First, Z41F46 lining fluoride valve Product Description:
 Z41F46 lining fluoride valve products is a kind of the most visible opening and closing valve, the use of both sides sealed wedge-shaped gate to connect or cut off the pipeline medium, wedge gate valve does not allow trace Opened in the pipeline for throttling device, so as to avoid high-speed flow of media erosion and accelerate the sealing surface damage. FEP (F46) and PCTFE (F3) Lined Fluoride Gate Valves are applicable to various concentrations of aqua regia, acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants and FEP lined fluorine valve at -20 ℃ ~ 150 ℃ Also suitable for a variety of concentrations of strong alkali organic solvents and other corrosive gases, liquid media used on the pipeline.

Z41F46 lining fluorine valve used for sealing FEP or other material combinations, the friction coefficient is small, low opening and closing torque; PTFE filler material standard, sealing performance, easy maintenance and replacement; with flexible gate to compensate for gate seal And seat sealing surface wedge angle deviation, good agreement, sealing effect is ideal.
 

Second, Z41F46 lining fluoride valve Application:
 Z41F3, Z41F46 lining fluoride valve for a variety of concentrations of -50 ℃ ~ 150 ℃ aqua regia, sulfur, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants, FEP Also suitable for a variety of concentrations of strong alkali organic solvents and other corrosive gases, liquid media used on the pipeline.

Valve body has two kinds of flat body and round body: GB GB valve adopts round body, ANSI grade ANSI standard valve DN≤300Lb adopts flat body, DN≥400Lb adopts round body.


Third, Z41F46 lining fluoride valve structure features:
 1, the valve body, the valve cover and the gate, the outer surface of the stem and other parts in direct contact with the media, all name lining FEP (F46) and other fluoroplastics; 
 2, It has low friction coefficient and low opening and closing torque for FPF (F46) / FEP (F46) or other material combination. 
 3. The packing is made of PTFE (F4) standard packing with good sealing performance and easy maintenance. 
 4, Board can compensate for the wedge angle deviation between the sealing surface of the gate plate and the valve seat sealing surface, and the good coincidence degree and the sealing effect are ideal. 
 5. The medium can pass through the gate valve in any direction from both sides and is suitable for the pipe acting on the medium which may change direction Closure device.


 A, less product connections, the overall good steel. 
 B, the closure of fast. 
 C, the opening limit mechanism is convenient, flexible and accurate. 
 D, small size, beautiful appearance. 
 E, simple operation, labor-saving, easy maintenance. 
 F, fluid resistance is small, the sealing surface erosion by the medium small. 
 G, medium flow restrictions do not love, do not disturb the flow, do not reduce the pressure.
