Ball type ON-Off valve, globe control valve, ball control valve, pneumatic control valve, electric control valve;
A butterfly control valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.
A butterfly valve is from a family of valves called quarter-turn valves.
ZSHWB Series of Double Eccentric Butterfly Valve(High performance butterfly valve), both valve disc and sealing ring are designed in special eccentric structure, with characteristics of impact structure, good shut-off performance, repair and replace conveniently and long operation life, so it has both regulating and shut-off functions, which could be widely used to cut off and regulate the processing fluids, such as metallurgy, oil, chemical engineering, electric power, natural gas.

Water spraying truck (also called water sprinkler truck, mobile Water Truck, watering truck, Water Bowser, water truck tanker, water carrying truck, water tank for truck, water distribution truck) is used to transport and supply water, whatever industrial or agriculture water, widely used in construction engineering, farm irrigation, draught relief, etc.
With non-toxic treatment inside tank or tank made of stainless steel, the water tank truck can be suitable for transporting drinking water, called as potable water tanker, drinking water tanker, stainless steel water tanker, agua potavel, safe to human body.
Water tanker can also be equipped with special sprayers to achieve front flush, rear sprinkle, side spray, to sprinkle and clean the roads, streeets for environmental sanitation and protection, called as water sprinkler, water spray truck.
With rear working platform and high cannon, the Water lorry can also be used to water the plants, even high trees in virescence, called as watering truck.
Water bowser can be also equipped with pesticide spraying machine, to be used to spray pesticide in agriculture pest control field.
