Product Overview

Pneumatic knife gate valve has a wide range of applications, from mining, power plant coal, gangue, slag discharge, to the city's sewage treatment; from cement, paper mills, slurry transportation, to food, health, medicine and other professional pipelines. Ultra-thin design knife gate valve with its small size, light weight, small obstruction of flow, no accumulation of slag, easy to install, easy to dismantle the advantages of a complete solution to the common gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves and other valves of the obstruction of flow, occupying space, easy to accumulate slag, not easy to install and repair and other difficult problems. Therefore, a large number of general cut-off type valves and regulating valves are replaced by knife gate valves.

Structural Features

Pneumatic knife gate valve short structural length, saving materials, can make the pipeline system overall weight reduction, occupies a small space, can support the strength of the pipeline, can reduce the possibility of pipeline vibration, gate selection of austenitic stainless steel, corrosion resistance, can be exempted from sealing leakage caused by corrosion of the gate, the upper sealing filler using flexible PTFE, sealing, lightweight operation, the gate has the function of a gate knife, can gate off the medium in the Sundries.


Pneumatic knife gate valve is a more complex automation control instrument, composed of a variety of pneumatic components and valve body. Mostly used for the requirements of fast cut off or open occasions, double role of the valve to open and close the two-position control, single-action spring reset, in the electrical and gas circuit cut off or failure, the valve automatically open or close. Optional accessories, single or double control solenoid valve (24V, 220V and other voltages for choice, optional explosion-proof solenoid valve), proximity switches, gas source processing triple (including pressure reducing valve, filter, oil mist), electric/gas valve positioner (regulating type).
