Soft seat ball valve ptfe.
The seat has high mechanical strength and abrasion resistance.
Both of them offers excellent sealing performance and have their unique and irreplaceable advantages and inevitably due to the shortcomings costs abrasion resistant performance working conditions of different materials metal seated valves and soft seated valves both.
Soft seats however aren t suitable for processing abrasive or dirty fluids.
R ptfe r 15 glass reinforced ptfe suitable for temperature 50 f to 450 f chemical resistance is compatible to virgin ptfe with better wear factor.
The ball seats are used in class jis 10k 20k asme class 150300 ductile iron stainless steel and carbon steel floating ball valves.
Metallic 50 nylon special nylon seats are offered for higher pressure and lower temperature.
The soft seated ball valves are factory tested.
Cavity filled seats are standard on our sanitary line of ball valves in both two and three way.
C f ptfe carbon fiber filled polytetrafluoroethylene resin this ball seat is made of ptfe reinforced with carbon.
These valves are appropriate for applications in which chemical compatibility is crucial and in situations where having the tightest seal is important.
They re great for applications where chemical compatibility is important and where the tightest seal is key.
These parameters are guidelines and customers are responsible for materials of construction being compatible with their valve application.
The most common fluoropolymer application is in process valves.
Soft seated ball valves.
Soft seats can break down in these conditions.
Seats are hand lapped to the ball as individually matched sets assuring line contact between valve ball and seats resulting in smooth operation and tight shut off class.
