LXHQ Knife gate valve

Product Overview:

LXHQ knife gate valve is a kind of cut-off valve specially designed for media containing particles, slurry, fiber or powder. The valve plate is knife-shaped, which can cut off or scrape off the media. It is suitable for working conditions requiring low pressure, frequent opening and closing, viscous media and easy blockage. With compact structure, convenient opening and closing and small space occupation, it is an ideal cut-off equipment for paper pulp, sewage, coal slime, ore pulp, chemical slurry, grain transportation and other industries.

Product features:

Knife-gate design with shear function for cutting solid or fibrous media

Compact structure, small occupied space, suitable for narrow installation environment

Easy to open and close, suitable for frequent operation

Reliable lower sealing structure to prevent medium deposition or jamming

Two-way seal optional, supports two-way pressure-tight shutoff

Multiple driving modes: manual, pneumatic, electric and hydraulic

The valve body can be provided with a slag outlet, which is convenient for cleaning and maintenance.
