气动刀型闸阀产品概述
气动刀型闸阀，又称刀闸阀或刀型浆闸阀。其应用范围非常广泛，从矿山、电厂的选煤、排矸、排渣，到城市的污水处理；从水泥、造纸厂的浆液输送，到食品、卫生、医药等专业管道。超薄设计的气动刀型闸阀以其体积小、重量轻、阻流小、不积渣，易安装，易拆卸的优点解决了普通闸阀、平板闸阀、球阀、截止阀、调节阀、蝶阀等阀门的阻流大，占空间，易积渣，不易安装和维修等疑难问题。因而大量的通用切断类阀和调节型阀门被气动刀型闸阀取代。
产品概述
气动刀型闸阀通过配用电磁阀、接近开关等附件可以完成开、关两位置的动作控制和信号输出，也可以完成连续动作的自动控制。用户可根据实际需要进行选择。广泛应用于化工、煤碳、制糖、污水、造纸等领域，是一种理想的密封阀门。特别适合于造纸行业在管道上作调节和节流使用。

Knife Gate Valve Product Introduction
Type knife gate valve, also known as the knife gate valve or knife gate valve type pulp. Its application scope is very broad, from coal mines, power plants, slag discharge, discharging the gangue, the city sewage treatment; From the cement slurry transportation, paper mills, to food, health, medicine and other professional pipeline. Ultra-thin design type knife gate valve with its small volume, light weight, small flow resistance, no slag, easy to install, easy to remove completely solve the advantages of the common gate valve, flat gate valve, ball valve, globe valve, regulating valve, butterfly valve, choke valve, occupy a space, easy slag deposition, not easy to install and maintenance problems. So a lot of general cut off valve and external regulation valve replaced by type knife gate valve.
Product Introduction
Manual pneumatic switch knife gate valve through with solenoid valve, close to switch, etc, can complete the action of two position control and signal output, also can complete automatic control of continuous motion. User can choose according to actual needs. Widely used in chemical industry, coal, sugar, sewage, paper and other fields, is an ideal sealing valve. Particularly suitable for papermaking industry used on the pipeline to adjust and throttling.
