Carbon Steel Full Bore Pressure Relief Safety Valve DN15-DN300 1.0-32.0 MPa for Industrial Applications
This safety valve provides essential over-pressure protection by automatically opening to fully discharge excess pressure and closing when pressure returns to safe levels, preventing equipment damage and ensuring operational safety.
Designed as the optimal solution for over-pressure protection, this safety valve automatically activates when medium pressure exceeds the preset limit, fully discharging to prevent pressure escalation. It automatically resets when pressure drops to the safe setting value.
