Stainless steel pneumatic three eccentric butterfly valve, pneumatic three eccentric butterfly valve, butterfly valve

Stainless steel pneumatic three eccentric butterfly valve, controlled by pneumatic actuator, flange connection or clamp connection, nominal pressure: 1.0mp-6.4mpa, nominal diameter: DN50-DN2000. Stainless steel pneumatic three eccentric butterfly valve using corrosion resistant stainless steel, mainly used in a variety of corrosive media. Material: 904L, 254SMo, 1.4529 super stainless steel, 2205, 2507 duplex steel, 317L, SS304, SS316, SS316L stainless steel.

The design structure of the three eccentric butterfly valve is designed according to the principle of three-dimensional eccentricity, the butterfly plate is provided with multilayer soft and hard material superposition of the sealing ring, the valve plate sealing ring and the valve seat contact surface is oblique taper, the contact Angle produces a slight "wedge effect", so that the sealing ring occurs soft and radial compression, the sealing is more reliable, and not easy to close too much.

Standard for pneumatic actuators

The pneumatic actuator has double-acting pneumatic, single-acting pneumatic, the cylinder body is extrudated by high-quality alloy aluminum, die-cast aluminum cylinder head, the bottom mounting surface of the cylinder body (valve connection) conforms to ISO5211 and DIN3337 standards.

Pneumatic accessories: locator, solenoid valve, limit switch, filter decompression device, handwheel, retention valve, quick discharge valve, etc.

Pneumatic installation standard:

1, quick installation, cylinder bottom mounting surface (valve connection) in line with ISO5211 and DIN3337 standards, compared with other manufacturers cylinder bottom four more connecting thread hole adapter plate. If the ISO hole at the bottom of the cylinder and the flange hole of the valve (such as American standard or other standards) cannot be matched, the connection can be properly completed by using the company's switchboard. A variety of adapters are available to fit a variety of stem sizes for installation.

2. The top mounting surface conforms to the VDI/VDE3845 standard, which is convenient to install the locator and limit switch box and other accessories.

3, stainless steel 304 adjustable positioning bolt to achieve output shaft +/-5 degree rotation accuracy adjustment.

4. The side inlet interface is connected to the VDI/VDE3845 NAMUR standard, and the solenoid valve can be easily installed.

Stainless steel pneumatic three eccentric butterfly valve applications include:

Petroleum, chemical industry, metallurgy, electric power, food, medicine, water supply and drainage, gas transportation and other industries: used for switching off or regulating medium flow parameters.

All kinds of corrosive medium environment: such as seawater, wastewater, slurry, acid-base solution, high concentration chloride ion water, gas, etc

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.
