Bottom price Air Flow Control Valve - GB Cast Steel Gate Valve With Flange Ends Stainless Steel – Yingzhong

Production Description

● The gate valve has reasonable structural design, reliable sealing, smooth passage and small flow resistance coefficient.
● The gate and valve seat sealing surfaces are made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life.
● Adopt wedge-type elastic gate or rigid wedge-type single gate structure, medium and large diameter rolling bearings, flexible switch, easy opening and closing.
● The valve stem is quenched and tempered and surface nitrided, which has good corrosion resistance, scratch resistance and wear resistance.
● Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
● The valve body has a complete variety of materials, and the packing and gasket can be reasonably selected according to the actual working conditions or user requirements, and can be suitable for various pressure, temperature and medium working conditions.
● The valve has significant advantages such as light switch, reliable sealing, good elastic memory and service life.
● It is more labor-saving when opening and closing. Compared with the globe valve, because whether it is open or closed, the direction of movement of the gate is perpendicular to the flow direction of the medium.
● The height is large and the opening and closing time is long. The opening and closing stroke of the gate is large, and the lowering is carried out by the screw.
● The medium can flow in any direction on both sides and is easy to install. The gate valve channel is symmetrical on both sides.
● The structural length (the distance between the two connecting end faces of the shell) is small.
● The shape is simple, the length of the structure is short, the manufacturing process is good, and the scope of application is wide.
● The structure is compact, the valve rigidity is good, the channel is smooth, the flow resistance is small, the sealing surface is made of stainless steel and hard alloy, the service life is long, and the PTFE packing is used. The sealing is reliable. The operation is light and flexible.

Application Area

This valve is suitable for various industries such as petroleum, chemical, electric power, steel, mining, heating, etc.
