Learn more valve bushings, the fluid control needs to achieve through the valve bushing cut-off, regulation, diversion, counter current prevention, pressure stabilization, diversion or overflow pressure relief and other functions.

Usually in a right-angle turn design (90 degrees between full open and full close), the ball seal is secured between the two seats.Ball valves are widely used as open/close valves, which are characterized by quick opening and tight closing.

The fluid is only allowed to flow in one direction.Check valves are usually self-acting (e.g., automatic).Check valves should always be located at least three to five pipe diameters downstream of the pump outlet to avoid premature valve wear and to prevent flow back to the pump.Backflow preventer is another common check valve that consists of a series of double check valves designed to provide an additional safety precaution to prevent potentially contaminated fire fighting system water from leaking back into potable water.

A valve with a cylindrical or conical “plug” that rotates within the body to control the flow through the valve.A cock in a plug valve has one or more hollow channels that run through the side of the cock so that fluid can flow through the cock when the valve is open.Plug valves are designed to be simple, economical and often rugged, making them ideal for AWWA applications.

Usually for rectangular rotation design (full open and full closed between 90 degrees), you can choose rubber clad disc (rubber outer layer acting on the metal surface to achieve sealing) or direct metal disc and rubber seat interaction to achieve sealing.Eccentric design allows the disc to “CAM” into the seat for long service life, low operating torque and superior performance compared to conventional designs.Another type of butterfly valve is the “high performance butterfly” (HPBV), which uses metal or teflon seats and is suitable for higher pressure and more demanding services such as steam and process chemicals.

Multi-turn valves have a gate – like closure and two seats to close the valve.The direction of movement of the gate is perpendicular to the direction of the fluid (up and down).They are often referred to as OS&Y (Rising Stem Gate Valves) because of their screw-shaped stem design that protrudes beyond the top of the body.Gate valves are designed for fully open or fully closed positions and not for throttling devices.The most common gate valves are knife type and wedge type gate valves.The blade gate valve has a thin gate with a knife-like edge that cuts through solids when the gate valve is closed.Making it an ideal choice for grout applications in the mining, pulp and bill, and wastewater markets.The wedge valve has a wedge that is wedged into the rubber seat to close the valve tightly.Mainly used in water supply installations, including water sources for fire fighting systems as isolation and stop valves.

A combination of butterfly and check valves, these assemblies are known in the industry as “three-use valves”, providing cut-off (isolation), flow control (throttling), backflow prevention (check), and flow measurement (if balancing valves are included).The use of a three-function valve provides significant weight savings compared to traditional solutions.

Directional reversing valve is mainly used to change the direction of the flow of the medium in the pipeline, so that the two channels are connected to each other or cut off, play a reversing role.Unique flow channel design, as well as good wear resistance, is very suitable for the use of mine back fill system.

Design Of The Corrosion Resistance Bearing

The difference between stainless steel 304 valve bushing and 316 valve bushing

The quality of 316 stainless steel Valve Bushing is greater than 304 Valve Bushing stainless steel, 316 stainless steel on the basis of 304 into the metal molybdenum, this element can be more consolidated the molecular structure of stainless steel. 304 stainless steel bushing is commonly used in daily life, while 316 stainless steel bushing is used in valve, medical, or heavy industry equipment.

TEX steel bushing- based PTFE fabric self-lubricating bearings a high performance self-lubricating sliding material with a glass fiber reinforced carrying layer. The material is made of all kinds of high quality metals, and the surface is covered with PTFE and other additives, which are low friction and friction resistant. This material structure has higher bearing capacity and longer service life than the general three-layer composite bushing material. The base material is low carbon steel MS, stainless steel SS316L, etc. Mainly used in agricultural machinery, construction machinery, automobile chassis parts, ball valves, butterfly valves, water pumps and chemical industry and other heavy and low speed but can not refueling occasions.

The material is based on various high-quality metals, and the surface is covered with a low-friction and wear-resistant woven material mainly made of PTFE and other additives. This material structure has a higher bearing capacity and longer service life than general three-layer composite materials. Stainless steel-backed 304 bushing and Stainless steel-backed 316 bushings have different advantages: It is a self-lubricating, glass-fibre reinforced composite bearing material which is produced using a special winding technology. 304 stainless steel bushing processing performance is good. 316 stainless steel bushing has good corrosion resistance, atmospheric corrosion resistance, and high-temperature strength for valve bushing.
