Pneumatic Rod Gate Valve is a kind of linear motion on-off valve driven by pneumatic actuator,also named pneumatic slide gate valve.It is specially designed for cutting off and discharging bulk solid materials,powder,granules and ash slag in silos,hoppers,conveyors and dust removal systems.

Working Principle

The pneumatic actuator drives the valve rod to push the gate plate to move linearly forward and backward.

When opening:the gate plate retracts,the material passage is fully opened for free flow.

When closing:the gate plate slides into the sealing position to realize complete cut-off and dust-tight sealing.

It adopts straight rod transmission structure,stable running,no jamming,suitable for frequent opening and closing.

Main Structure

Pneumatic actuator:double acting cylinder,stable driving force

Valve rod&gate plate:integrated design,wear-resistant and high strength

Valve body:carbon steel/stainless steel,thickened plate structure

Sealing part:rubber or PTFE sealing strip,good airtight performance

Installation interface:square,rectangular or round flange,easy to connect with silo and chute

Key Features

Simple rod drive structure,stable operation and low failure rate

Good wear resistance,suitable for powder,particle,ash and bulk materials

Dust-tight sealing effect,no material leakage,environmental protection and dust prevention

Pneumatic automatic control,can match solenoid valve,limit switch and PLC remote control
