In extreme operating conditions — high temperature, high pressure, and severe cavitation — reliability is everything.
The RAYS DN250 Multi-Stage Pressure-Reducing Control Valve is engineered to perform where others fail.
Forged from F91 high-temperature alloy steel, it delivers exceptional strength and creep resistance under +566°C and 32 MPa conditions.
Featuring a self-developed carbon-graphite cage sealing structure and extended bonnet design, it ensures zero leakage and stable operation under extreme heat and pressure.
