Gate valve series

A gate valve is an opening and closing component, and its movement direction is perpendicular to the fluid direction. A gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

Globe valve series

Globe valve, also known as shut-off valve, belongs to the forced sealing type valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak.

Ball valve series

Ball valve, the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control.

Check valve series

A check valve refers to a type of valve whose opening and closing components are circular valve discs that act by their own weight and medium pressure to block medium backflow. It belongs to the category of automatic valves, also known as check valves, one-way valves, return valves or isolation valves. The valve disc movement can be divided into lifting and rotating types.

Filter series

A filter is an indispensable device on the pipeline for conveying media, usually installed at the inlet of pressure reducing valves, relief valves, constant water level valves, and other equipment such as square filters. The filter consists of a cylinder, a stainless steel filter screen, a drainage part, a transmission device, and an electrical control part, making it easy to use and maintain.

Butterfly valve series

Butterfly valve, also known as flap valve, is a type of regulating valve with a simple structure that can be used for on/off control of low-pressure pipeline media. Butterfly valve refers to a valve whose closing element (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve opening and closing.
