Pressure Reducing Valves for Air (with Built-in Separator & Trap)

A-COS-10

High precision pressure reducing valves for air, with built-in separator & trap.

Technologically advanced pressure reducing valve combined with condensate separator and air trap provides accurate control and air conditioning to maximize process system performance.

Benefits and Features

Supplies Air at Stable Pressure

Accuracy of pressure reducing valve's secondary set pressure is within ± 0.01 MPa. 
Even if the air flow (load) to the equipment or the pressure reducing valve primary pressure fluctuates, the Shock Absorbing Spherical Piston (SAS) supplies air at a constant pressure. Stable operation is possible through the supply of air at a stable pressure to the air-using equipment.

  • Supplies dry air 
    Condensate entrained inside the air piping is removed, enabling the supply of very dry air. 
    Product features a built-in Cyclone Separator with a 98% condensate separation efficiency. The separator improves the dryness of the air and removes scale entrained in the air. The condensate that is separated out is quickly removed through the built-in Free Float® trap. This allows for the prevention of the problems that would be caused if condensate were to enter the air-using facilities.
Easy to Adjust

Pressure adjustment is simple, and can be done by using the cover cap as the adjustment spanner.

Long Service Life

Rust presents a high risk to vital areas of the system. To eliminate this, all major valve components are made of stainless steel to prevent rust and corrosion. Additionally, the inclusion of a strainer in the piping installation prevents the inflow of rust and other debris, protecting the valve components and contributing to a long service life.

Application Areas

  • Air piping, air-using facilities.
