Product Introduction
HVAC valve cores control refrigerant, chilled water, hot water, and condenser water circuits in commercial and industrial heating, ventilation, and air conditioning systems. The demands of HVAC service differ from industrial process applications in several respects: operating pressures are moderate, but the range of media - refrigerants, glycol solutions, chilled water, and condenser water with biocide treatment - requires careful compound selection. Seasonal temperature cycling, UV exposure in rooftop installations, and multi-year service intervals without maintenance access place additional demands on material stability.
Neoprene and EPDM are the standard compound choices for HVAC service; NBR, HNBR & FKM are used in applications involving oil-contaminated refrigerants. We manufacture across this full compound range.
Introduction to Performance
|
Operating Temperature |
CR (Neoprene): −40°C to +120°C; EPDM: −45°C to +150°C; NBR: −40°C to +70°C |
|
Refrigerant Compatibility |
NBR/HNBR/FKM: compatible with R-22, R-134a, R-410A (confirm with specific refrigerant and lubricant) |
|
Compression Set |
Low - critical for maintaining seat-tight shut-off in zone control valves over multi-year service |
Introduction to Processing Techniques and Materials
HVAC valve cores require consistent sealing performance over service intervals that may extend five to ten years without maintenance. Compression set is therefore a primary compound specification parameter - a valve core that gradually loses seating force over time will eventually fail to achieve shut-off, often without a distinct failure event that triggers maintenance.
Typical Applications
Typical Applications of HVAC valve cores include:
Chilled water and condenser water two-way and three-way control valve cores
Fan coil unit and air handling unit zone valve cores
Heat pump refrigerant reversing valve sealing elements
Cooling tower flow control valve cores
Underfloor heating manifold control valve components
District heating and cooling network isolation valve cores
Advantages
HVAC valve cores are not high-complexity components, but they are long-service, often-inaccessible components where early failure is disproportionately disruptive - a failed zone valve in a large building HVAC system can affect thermal comfort across an entire floor until a maintenance visit is scheduled. Consistent compound quality and low compression set over the rated service life are the performance attributes that matter.
We supply HVAC valve cores with compound formulations selected for the specific medium and service life, with cure parameter documentation and batch traceability. Pre-sales compound compatibility review will be helpful.
FAQ

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: Can we be your agent?
A: Yes, welcome. For the details, we can discuss in an individual meeting.
Q: What is your MOQ? Can I mix different styles to a start order?
A: The MOQ of PO is usually 100pcs, however it depends – it can be less than 100 pcs in some special cases. We can have a meeting to clarify if you need.
