valves not getting stuck in pipelines when installed horizontally, at any angle, or vertically.


Application

¡ð Manual isolation and maintenance isolation of the coal powder silo discharge port in the power plant

¡ð Manual full diameter cutoff control point for raw material conveying chute in cement plant

¡ð Chemical dust storage tank outlet requires high sealing manual plug valve

¡ð Manual operation of partition device during maintenance of metallurgical pneumatic ash conveying system

¡ð No residue in food and pharmaceutical powder pipelines, manual switch safety control
