First,Lining the gate valve Products:
Lining the gate valve product is one of the most see the opening and closing valves, the use of both sides of the seal was wedge-shaped gate to turn on or cut off the medium in the pipeline, wedge gate valve does not allow trace Open in the pipeline for the throttling device, so as to avoid high-speed flow of media erosion and speed up the sealing surface damage. FEP, Fluoride and various organic acids, Also suitable for a variety of concentrations of strong alkali organic solvents and other corrosive gases, liquid medium used on the pipeline.

Lining the gate valve used in the sealing of the FEP or other materials, the friction coefficient is small, low opening and closing torque; packing with PTFE standard packing, good sealing performance, easy maintenance and replacement; with a flexible gate, And the sealing surface of the valve seat between the wedge angle deviation, good fit, sealing effect is ideal.

Two, Lining the gate valve Applications:
Z41F3, Lining the gate valve applicable aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various concentrations of various -50 ℃ ~ 150 ℃ organic acids, strong acids, strong oxidants, FEP Also suitable for a variety of concentrations of strong alkali organic solvents and other corrosive gases, liquid medium used on the pipeline.

Body with flat and round two shapes: GB GB valve with round, ANSI pounds of American standard valve DN ≤ 300Lb with flat body, DN ≥ 400Lb with round body.

Three, Lining the gate valve structural features:
1, the valve body, the valve cover and the ram, the valve stem and other parts of the surface directly contact with the media, all lining FEP (F46) and other fluorine plastic;
2, Sealing (F46) / FEP (F46) or other materials, the friction coefficient is small, the opening and closing torque is low; 
3, the filler is PTFE (F4) standard packing, the sealing performance is good, the maintenance is easy to replace; 
4, with elastic ram, can compensate the wedge sealing surface and valve seat sealing surface wedge angle deviation, good compliance, ideal sealing effect;
5, the media can be from both sides of the direction through the gate valve, the medium direction may be used to change the role of the pipeline on the role of the opening , the valve can be used to compensate for the gap between the sealing surface and the valve seat sealing surface deviation, good fit, good sealing effect; Closed device.

A, product connector less, the overall good steel. 
B, closing speed fast. 
C, opening limit mechanism is convenient, flexible and accurate. 
D, compact, beautiful appearance. 
E, simple operation, effort, easy maintenance. 
F, the fluid resistance is small, the sealing surface by the medium erosion small. 
G, media flow does not love the limit, no spoiler, do not reduce the pressure.

Four, Lining the gate valve standard:
design and manufacturing standards: GB / T 12234 
structural length standard: GB / T 12221-2005 
connecting flange standard: GB / T 9113 
pressure temperature grade: GB / T 12224-2005 
test inspection standards: GB / T 13927-2008

Five, Z41F46 lining the gate valve parts and conditions:

1, the valve body material: carbon steel, stainless steel. [Optional] 
2, sealing material: the whole flow channel tetrafluoroethane. 
3, packing: PTFE. 
4, stem material: stainless steel 304, stainless steel 316, stainless steel 2cr13.

Six, Lining the gate valve main shape connection size
