Custom processing special brand of double Model D643W-1 Material Stainless Steel Connection Type inclined plate flange structure Xiamen For media Water Pressure environment Pressure Operating temperature Room temperature Standard GB Flow direction Unidirectional Drive Pneumatic D643W manual dual gas valve Product Description: Features : dust and gas valve designed according to the nature and characteristics of dust and gas, suitable for dusty gas, clean coal, gas and other flue gas pipe road dust control adjustment purposes do. Industry: metallurgy, chemicals, machinery, cement, electricity and other sectors of gas pipes and road protection, dust removal facilities systems. Product has more advantages than other stores: operating torque, opening and closing speed, long service life, the valve sealing parts made of high strength materials, with good performance characteristics of high abrasion and erosion detection method: Conforms Q / SF.JO1 -91 Standard main performance specifications Nominal MPA 0.1 MPA 0.11 Sealing test pressure strength test pressure MPA 0.15 applicable rate <20 trial temperature <350 leak rate of 0.3% Note: The leakage rate refers to the butterfly plate and valve leakage between the area and the maximum flow area of than the main body parts and materials Part name plate board material ductile cast iron, carbon steel, Carbon Steel Mill manual dual gas valve D643W Product structural features: D743W-1 type hydraulic type dust and gas valve utilizing hydraulic actuator driven by a mechanical actuator open and close the disc to complete the action. Disc working position can be displayed by the limit switch signal. Throttle valve opening and closing speed can be adjusted. The valve can be remotely controlled individually, you can also centralized control. The signals can also be programmed into the computer control. The valve can be used in a non-normal wrench for manual operation. Please refer to this valve is installed in a horizontal pipe installation when determining the direction shown in Fig prevent dust accumulation increases the valve open resistance. Structural features: D643W-1-type pneumatic dust and gas valve pneumatic devices through the use of a mechanical actuator drive to achieve open and close the butterfly newspaper. Disc working position can be displayed by the limit switch signal. Throttle valve opening and closing speed can be adjusted. The valve can be a single remote control, you can also remote centralized control, but also can be a signal input computer program control. The valve in the non-normal conditions, can also be operated manually wrench. Please refer to this valve is installed in a horizontal pipe installation when determining the direction shown in Fig. In order to prevent dust accumulation increases the valve open resistance.
