Three eccentric all metal seal butterfly valve, all metal seal butterfly valve

Three eccentric full metal sealing butterfly valve, is designed for high temperature and high pressure conditions butterfly valve, using three eccentric structure, full metal sealing ring, not multi-level sealing ring. Model D943Y, D673Y, D363W, material: SS304, SS316, SS317L, 2205, 2507, 904L, 254SMo, 1.4529 stainless steel.

Three eccentric structure

Three eccentric full metal sealing butterfly valve adopts three eccentric structure, so that the butterfly plate in the process of opening and closing, no sliding friction, no clamping between the seat, with the more closed the sealing advantages, eliminate the uneven load between the sealing pair, greatly extend the service life of the valve. When the valve is opened and closed, the sealing surface of the butterfly plate touches or disconnects immediately along the points of the 360 degree circle, which can quickly and accurately realize the opening or closing action.

Three eccentric full metal sealing butterfly valve, metal sealing ring can be surfacing or spray welding a variety of wear and temperature resistant alloy, to achieve high temperature resistance, high pressure resistance, wear resistance, anti-scouring requirements, use in high temperature or low temperature conditions, to maintain the reliability of the seal, Used in electric power, water supply, heating, water treatment, waste gas treatment, seawater desalination, chemical industry, petroleum, metallurgy, electronics, building materials, paper making and other industries.

Fire resistant structure in the real sense

Three eccentric full metal sealing butterfly valve because of the full metal seat and sealing ring sealing structure, adapt to high temperature working conditions, and two-way zero leakage, can realize the real sense of fire function.

Double bevel - surface seal structure

The sealing surface of the all-metal sealing butterfly valve adopts the double bevel - surface sealing structure, which reduces the radial eccentricity, greatly increases the width of the sealing surface, makes the sealing pressure of the valve small, anti-friction, and reduces the operating torque of the valve.

Double stem design with spline connection

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.

Three eccentric full metal sealing butterfly valve, metal sealing ring can be surfacing or spray welding a variety of wear and temperature resistant alloy, to achieve high temperature resistance, high pressure resistance, wear resistance, anti-scouring requirements, use in high temperature or low temperature conditions, to maintain the reliability of the seal, Used in electric power, water supply, heating, water treatment, waste gas treatment, seawater desalination, chemical industry, petroleum, metallurgy, electronics, building materials, paper making and other industries.

Packing of Standard Packing:
