Type OSE slam-shut valve is used to rapidly cut the gas flow during an overpressure or underpressure event. It is ideal for gas applications requiring positive shutoff protection, tight accuracy, fa
Features
- Overpressure and Underpressure Protection
- High Shock and Vibration Resistance - Type OSE incorporates a two-stage tripping mechanism that significantly reduces nuisance tripping caused by vibrations or inlet pressure variations commonly experienced by other shut-off valves.
- High Accuracy - Maintains up to ±1% accuracy regardless of inlet pressure, flowrate and the size of the slam-shut.
- Easy In-Line Maintenance - Top entry design reduces maintenance time and manpower requirements; parts can be inspected and replaced without removing the body from the line.
- Water Tight - Type OSE is water tight to 10 ft / 3.0 m.
- Positive Shutoff - After closing, the slam-shut valve stays closed until the system is shut down and the valve is manually reset. An O-ring on the valve plug seal provides tight shutoff.
- Remote Alarm Capability - A limit switch is available that detects when the Type OSE slam-shut valve is tripped.
