Pneumatic stainless steel ventilation butterfly valve, stainless steel ventilation butterfly valve, pneumatic ventilation butterfly valve

Pneumatic stainless steel ventilation butterfly valve, for a variety of temperatures containing acid and sulfur flue gas and exhaust emissions, valve body and internal parts are corrosion resistant stainless steel materials, 304, 316, 316L, 2520, 310S stainless steel. Model TD641W, diameter DN50-DN3000, pressure PN0.1MPa.

Pneumatic stainless steel ventilation butterfly valve is a midline structure, the valve plate is located in the center of the valve body, the valve body is equipped with a retaining ring, the sealing surface is easy to process, allows a low leakage rate when closed, will not close, the sealing surface clearance value is controlled within 0.2% of the channel area. The dimensional accuracy of the valve body and the butterfly plate seal pair is machined to meet the design requirements.

Pneumatic stainless steel ventilation butterfly valve installation should pay attention to the flow of medium, so that the opening direction of the butterfly plate is consistent with the flow direction of the pipeline medium, which is helpful to the self-cleaning effect of the medium flow rate.

Requirements for pneumatic actuators

The pneumatic actuator cylinder body of our company's pneumatic stainless steel ventilation butterfly valve is extruded from high quality aluminum, die-cast aluminum cylinder head, and the mounting surface at the bottom of the cylinder body (valve connection) conforms to ISO5211 and DIN3337 standards. Pneumatic actuators are divided into single action (spring reset) and double action according to the action form. In case of failure, there are three types of valve positions: valve position closed, valve position open, valve position hold.

Pneumatic actuator can be matched with a variety of accessories, including locator, limit switch, filter and decompression device, solenoid valve, 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, design a plurality of rotary plate connection threaded holes. 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.

Pneumatic stainless steel ventilation butterfly valve is widely used in many industrial fields, specific applications include: petrochemical: for oil refining, petrochemical and other industries medium regulation and flow control. Sewage treatment: used for flow control and medium regulation in municipal sewage treatment plants. Power industry: Flow control for cooling water systems and flgas systems of power plants is the largest application segment in the field of electric power environmental protection, accounting for more than 35% of the market share. Food industry: used for fluid control and regulation in food processing. Pharmaceutical industry: used for fluid control and temperature regulation in pharmaceutical processes. Metallurgical industry: used for blast furnace gas, dust removal and other links. Chemical industry: used for the treatment of corrosive gases. Building materials industry: for cement kiln head kiln tail ventilation dust removal. Mine industry: used for ventilation and dust removal. Environmental protection industry: used for desulfurization and denitrification, pneumatic transportation and other links
