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... -
Pressure Relief Valves - (1007 companies)Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line. Pressure relief valves are designed to provide protection from over-pressure in steam, gas, air, and liquid lines. Relief valves... -
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... -
Washers - (1241 companies)Washers are disks of metal or non-metallic material placed beneath a nut, an axle bearing, or a joint, to relieve friction, prevent leakage, isolate, prevent loosening, or distribute pressure. Washers are disks of metal or non-metallic material... -
Pressure Regulators - (1232 companies)These diaphragms may be made of elastomers or metal depending on the application. The sensing element combined with the loading mechanism sends the change in force to the control element. The control element is a valve that ultimately reduces the inlet... -
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)Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Check valves are self-activating safety valves...
-
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...
-
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...

Pacific International Bearing, Inc.
Self-Aligning Ball Bearings Self-aligning ball bearings are designed to accommodate angular misalignment between shafts and housing while still maintaining smooth operation. The fundamental design comprises two rows of balls, enabling them to operate with lower frictional resistance compared to other bearing types, resulting in reduced energy consumption and heat generation. The curvature of the inner and outer rings allows for the absorption of misalignment-induced stresses, enhancing the bearing 's longevity...

FHD Bearings Co., Ltd.
2306 Self-Aligning Ball Bearing Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Accommodate static and dynamic misalignment. Excellent high-speed performance. Excellent light load performance. Low friction (read more)Browse Ball Bearings Datasheets for FHD Bearings Co., Ltd. -

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...
