Ball Valves - (2115 companies)Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open... -
Check Valves - (1952 companies)The mechanics of check valve operation are relatively simple. Most check valves contain a ball that sits freely above the seat, which has only one through-hole. The ball has a slightly larger diameter than that of the through-hole. When the pressure behind... -
Butterfly Valves - (1270 companies)...little resistance to flow. These valves offer a rotary stem movement of 90 degrees or less, in a compact design. Unlike ball valves, butterfly valves do not have any pockets in which fluids may become trapped when the valve is closed. The valve operation... -
Gate Valves - (1164 companies)Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow. Gate valves (also known as knife valves or slide valves) are linear motion valves in which a flat closure element... -
Globe Valves - (794 companies)...to the valve seat allows or restricts flow. Ball disks fit into a tapered, flat-surface seat. The ball disk is best used in low pressure, low temperature systems. They can be used for throttling services but they are best used to start/ stop flow. Composition... -
Plug Valves - (476 companies)Quarter-turn plug valves use a cylindrical or tapered plug with a hole in the center to control straight through flow when in the open position. Plug valves, also called cock or stop-cock valves or quarter-turn valves, date back to ancient times...
-
Industrial Valves - (3054 companies)...and three designs for the disk: ball disk, composition disk, and plug disk. Throttling and regulating flow. High head loss due to flow direction changes. Less seat leakage than Gate Valve. Dynamics can create pulsation and damage trim/packing/actuators...
-
Balls and Sphere Shapes - (209 companies)Balls and sphere shapes are used in products that require a spherical component. Examples include bearings, ball screws, valves, flow meters, and gages. Balls and sphere shapes are made from materials such as glass, metals, plastics, and ceramics...
-
Ball Bearings - (766 companies)Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings types include radial ball bearings (deep groove and angular contact) and thrust ball bearings. Ball bearings are used to provide smooth, low friction...

Shenzhen Dechengwang Technology Co., Ltd
PTFE Ball Valve Seats A ball valve seat is an important component of a ball valve. The seat provides a surface for the ball to contact and seal against. The seat also helps guide the ball in the proper position to ensure proper valve operation. Advantages. The ball valve seat helps to distribute seating stress equally and is usually soft sufficient to adapt to the shape of the ball, resulting in a solid seal. Low friction, adequate ductility to produce a dependable seal, good stress rebound, high stiffness...
