Valves
1. Service valves

RA Needle Valve
-
Available in sizes 1/4 to 5/8, with a full range of flare‑type connections and piping connection options.
PA Needle Valve
-
Offered with flare connections for 1/4 to 3/4 sizes, and flange connections for 7/8 to 1‑1/4 sizes. Designed for low pressure drop, high durability, and serviceability.
Ball Valve
-
Uses a dual‑valve (2‑in‑series) configuration combining 3/8 + 5/8 and 3/8 + 7/8 sizes to improve installation flexibility. Additionally, single‑valve units are available with flange connections in 7/8 and 1‑inch sizes.

2. Check valves
2‑Port Check Valve
-
We have developed a refrigerant check valve with the smallest number of components in the industry, something not available from other manufacturers. To simultaneously achieve high sealing performance and long‑term durability, the valve uses specially designed materials and an optimized internal structure. In addition, because it contains no brass components, it is fully compliant with RoHS regulations with no issues.
