Product Overview:

LXHQ gate valve is a kind of switch valve commonly used in fluid pipeline system. It realizes the complete opening or closing of the medium through the vertical lifting of the gate plate. It has the characteristics of small flow resistance, stable opening and closing, compact structure and so on. It is widely used in liquid, gas or steam pipelines in petroleum, chemical industry, electric power, metallurgy, papermaking, water supply, drainage and other industries. It is suitable for cutting off media and is not recommended for flow regulation.

Product features:

Wedge-shaped or parallel gate structure, reliable sealing and long service life

Channel straight-through structure, small flow resistance, not easy to scale or cause pressure loss

Optional soft seal or metal seal, suitable for different media and temperature requirements

It is easy to open and close, and can be equipped with hand wheel, electric, pneumatic, hydraulic and other driving modes.

Optional rising stem structure (stem lifting visible) or non-rising stem structure (compact and space-saving)

Can realize bidirectional sealing, and the installation direction is not limited

Sturdy construction, easy maintenance, suitable for frequent operation and long-term use
