1.Structure of Gate Valve Description：
A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired.

2.Main Features of the Gate Valve：
• Valve body cavity using non-toxic epoxy resin,both inside and outside flashboard completely is coated with rubber
• High manufacturing accuracy
• High strength
• Environmental protection and energy saving

1.What's are the characteristics of gate valve?

The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired.

2.What is the structure?

Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning.

Q:The main question is, what are the functional differences in which case?: The gate (gate valve) is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle gate valve. The direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.Gate valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex

Q:About fire valve is gate valve or butterfly valve problems?: Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.

Q:Function of signal butterfly valve and gate valve: The signal is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate. Signal gate valve is usually horizontal installation.

Q:Soft sealed gate valve and hard sealing gate valve which good?: If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.

Q:What is the standard for ductile iron gate valve set?: Fujian - mark light - valve for you to answer:Whether it is the next shot or dark bar, directly flanged valves can be installed, usually apply eighth copies, if the industrial pipeline is apply sixth copies, sixth copies to apply separate sets of flanges and bolts (bolts independent fee).

Q:Is the gate valve clockwise or closed?: In general, the valve is clockwise to turn off. Some of the clockwise rotation of the valve on the move is open

Q:What is the difference between the copper gate valve and the ordinary material gate valve?!: The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.

Q:Notes on flat gate valves: Use, maintenance, maintenance and precautions1. valve before leaving the factory have made strength and sealing test, the use of all connections should maintain the initial state.2. this series of valve operating handwheel is marked with open and close rotary direction, and the upper part of rod is equipped with open and close height gauge for regulating indication.3. when the valve and pipeline welding, the valve should be opened, appropriate to protect the neck with moisture, minimize heat conduction, to prevent damage to the sealing packing parts.4. when the valve is closed, the lever shall not be used. When the gate is closed to the top, the handwheel shall be turned 1/2 so that the gate is in a floating state.5. in the use of the valve should be regularly to the valve cap injection grease joint into the quantitative grease.6., the valve in use, such as vulnerable parts and leakage, should be replaced in time.7., the valve in the overhaul process, the cavity should be cleaned, the assembly should be added to the transmission parts of grease.8. valve storage during the shutdown, the gate should be in the closed position, long-term storage should be placed in ventilated dry place, regular inspection and maintenance.

Q:Z41T one 10 gate valve and Z44T one, 10 gate valve difference: Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa
