　　Oil seals are critical components in mechanical systems, serving essential roles across various industries, from industrial machinery to household appliances. But what materials are oil seals made from, and what specific functions do they serve? Let’s explore. 　　Common Oil Seal Materials 　　The selection of oil seal materials depends on the operational environment and requirements. Common materials include: 　　Nitrile Rubber (NBR): Suitable for temperatures between -40°C and 125°C, offering good oil resistance and wear properties. 　　Fluororubber (FKM): Known for its high-temperature resistance, FKM works in temperatures from -20°C to 250°C, ideal for high-heat environments. 　　Silicone Rubber (VMQ): Offers a wide operating temperature range from -60°C to 225°C, excelling in low-temperature conditions. 　　Acrylic Rubber (ACM): Resists heat and oil well, functioning in temperatures from -25°C to 150°C. 　　Polyurethane (PU): Exhibits excellent wear resistance, suitable for moderate environments with temperatures between -20°C and 120°C. 　　Polytetrafluoroethylene (PTFE): Renowned for its outstanding chemical and temperature resistance, PTFE operates between -65°C and 260°C. 　　Functions of Oil Seals 　　The primary function of oil seals is to prevent the leakage of lubricating oil, ensuring efficient lubrication between mechanical parts. Additionally, they block external contaminants like dust or dirt from entering the machinery, thereby enhancing performance and extending the lifespan of the equipment. 　　Applications of Oil Seals 　　Automotive and Motorcycle Engines: Oil seals are used to seal crankshafts and camshafts, preventing oil leakage in the engine. 　　Agricultural and Construction Equipment: Oil seals play a crucial role in sealing transmission systems in machinery such as excavators and bulldozers. 　　Industrial Gearboxes: Oil seals ensure proper lubrication in gear systems, reducing wear caused by friction during operation. 　　Hydraulic Systems: Oil seals maintain the stability of hydraulic components, such as pumps and motors, by preventing hydraulic fluid leakage and ensuring optimal performance. 　　In conclusion, oil seals are indispensable in modern machinery. Their proper application not only enhances the efficiency of equipment but also extends its operational life, ensuring long-term reliability and stability.

Valve Size: DN40-DN1200.  Pressure Rating: PN10-PN250. Material:GS-C25;1.0619;GP2 , 40GH,1.4308;1.4408,1.4571,1.4581,S31803 and Other Alloy Steel Design & Manufacture: DIN EN 12516-1;BS EN 12516.1;BS EN ISO 10434,EN1984 Face to Face Dimension: DIN EN558-1,EN12982 Flange Ends Dimension:EN1092 Test & Inspection:EN12266 End: RF,RTJ,BW Drive Device: Handwheel,Chainwheel,Bevel Gear;Electrical & Pneumatic Actuator Features Leflow provides high performance gate valve products, including Wedge gate valve, Pressure seal gate valve, Knife gate valve, Flat gate valve and Bellow seal gate valve. The OS&Y stem is most popular, but Non-Rising Stem type is also in our scope. Both flexible and Solid disc are available. For big size or Big pressure valve, By-pass design is optional.Below seal gate valve also falls in our ability. A gate valve, known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance. The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. CAST STEEL GATE VALVE-DIN is usually for working condition in which the valve is not opened or closed frequently, and supports gate fully open or fully closed. It’s not suitable for adjustment or throttling. Gate valve includes three types-Wedge gate, Knife Gate and Parallel Gate. The disc of Wedge gate valve comes with Solid Type and Flexible Type. Flexible Wedge Gate Valves design consists of two independent and flexible wedge halves, that allow a relative movement to accommodate changes in the body seat angles. Solid wedge is designed in one-piece model while flexible wedge offers a wedge shape for both seats.

