Features
Quick startup
Swiftly discharges the initial cold condensate and air.
Superb durability
The MIYAWAKI SCCV (Self Closing and Centering Valve) System has the effect of increasing durability by achieving soft closing during operation. Consisting of a free rotating valve that is centered and guided by the condensate flow, hence perfectly fitted in the valve seat even under extreme conditions of high pressure applications. This significantly reduces wear and erosion of the valve components.
Accurate operation in high pressure and high temperature ranges, and in the presence of superheated steam.
Easy maintenance
Internal components being grouped into units make it maintenance easy.
Typical applications
Suitable for steam main lines, trace lines, and other such applications.
