Bronze globe valves are valves with a shutoff valve (disc) moving along the center line of the seat.Depending on this movement of the disc, the variation of the seat orifice is proportional to the disc travel.Due to the relatively short stem opening or closing stroke of this type of valve, and the very reliable cutting function, and the seat port c1
Internal thread gate valve, also known as closure door, is the most widely used one of the valves, belongs to the forced sealing valve, its closure principle is, depending on the pressure of the valve bar, the disc sealing face and seat sealing face tight fit, to prevent the flow of media.It is divided into several categories in different ways.The 1
Internal screw swing check valves refer to opening and closing parts by the flow of media and force to open or close, in order to prevent the media backflow of the valve.
X43W|X43T type plug valve is suitable for opening and closing of water, oil, gas and other medium pipelines with nominal pressure of 0.6-1.0mpa and temperature ≤100℃
Plug valves are shutoff or plunger shaped rotary valves that open or close a valve by rotating 90 degrees so that the port on the plug is identical to or separate from the port on the body.
The purpose of three-way all-copper plug valve is to be installed in the pipeline mainly for cutting, distributing and changing the direction of medium flow.
The opening and closing part of the insulation plug valve is a perforated cylinder that rotates perpendicular to the axis of the passage to achieve the purpose of opening and closing the passage.
Oil-sealed plug valve is suitable for cutting off or connecting the pipeline medium under nominal pressure PN10, working temperature -29 ~ 100℃ in urban construction, chemical industry, metallurgy, petroleum, pharmaceutical industry, food, beverage, environmental protection industry and other working conditions.
Asphalt special valve (also known as plug valve) belongs to the valve, its opening and closing parts (conical plug or ball) around its own center line rotation plug valve is used with the plug with a through hole as the opening and closing parts, through the rotation of the plug body and valve stem to achieve the opening and closing action of the v1
The plug valve, the opening and closing part (conical plug or ball) rotates around its center line. The plug valve USES the plug body with a through hole as the opening and closing part, and realizes the opening and closing action through the rotation of the plug body and the valve stem.
Multifunctional connection gate valve, can be used, installed and replaced in seamless pipe, welded pipe, ductile pipe, cast iron pipe (PVC,PPR,PE pipe, steel plastic pipe), directly reduce flange piece, telescopic device, no need for electric welding butt.
Check valve can regulate the opening and closing speed. When the pump starts or stops running, it can be adjusted to the best opening or closing speed with the on-site adjustment.It is suitable for mining enterprises and high-rise buildings to reduce water hammer and water hammer in direct water supply and drainage system by water pump, so as to ac1
The 500X relief/hold valve is mainly used in fire fighting or other water supply systems to prevent system overpressure or to maintain pressure in fire fighting water supply systems.
400X flow control valve is a kind of valve used to allocate the direction of water supply in parallel water supply system for fire protection and domestic use.
Micro resistance slow closing check valve is a kind of valve.It can be used in the drainpipe line of clean water, sewage and seawater, which can not only prevent the backflow of the medium, but also effectively limit the destructive water hammer and ensure the safety of the pipeline.
