Fluorine valve, Z41F46 
 Valve is one of the most open and close valves with the see of using both sides of the face seal wedge gate to connect or disconnect the piping in the media, wedge gate valve on the pipe does not allow micro-cutting device for use , so as to avoid erosion and high-speed flow of medium to accelerate the sealing surface damage. FEP (F46), PCTFE (F3) fluorine valve applied in -50 ℃ ~ 150 ℃ various concentrations of aqua regia strong oxidant, FEP is also applicable to various concentrations of alkali organic solvents and other corrosive gases, liquid media pipeline use. 
 First, the valve characteristics 
 1 valve body and a round body with flat two shapes: GB valves using a round body, ANSI Class Valves DN ≤ 300Lb pounds using flat body, DN ≥ 400Lb using a round body, valve, gate valve cover of the cavity and plate, the outer surface of stem and other parts in contact directly with the media, all were lining FEP (F46) and other fluorine plastics; 
 2. Sealing of FPF (F46) / FEP (F46) or other material combinations, the friction coefficient is small, opening and closing torque is low; 
 3 filler using PTFE (F4) Standard packing, sealing performance, easy maintenance and replacement; 
 4. With flexible gate, to compensate for gate valve seat sealing surface and sealing surface between the wedge angle deviation, the degree of matching is good, good sealing effect; 
 5 media from both sides in any direction through the valve, the direction for media role may change the pipeline lifting device. 
 Second, the basic model 
 Z41F3 type, Z41F46 type and Z40F3, Z40F46 type. 
 Third, the design specifications 
 Follow the standard GB 12234/API6000 
 Fourth, the drive 
 Manual, electric, under gear, bevel gear.
