Stainless steel three eccentric hard seal butterfly valve, three eccentric hard seal butterfly valve, hard seal butterfly valve

Stainless steel three eccentric hard seal butterfly valve, is corrosion resistant butterfly valve, made of corrosion resistant stainless steel. Stainless steel grades: 904L, 254SMo, 1.4529 super stainless steel, 2205, 2507 duplex steel, 317L, SS304, SS316, SS316L stainless steel. Nominal pressure: 1.0MPa-6.4MPa, nominal diameter: DN50-DN2000.

Stainless steel three eccentric hard seal butterfly valve design structure is according to the principle of three-dimensional eccentric design, 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 flexible and radial compression, sealing more reliable, and not easy to close too much.

Pneumatic actuator

Our company butterfly valve for users to provide double-acting pneumatic, as well as single-acting pneumatic, cylinder cylinder using high-quality alloy aluminum extrusion molding, die-cast aluminum cylinder head, cylinder cylinder bottom installation surface (valve connection) in line with 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 three eccentric hard seal butterfly valve has good corrosion resistance, high temperature resistance, wear resistance and sealing performance, so it is widely used in many fields. The following is its main application scope: metallurgy, electric power, petroleum, chemical, air, gas, combustible gas and water supply and drainage and other corrosive media pipeline. Urban heating system 3. Cooling water systems for thermal power stations. Water, steam, oil, air, gas and other media
