Tonglu Yongxin Valve Co.,Ltd. was founded in 1994, is one of the largest manufacturers in the production of valve,from Tonglu,China. Since 20 years' hard work, probity, and innovation "attention to detail, careful to do everything, has continued to move" to build the first national manufacturer of valve "and make unremitting efforts. Due to our scientific management and Seiko secret agents, as well as "to all customers, all services to the customer" philosophy respected, got the trust of new and old customers.
Knife gate valve, also known as knife gate valve or knife slurry valve, was introduced into China in the 1980s. It has a wide range of applications, from coal preparation, gangue discharge, slag discharge in mines and power plants, to sewage treatment in cities, form slurry transportation in cement and paper mills to professional pipelines such as food, sanitation and medicine.
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.
A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
SPECIFICATIONS: DESIGN AND MANUFACTURE (FULL PORT), FACE TO FACE:DIN3202 15~100 (SerIes F4)125 above(SerIes F5), FLANGE:DIN 2501/DIN2533, PRESSURE TEST:ISO5208 or API598, FLANGE FACINGS AVAILABLE ON REQUEST
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.
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 internal thread gate valve has the characteristics of simple structure, good sealing life, large fluid resistance and poor regulating performance
Main materials of Z15W bronze buckle gate valve are tin bronze C83600, aluminum bronze C95800 and nickel aluminum bronze C95500, etc. The packing and seat seal are made of polytetrafluoroethylene and fluororubber, and the manufacturing standard of internal thread is G thread, BSP thread and NPT thread.Suitable medium: suitable for fresh water, seawater, fuel oil and steam with T ≤120℃.
Sporal gate is used for top, bottom and import and export of building materials, metallurgy, mining, elextric power, chemical industry, glass, light industry, grain and other industries.
Dark plate knife gate valve with cover, also known as gas special valve, is mainly used in gas and sewage gas or liquid pipelines.
Desulfurization and Denitrification Dark Plate Knife Gate Valve with Cover is mainly used in gas and sewage gas or liquid pipelines.
Dark rod knife gate valve is installde by valve stem. There is no lifting action when the valve stem is opened and closed, which saves installation space. Manual knife gate valve can only be fully opened and closed, can not be adjusted and throttled.

Fluorine-lined gate valves are a type of valve.The opening and closing part of the fluorine lined gate valve is the gate, whose motion direction is perpendicular to the fluid direction. The gate valve can only be fully opened and closed, and cannot be adjusted or throttled.
The opening and closing part of the hard sealed gate valve is the gate plate, whose motion direction is perpendicular to the fluid direction. The gate valve can only be fully opened and closed without adjustment or throttling.
Gate Valve opens shuts is the damper plate, the damper plate heading and the fluid direction is vertical, the gate valve only can do all starts with the entire pass, cannot make the adjustment and the throttle. The damper plate has two packing surfaces, but the most commonly used pattern gate valve two packing surfaces form, the wedge-shaped angle wedge-shaped along with the valve parameter different, usually is 50, medium temperature not Gao Shiwei 2°52'.The wedge type gate valve damper plate may make a whole, the named rigid damper plate; Also may make can produce the micro distortion damper plate, improves its technology capability, the atonement packing surface angle the deviation which produces in the processing process, this kind of damper plate named elastic damper plate.The stainless steel gate valve material quality divides into 304 stainless steel gate valves, 316 stainless steel gate valves, 321 stainless steel gate valves.Expressed the method is: Z41H-16P.
