Low Temperature Resistant Valve Core
Tianjin TGE BIAM Graphene Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of low temperature resistant valve core in China. Welcome to buy bulk durable low temperature resistant 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
Sealing reliability at sub-zero temperatures is a distinct engineering challenge. Standard elastomers stiffen as temperature decreases; below each compound's glass transition temperature, the rubber loses elasticity and the sealing contact force drops below the level required to maintain a leak-free interface. Low temperature resistant valve cores use compounds specifically formulated to retain elastic compliance at operating temperatures that would cause standard grades to harden and fail.
We manufacture low temperature resistant valve cores in NBR (to −50°C with special formulations), HNBR (to −40°C), fluorosilicone (to −50°C), and polyurethane (to −40°C). Compound selection for each application depends on the medium, the minimum operating temperature, and the chemical environment.
Introduction to Performance
|
NBR Low-Temperature Grade |
Standard: −40°C; Special formulation: −50°C |

HNBR Low-Temperature Grade |
−40°C with maintained oil resistance and mechanical strength |
|
Fluorosilicone (FVMQ) |
−50°C with fuel and oil resistance retained |
|
Polyurethane |
−40°C; excellent flexibility retention at low temperature |
|
Validation Method |
TR10 / Tg testing |
Introduction to Processing Techniques and Materials
Low-temperature performance is achieved through compound formulation, not post-processing.
All low-temperature resistant valve cores are cold-flexibility validated by TR10/Tg testing. Parts destined for arctic or cryogenic-adjacent service are tested at the specified minimum operating temperature before shipment.
Typical Applications
Typical Applications for Low Temperature Resistant Valve Core include:
Arctic oil and gas production wellhead and gathering valves
Cold-climate outdoor pneumatic and hydraulic control systems
Cryogenic plant auxiliary valve assemblies
Refrigeration system control valves (industrial and commercial)
Advantages
A valve core rated to −40°C on a datasheet and a valve core that maintains sealing integrity at −40°C in your specific installation are not the same thing. The difference lies in compound formulation, cold-flexibility testing, and the absence of design shortcuts.
At TGE, we characterize the cold performance of our low-temperature valve cores at the compound level, test parts at the target minimum temperature, and provide test data. Where standard grades fall short, we reformulate.
FAQ
Q: What is the temperature that your rubber-metal bonded valve core can be used for?
