slide gate damper

Durable Square / Round Manual Slide Gate Dampers Simple Compact Structure

Product description

Slide Gate dampers are available in round, square, and rectangular configurations or in any combination of the three. Slide Gates are designed strictly for on/off service. They are used primarily as shut off devices for material handling systems such as hopper shut-off valves. Besides their use in hoppers, there are a number of different applications where this type of damper can be utilized.

Slide Gate dampers are available in sizes from 4″ to 60″. Carbon steel is standard, but any weldable alloy can be provided. All Slide Gates have enclosed bonnets, either welded or removable. The enclosed bonnets prevent leakage to the outside atmosphere. The end bonnet on all gates is removable to allow the blade and shaft to be serviced or removed without disassembling the gate from the duct work.

Features

Simple and compact structure and reasonable design

Reliable sealing, light and flexible operation

Small size, smooth passage, low resistance, easy to install and remove

Manual screw gate valve can be installed horizontally or vertically, anti-wear and automatic compensation function, long life

Application

Widely used in metallurgy, mining, building materials, food, manual spiral gate diameter and UN-loader feed port matching; there are two kinds of square and round.

The advantage of this valve is that there is no groove in the valve body, and the medium does not block and block, and it has full-diameter flow characteristics, which is suitable for use in the pipeline of powder and granular media.

The plug door seal structure can be divided into soft seal and hard seal structure. With features such as good workmanship and compact structure, the sealed valve seat is designed as a movable structure and has the functions of anti-wear and automatic compensation, and thus has a longer life. During the closing and opening process of the inserting plate door, the valve seat and the gate plate are always in close contact with each other, so that the valve opening and closing force is stable and has the characteristics of cutting off the medium.

Configure the hand wheel to operate the hand wheel directly to open and close the valve.
