Rubber Coated Valve Core
Tianjin TGE BIAM Graphene Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of rubber coated valve core in China. Welcome to buy bulk durable rubber coated valve core in stock here from our factory. If you have any enquiry about customized service and quotation, please feel free to email us.
Product Introduction
TGE Rubber Coated Valve Core bonds an elastomeric sealing layer to a precision-machined metal substrate through vulcanization - permanently, not mechanically. The metal structure handles load and dimensional stability; the rubber layer delivers sealing compliance. Together, they serve wherever a single-material design falls short: hydraulic circuits, pneumatic controls, oil and gas flow lines, chemical processing, and water systems.
The rubber compound is the variable that governs compatibility. We develop and qualify compounds across the NBR, HNBR, FKM, FVMQ, CR, and PU families, covering operating temperatures from −50°C to +200°C. Material selection begins with the application - medium, temperature, and cycle conditions - not with a catalog default.
Performance Introduction
Operating temperature range is determined by compound selection:
|
Compound |
Temperature Range |
|
Nitrile (NBR) |
−40°C to +70°C (special grades to −50°C) |
|
Fluororubber (FKM) |
−15°C to +200°C |
|
Polyurethane (PU) |
−40°C to +70°C |
|
Fluorosilicone (FVMQ) |
−50°C to +200°C |
|
Neoprene (CR) |
−40°C to +120°C |
|
Hydrogenated Nitrile (HNBR) |
−40°C to +150°C |
All compounds are qualified for resistance to relevant media - petroleum oils, fuels, aqueous fluids, and industrial chemicals - matched to grade and formulation.
Introduction To Processing Techniques And Materials
For TGE Rubber Coated Valve Core, the compound formulation is handled in-house. ACN content in NBR grades, fluorine content in FKM, cure system, and filler loading are adjusted for each application rather than sourced from a fixed commercial grade.
Metal substrates - stainless steel, aluminum or copper - are treated to controlled surface roughness before bonding agent application. Adhesive systems are selected by elastomer type, a step critical in commodity production and the primary assurance to prevent adhesive interface failures in service.
Vulcanization is performed under documented temperature, pressure, and time parameters. Each production batch is traceable. Bond integrity is verified by pulling-testing; the acceptance criterion is cohesive rubber fracture, not interface separation.
Typical Applications
Rubber Coated Valve Core can be applied in hydraulic directional and relief valves. Pneumatic solenoid pilot valves. Oil and gas wellhead and pipeline controls. Chemical process isolation valves. Water treatment and irrigation control valves. Automotive fuel system components

FAQ
Q: Are you a manufacturer or trade company? Where are you?
A: We are manufacturer and our factory is located in Tianjin, China. We can design the rubber formulation, we can design the product structure, we have all the manufacturing and testing equipment in our factory (such as mixer, sand blasting, vulcanizing, rheometer, Mooney test machine, tensile test machine, low-temperature brittleness test machine, stiffness test machine, etc.).
Q: Do you make rubber compound by yourself or do you buy it from others:
A: We make rubber compound by ourselves, with multiple rubber mixing machines in our factory. We can also design the rubber formulation to meet the performance requirement of different applications.
