What we do

High Quality Metallic Compressor Valve Parts
KB Delta manufactures and stocks a complete range of metallic compressor valve plates and rings for the air and process gas compressor, refrigeration, and PET industries. We use the highest grade Stainless Steels and latest laser profiling equipment to manufacture stress-free steel compressor valve components. After the parts are cut, KB Delta sends the metallic parts through a series of proprietary procedures and finally through quality control tests to ensure the customer gets the highest quality metallic compressor valve parts.
Our process
-
The Right Stainless Steel
KB Delta selects only the highest grade 410 Stainless Steel for its metallic plates (valve, damping, cushion and rings) and 420 Stainless Steel for spring and wafer plates - same as the OEMs. Grade 410 and 420 are selected due to their corrosion resistance, strength and hardness properties. KB Delta only uses these metals in their stress-relieved and hardened condition. Other steels are available for custom orders and special parts on request.
-
State-of-the-art Process
KB Delta uses the latest laser profiling equipment to manufacture stress-free steel compressor valve plates and rings. Our state-of-the-art laser metal cutting system guarantees precisely cut metallic components. We also implement a proprietary metal plate finishing and flattening process to ensure the highest quality steel parts in the industry. These practices guarantee all KB Delta’s metallic compressor valve parts meet and exceed OEM standards.
