Z641 series pneumatic wedge gate valve with manual is a pneumatic actuator (double cylinder, and with a shock-absorbing mechanism) and manual and Protection Agency (manual and pneumatic self-locking - Manual conversion device) Low stand clear shot valve. The valve cylinder structure due to the use of double quotes Z641F pneumatic valve, which compared with the single cylinder pneumatic valve, the lifting force increases doubled. Valve Co., Ltd. Shandong Everbright valve manufacturer specializing in the production, welcome new and old customers to order our products! Department is equipped with a pneumatic cylinder head - manual conversion devices. Converting the handle clockwise to mention "pneumatic" positioning hole location, the valve is pneumatically operated state; on the contrary, it is converted to mention the handle counterclockwise to the "manual" is scheduled for hole positioning, valve can be manually operated. Change the direction opposite the handle with a bevel gear. Valve operation manual hand wheel rotation and manual valves, like the ordinary, that turned off clockwise, counterclockwise into the open. With bevel gears in reverse. Valve Co., Ltd. Shandong Everbright produce such a wide range of application types of valves, pneumatic valve Z641F reliable vendors, no internal leakage, leakage phenomenon Z641F pneumatic valve manufacturers, frequent switching is not stuck, rusted, the vast chemical plant , thermal power plants, steel mills, printing and dyeing, food plants the best choice. External corrosion valve pneumatic valve (including variable speed transmission box) inside and outside, at first, blasting sand blasting, non-toxic epoxy powder electrostatic spraying sought, thickness of 0.3mm or more. Large electrostatic spraying toxic epoxy resin valve difficulty should brush, spray similar to non-toxic epoxy paint. And various parts of the body inside the valve plate calls for a comprehensive anti-corrosion, on the one hand immersed in water will not rust, does not produce galvanic corrosion between the two metals; two aspects of smooth surface to reduce drag through the water. 6.3 valve body paint anti-corrosion epoxy resin or health requirements, should detect the appropriate authority of the agency report. Chemical and physical properties should meet the relevant requirements. Z641F pneumatic valve manufacturers | Everbright Valve | Valve Co., Ltd. Shandong Everbright provided by the valve.
