Pneumatic thin gate valve

key word:Heat exchange element


Product description

1. Introduction

 

1.1. Purpose

The pneumatic thin gate valve is mainly used for regulating the flow of ash and slag in the dry ash system of thermal power plant, as well as the opening and closing of wear and corrosion dust media in mines and cement plants.

1.2. Model meaning

KRZ71-**

KRZ71 abbreviation of pneumatic thin gate valve

** -------- inlet and outlet diameter (mm)

1.3. Structural features

1.3.1. The main body of pneumatic thin gate valve is composed of cast steel, 304 stainless steel and graphite sealing ring.

1.3.2. It has the advantages of good sealing performance, high temperature resistance, high pressure resistance, flexible opening and closing, less ash jamming and dust accumulation, long service life, etc.
