Overview of Z41F fluorine lined gate valve:
The valve is one of the most common with open and close the valve by two side sealing a wedge shaped medium to connect or disconnect the line, wedge gate valve does not allow for trace open throttle device in the pipeline, so as not to damage the sealing surface and accelerate the erosion caused by the medium high speed flow. FEP (F46), PCTFE (F3) fluorine valve which is used in various concentrations of -50 ~150 DEG C of the aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acid, strong oxidizing agents, the use of strong organic solvent FEP is also applicable to various concentration and other pipeline corrosive gas and liquid medium.
Z41F fluorine lined gate valve features:
The 1 valve body and a flat circular shape: two GB valve with round, ANSI pound valve DN is less than or equal to 300Lb with DN = 400Lb flat, with round, valve body, valve cover, valve stem cavity and the outer surface of the gate in direct contact with the media components, all were lining FEP (F46) and fluorine plastic;
2 sealing pair is FPF (F46) / FEP (F46) or other material combination, friction coefficient is small, the opening and closing torque is low;
3 packing with PTFE (F4) standard packing, good sealing performance, easy maintenance and replacement;
4 with a flexible gate, can compensate the gate sealing surface and the valve seat sealing surface between the wedge angle deviation, good agreement, sealing effect is ideal;
5 medium can be adopted from both sides of any direction through the gate valve, suitable for the direction of the media may change the role of the pipeline opening and closing device.
