WZD108 Top Guide Force Shape Regulating Shutoff Valve

WZD108 Top Guide Force Shape Regulating Shutoff Valve

WZD108 pneumatic knife-shaped regulating cut-off valve is composed of pneumatic plug type actuator and knife gate. The valve is compact in design, occupies less space, light weight, easy to install, wear-resistant and anti-blocking measures are perfect, more convenient for installation, long service life, and large flow coefficient. And the unique thin valve body and knife-shaped cut single valve plate structure, making it particularly suitable for dealing with a variety of clean, dirty, sticky table body, especially containing impurities, particles and fiber of the paddle liquid, and with solid powder gas material. Therefore, this product can be widely used in the process control of chemical fiber, papermaking, tap water, sewage treatment, chemical industry, electric power, iron and steel and other industrial sectors to throttle, switch regulation, throttle regulation and so on.

Product overview

WZD108 pneumatic knife-shaped regulating cut-off valve is composed of pneumatic plug type actuator and knife gate. The valve is compact in design, occupies less space, light weight, easy to install, wear-resistant and anti-blocking measures are perfect, more convenient for installation, long service life, and large flow coefficient. And the unique thin valve body and knife-shaped cut single valve plate structure, making it particularly suitable for dealing with a variety of clean, dirty, viscous liquid, especially containing impurities, particles and fiber of the paddle liquid, and with solid powder gas material. Therefore, this product can be widely used in the process control of chemical fiber, papermaking, tap water, sewage treatment, chemical industry, electric power, iron and steel and other industrial sectors to throttle, switch regulation, throttle regulation and so on.
