Research and Development
We propose new air‑conditioning and refrigeration components
that meet customer needs while taking into account energy savings,
global warming prevention, and other environmental considerations.
Composite‑type check valve
A composite‑type check valve in which three or four check‑valve elements are built into a copper pipe, allowing compact and space‑saving configurations such as bridge circuits. Compared to combining existing two‑way check valves with piping, it requires fewer connection points and offers improved airtightness and reliability.
In advancing research and development based on a market‑in approach, our sales, production,
and R&D divisions work together as one:
☆ Expanding our core technologies and pursuing their limits
☆ Actively taking on challenges in new business fields
Through these efforts, we aim to meet the needs of our customers.

Service valve for new refrigerants
We offer a full lineup covering nominal diameters from φ1/4 to φ3/4 with flare connections for external piping and brazed connections for internal piping. For φ7/8 to φ1‑1/4, we provide flange connections for external piping and brazed connections for internal piping, all designed with low pressure loss, high durability, and ease of installation in mind.
