Ball Valves - (2114 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... -
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... -
Check Valves - (1951 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... -
Gas Valves - (535 companies)...requirements. Gas valves are available in most of the basic valve technologies such as ball, butterfly, plug, needle, and various check valve designs. They are used in many industrial, commercial and residential applications for on/off, modulating, and control... -
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... -
Solenoid Valves - (1022 companies)Solenoid valves are devices that use a solenoid to control valve activation. They are considered electromechanical control devices used to control liquid or gas flow. An electrical current runs through a coil to control the valve by moving a plunger...
-
Valve Actuators - (914 companies)...motion and operation style are important specifications to consider when selecting valve actuators. Valve Method of Control. Rotary motion valves (rotary valves) such as ball, plug, and butterfly valves rotate a quarter-turn or more from open to close...
-
Hydraulic Valves - (684 companies)Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves. In their unpowered state, hydraulic valves can be normally open (open...
-
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...
-
Control Valves - (1646 companies)...as throttling valves to control flow. Ball valves provide tight shut-off and control. They have high rangeability due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves. Plug control...

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...
