Large Diameter Butterfly Valve

Production Description

● Light weight, easy to install and debug. The valve plate adopts a streamlined design, and the large-diameter butterfly valve adopts a truss structure. The product has good rigidity, large overflow and small flow resistance.
● Reliable sealing. The second eccentric design is reasonable. The higher the pressure, the tighter the seal. The disc sealing ring has a certain elastic compensation ability and is not sensitive to local wear.
● Appropriate hardness, good elasticity, anti-aging and strong tear resistance. The sealing ring of the soft sealing butterfly valve is made of high-quality oil-resistant nitrile rubber and EPDM rubber.
● Reliability of the shaft seal. There is a window at the packing, which can be tightened or replaced online without disassembling the valve.
● High carrying capacity. Oil-free self-lubricating bearings are used, with low friction coefficient.
● The end of the valve shaft is equipped with a thrust bearing, no matter whether it is horizontal or vertical, the butterfly plate will not move, and the axial seal is reliable.
● The unique design of the three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve.
● An elastic seal is produced by torque.
● The clever wedge-shaped design enables the valve to have the automatic sealing function of closing and tightening, with compensation and zero leakage between the sealing surfaces.
● Small size, light weight, light operation and easy installation. Easy to disassemble and maintain, and can be installed in any position.
● Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
● The material of the replacement parts can be applied to various media, and can be lined with anti-corrosion (lining with F46, GXPP, PO, etc.).
Diversification of continuous structures: wafer, flange, butt welding.

Application Area

1. The butterfly valves of our company are widely used in water supply and drainage and power generation systems such as municipal water pipe network, cooling water system, hydroelectric power generation system, sewage treatment plant, water diversion project, chemical industry, smelting, etc. It is suitable for raw water, clean water, corrosive gas, Introduction to liquids and multiphase fluids, with functions of heaven, cut-off or non-return.
2. The butterfly valve with double eccentric or triple eccentric structure is suitable for one-way sealing. Generally, it should be installed in the marked direction; if the sealing condition is two-way, please indicate it in the order contract, or use the centerline butterfly valve instead.
3. The company can according to the contract requirements and user conditions. Supplied with hard sealing butterfly valve. Soft-sealed butterfly valve and midline butterfly valve are available in manual, electric, pneumatic, hydraulic control and other operation modes to meet the individual needs of the transfer to the greatest extent.
