Processes for Manufacturing Waits Fluorine-Lined Valves
1. Isostatic Molding Method
The isostatic molding method refers to a forming process that achieves the lining effect under the condition of equal pressure difference between the inner and outer walls of all lined parts of the workpiece. The biggest difference between this molding method and traditional compression molding lies in achieving the condition of equal pressure difference between the inner and outer walls of the workpiece's lined parts during the pressing process.
2. Compression Molding Process
The compression molding process employs medium-particle-size suspension polytetrafluoroethylene (PTFE) resin as the material. Molding initiates at approximately 19-22°C; higher temperatures may lead to material agglomeration, and precise temperature control is crucial to eliminate internal stress during this stage. Pressure is typically regulated at 350 kg/cm² and sustained according to the workpiece's size and shape. The process concludes with a three-stage sintering procedure—heating, holding, and cooling—after which machining is performed to achieve the desired specifications.
3. Transfer Molding Process
The transfer molding process involves placing the quality Waits valve body and the lining material together in a high-temperature sintering furnace for heating. After heating to a certain temperature, the body is taken out, and the lining material is slowly transferred to all parts of the lined body under the pressure of a press. This forming method is called transfer molding.

Fluorine-lined valves are classified as follows:
Pinch valves, lined diaphragm valves, lined pneumatic butterfly valves, lined pneumatic ball valves, lined check valves, fluorine-lined globe valves, lined plug valves, lined wedge gate valves, diaphragm valves, butterfly valves, ball valves, swing check valves, ball core check valves, pneumatic rubber-lined valves, fluorine-lined plastic diaphragm valves (normally closed type), straight-through fluorine-lined diaphragm valves, packed adjustable fluorine-lined plastic butterfly valves, fluorine-lined plastic globe valves, etc.

Under the global wave of development, infrastructure construction continues to advance, with thriving industries such as petroleum, chemicals, and pipelines driving increasingly widespread applications of fluorine-lined valves. As the global economy grows, the market demand for these valves continues to rise. The industry faces disorderly practices. Some enterprises, seeking profits in intense competition, resort to cutting corners on material quality and product weight, substituting inferior materials to reduce costs. Such unfair price competition disrupts market order and undermines the long-term healthy development of the sector.Waits Valve guarantees the quality of our valves.The fluorine-lined valve market presents both opportunities and challenges. With the surge in global enterprises, supply-demand contradictions have become prominent, and the industry is undergoing a clear reshuffling trend. Nevertheless, untapped potential remains in niche sectors. Looking ahead, digital technologies will emerge as the core competitive advantage for enterprises striving to capture market share.WAITS Valve remains committed to delivering reliable valves and exceptional full-cycle services.