Valve Size:  DN25 – DN1000  Pressure Rating: PN10 Material: Ductile Iron(GGG50),Aluminum, WCB and Stainless Steel Operation: Manual, Pneumatic and Electric; Ends Dimension:DIN2533 BS4504,JIS B2212,ANSI B16.5 Test & Inspection: EN12266, API 598 Leflow’s high quality Pinch Valve is the ideal solution for shutting off and controlling abrasive, corrosive and fibrous media such as emulsions, silt, dust,gaseous substances, compressed air, powdery materials and particles. It has following options: 1.Body can be made of Ductile Iron, WCB,Aluminium and other Stainless Steel; 2.Operation can be Manual, Pneumatic and Electric; 3.Sleeve can be made of EPDM,NBR,NR(Natural Rubber) and so on. Pinch valve, also known as pressure valve,is a valve that uses manual, pneumatic, electric and other driving methods to squeeze the internal rubber tube to On-off or regulate the flow. Pich valve is composed of upper and lower valve body, rubber sleeve, Upper and lower stem, upper and lower gate, left and right guide post and other parts; As the core component, the rubber sleeve is usually composed of an inner layer, an outer layer and a reinforcing fiber, and is formed by vulcanized rubber. Common rubber sleeve materials are natural rubber, fluorine rubber, neoprene rubber ball, EPDM rubber, nitrile rubber, food grade rubber ball and so on. When the hand wheel is rotated clockwise, the size of the pinch valve stem simultaneously drives the upper and lower valve plates to compress the rubber sleeve, and the valve is closed. When it is turned anti-clockwise, the valve is opened due to the joint action of the elasticity of the rubber sleeve and the pressure of the medium. The gate moves up and down between the left and right guide to complete the valve opening and closing; During the closing, Once it feels the connection between upper and lower sleeve, then stop continuing to close, More torque will damage the sleeve. The Pinch valve can be installed in any direction on the pipe, and there is no medium flow limit. After using for a long time, if the rubber sleeve is found to be worn and leak happens, just disassemble the upper and lower valve body and replace it with a new rubber sleeve. The valve body can be reused and the maintenance cost is very low. Manual Pinch Valve Leflow’s Manual Pinch Valve is a reliable, low-maintenance, and cost- effective valve designed for challenging slurry, abrasive, and corrosive chemical applications across various industries. The 100% full bore design eliminates any dead points or gaps, seats, or bearings where slurries might stagnate and affect operation, or even lead to valve failure. The manual pinch valve features a bi-directional drip-tight closing function, and its design meets face-to-face dimensions identical to gate valves, plug valves, and ball valves (DN25 – DN1000). They are designed with flange connections conforming to EN12266, API 598 standards, or DIN2533 BS4504, JIS B2212, ANSI B16.5.

Test & Inspection: EN12266 Face to Face Dimension(Flanged): DIN3202 F6 End: BSP acc.to ISO228-1, Flange EN1092-2 PN16 and AS4087 Features: Leflow’s is manufacturing ball check valve with Flanged and Screwed ends, and options are as following: 1.DN15 to DN50 can be Screwed, and DN40 to DN600 are commonly flanged ends; 2.The coating of ball can be NBR or EPDM; 3.All sizes of valves are Fusion bonded epoxy coated; 4.Full bore for all sizes; The cast iron check valve is usually used to control the one-way flow of fluids. It usually consists of a valve body, ball, spring, and sealing components.This kind of valve is suitable for medium and small diameter pipelines and widely used in industrial systems such as water supply, drainage, heating, and cooling. Its main characteristics are as following: 1.Simple and compact structure: fewer components, easy to install and maintain; 2.Low Pressure drop, Minimum backpressure for tightness 0.3bar; 3. Quick close:The check valve can quickly close when the fluid flow direction changes, preventing backflow and protecting the safe operation of the pipeline system; 4. Good sealing performance: The ball is encapsulated with soft rubber, which can achieve Zero leak; 5. Silent operation the sound of ball touching the seat is very small,as soft rubber covering the ball; 6. The ball can self-Cleaning; 7. Horizontal and vertical installation in the pipeline 8. Keep valve on Pipeline to change ball or clean valve interior
