Soft seat options for ball valves.
Soft seated ball valves.
Line contact between valve ball and seats resulting in smooth operation and tight shut off class.
Thrust washers and back up rings.
These valves are appropriate for applications in which chemical compatibility is crucial and in situations where having the tightest seal is important.
The ball seats are used in class jis 10k 20k asme class 150300 ductile iron stainless steel and carbon steel floating ball valves.
These parameters are guidelines and customers are responsible for materials of construction being compatible with their valve application.
Soft seats are generally made of thermoplastic materials like ptfe.
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.
The soft seated ball valves are factory tested.
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 can break down in these conditions.
50 316 powder combined with 50 ptfe.
Seats and seat inserts.
Almost all the industrial valves are metal seat and soft seat available.
C f ptfe carbon fiber filled polytetrafluoroethylene resin this ball seat is made of ptfe reinforced with carbon.
Metallic 50 nylon special nylon seats are offered for higher pressure and lower temperature.
Ansi asme b16 34 should be considered when selecting valve materials of construction.
Soft seated ball valves.
Soft seats however aren t suitable for processing abrasive or dirty fluids.
They re great for applications where chemical compatibility is important and where the tightest seal is key.
Apv offers metal seats in different classes of shut off including class i v and vi.
However soft seats are not recommended for process fluids that are dirty or abrasive.
The seat has high mechanical strength and abrasion resistance.
Please consult a t controls for seat material selection for your unique applications.
The most common fluoropolymer application is in process valves.
