Electric full metal hard seal butterfly valve, metal hard seal butterfly valve, electric butterfly valve,

Electric all metal hard seal butterfly valve, belongs to three eccentric butterfly valve, all metal sealing ring, surfacing or spray welding alloy, so that the seal is resistant to high temperature, high pressure, scour resistance, wear resistance. Electric full metal hard seal butterfly valve, flange connection or clamp connection, by electric control, optional intelligent electric, explosion-proof electric, adjustable electric, model D973Y, D943Y, material: 304, 316, 317L, 2205, 2507, 1.4529, 904L stainless steel.

Electric all-metal hard seal butterfly valve sealing ring, in the high temperature or low temperature conditions can be used, the import and export sides of the force is about balanced, the opening moment of the valve is low, the forward and reverse sealing performance is reliable, used in electricity, water supply, heating, water treatment, waste gas treatment, desalination, chemical industry, petroleum, metallurgy, electronics, building materials, paper and other industries.

Electric full metal hard seal butterfly valve is three eccentric double bevel seal structure, so that the butterfly plate in the process of opening and closing, the butterfly plate sealing surface along the 360 degree circumference of the point of instant contact or detachment, no sliding friction, no clamping between the seat, with the more closed the sealing advantages, eliminate the uneven load between the sealing pair, greatly prolong the service life of the valve.

Upper and lower stem design

Valve stem and butterfly plate, valve stem and drive, all adopt splinted connection structure, uniform force, easy disassembly and assembly, reduce the long-term maintenance cost of the product.

Lower valve stem fixed shaft structure, better rigidity, can shorten the valve stem inserted into the butterfly plate connection, so that the channel flow resistance is smaller.

The upper valve stem has no pin to prevent blowout structure. The design structure of the double valve stem solves the problem of inconsistent expansion between the valve stem and the butterfly plate and the valve body caused by thermal expansion.

Anti-lock, dustproof, anti-crystallization

Self-lubricating bushing design, to a greater extent to solve the valve stem lock problem, the upper and lower bearing dustproof structure, add spiral groove anti-crystallization structure.

The dynamic load packing machine with disc spring can automatically compensate the loss of packing and prevent the leakage of medium.

Electric all-metal hard seal butterfly valve sealing ring, in the high temperature or low temperature conditions can be used, the import and export sides of the force is about balanced, the opening moment of the valve is low, the forward and reverse sealing performance is reliable, used in electricity, water supply, heating, water treatment, waste gas treatment, desalination, chemical industry, petroleum, metallurgy, electronics, building materials, paper and other industries.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
