Saigao Gate valves. Gate valves are primarily designed to start or stop flow, and when a straight-line flow of fluid and minimum flow restriction are needed. ... The disk of a Gate valve is completely removed when the valve is fully open; the disk is fully drawn up into the valve Bonnet. Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance.The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. Depending on the construction, a partially open gate can vibrate from the fluid flow. Gate valves are mostly used with larger pipe diameters (from 2" to the largest pipelines) since they are less complex to construct than other types of valves in large sizes. At high pressures, friction can become a problem. As the gate is pushed against its guiding rail by the pressure of the medium, it becomes harder to operate the valve. Large gate valves are sometimes fitted with a bypass controlled by a smaller valve to be able to reduce the pressure before operating the gate valve itself. Gate valves without an extra sealing ring on the gate or the seat are used in applications where minor leaking of the valve is not an issue, such as heating circuits or sewer pipes.

Purposes Screw gate valve is a main control equipment on flow or feed amount of powder materials,crystal grain materials,particle materials and tiny mass materials,and it is widely used in controlling flow amount variation or quick cut-off in metallurgy. Mining, constructional materials, foodstuff, chemical industry and so on. Features Simple structure, flexible in operation, little weight,no locking,specially suitable for feeding and flowing amount regulation of various solid materials and mass, conglomerated materials with diameters around 50mm, installation is not restricted by angles, easy to operate, and sizes are adjustable at any time.
Wedge gate valve adpot wedge disc as closing part ,it is widely use in water, steam, oil, gas and other corrosive medium. The gate valve can also be used in the environment with high temperature and high pressure. Features 1.Manufactured with straight-through channel, the energy loss is less than that of the S type channel, the flow direction of the medium is not changed when passing through the gate valve. 2.The wedge structure of the valve plate makes for large loading coefficient of the sealing. Safe and reliable ,so this wedge gate valve can be used under high pressure. 3.The high precision of the valve stem realizes the tight integration with stuffing .So, medium leakage can be avoided.
