Product Description

Introduction:

Knife gate valve, also known as knife gate valve or knife slurry valve, has a wide range of applications, from coal preparation, gangue and slag discharge in mines and power plants, to urban sewage treatment; from slurry transportation in cement and paper mills to Professional pipelines for food, sanitation, medicine, etc. The ultra-thin design knife gate valve completely solves the problems of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves, etc. due to its small size, light weight, low flow resistance, no slag accumulation, easy installation and easy disassembly. Problems such as large flow resistance, space occupation, slag accumulation, and difficult installation and maintenance. As a result, a large number of general shut-off valves and regulating valves have been replaced by knife gate valves.

 

Applied medium:

Gold ore powder, tailings, ore sand, slag, coal slime, sand, steel ash, paper pulp, wood pulp, cement slurry, fiber, dust, powder, grain, chemical treatment sewage, slaughterhouse wastewater, urban sewage, Precipitating oil, asphalt, silo export, fruit, grain, beer, beverage, oil, steam, gas transportation, power plant water supply and drainage, slag discharge, etc.

 

Sealing material description :

1. Soft seal (one-way or two-way) temperature resistance ≤280℃; applicable medium is gas, liquid and other gas-liquid medium with strong fluidity and low density. Its advantages: strong sealing performance, not easy to leak inside and outside. Its disadvantages: contact with particles or high-temperature media will cause seal damage.

2. Hard seal (one-way or two-way) temperature resistance ≤1000℃: suitable for a variety of hard media such as solids, dust, particles, etc. Its advantages: strong abrasion resistance, its disadvantages: poor airtightness, unsuitable for application in other and liquid pipelines
