Pneumatic valve is an actuator that uses compressed air to drive and operate the valve. Its opening and closing speed is relatively fast. It is often used for quick two-position cut-off, and can also be used to adjust flow. Because it mainly relies on air source to perform operation, In flammable and explosive situations, it has high practicability and can be used to control gas, liquid, oil, and …

Swing check valves can be installed horizontally or vertically. The disc of swing check valve rotates around the rotating shaft, and its fluid resistance is generally smaller than that of lift check valve. It is suitable for occasions with larger diameters, and the installation position is not limited. It is usually installed in horizontal pipelines. It is suitable for use with for larger diameter…

The electric three-way ball valve is composed of an electronic electric actuator and a three-way ball valve. It is a rotary cut-off regulating valve with the advantages of tight closing, compact structure, light weight and convenient maintenance. It is widely used in pipeline automation control of corrosive media such as gas, liquid, steam and oil.…

The angle control valve has a simple flow path and low resistance, and is generally suitable for forward use (installation). However, in the case of high pressure drop, it is recommended to use the angle control valve in reverse, to improve the unbalanced force and reduce the damage to the valve core, and it is also conducive to the flow of the medium and avoids coking and clogging of the control …

The elastic soft sealing gate valve and the hard sealing gate valve are for the sealing material of the valve seat. The hard sealing is precision machined with the valve seat material to ensure the matching accuracy with the valve core (ball), generally stainless steel and copper. Soft seal means that the sealing material embedded on the valve seat is a non-metallic material. Because the soft seal…

Large-diameter flanges commonly include flat welding flanges and butt welding flanges. Threaded flanges do not have large diameters. In the actual production and sales, the proportion of flat welding products is still much. Flat-welded large-diameter flanges and butt-welded large-diameter flanges have different structures and ranges of use, and can exhibit different features and advantages. Theref…

Y-type filter is an indispensable filter device in the pipeline system for conveying medium. Y-type filter is usually installed at the inlet end of pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to remove impurities in the medium. To protect the normal use of valves and equipment. The Y-type filter has the characteristics of advanced structure, small res…

V-shaped ball valve, also called: V-shaped cut-off valve, V-shaped regulating ball valve; this kind of ball valve is a fixed ball valve, and it is also a single-seat sealing ball valve. Its regulating performance is the best among ball valves.…
