Description for Fisher OSE Slam-Shut Valve

Fisher™ Type OSE Slam-Shut ValveType 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, faFeaturesOverpressure and Underpressure ProtectionHigh 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.SpecificationsBody Sizes and End Connection StylesWCC Steel: 1 and 2 NPT; NPS 1, 2, 3, 4 and 6 / DN 25, 50, 80, 100 and 150; CL150 RF, CL300 RF or CL600 RFLCC Steel: NPS 8 and 10 / DN 200 and 250; CL150 RF, CL300 RF or CL600 RFCast Iron: 1 and 2 NPT; NPS 1, 2, 3, 4 and 6 / DN 25, 50, 80, 100 and 150; CL125 FFPressure RatingsMaximum Inlet Pressure: 101 bar / 1470 psig or max. body ratingMaximum Set Pressure: 101 bar / 1470 psig or max. body ratingMinimum Set Pressure: 10 mbar / 4.02-inches w.c.Maximum Shutoff Pressure Differential 100 bar / 1450 psigManometric Sensing Device SpecificationsSpring Ranges: 10 mbar to 72,9 bar / 4.02-inches w.c. to 1058 psigMaximum Sensing Inlet Pressure: 72,9 bar / 1058 psigSetpoint Tolerance: 0,004 bar / 0.058 psig to 12,0 bar / 174 psigMaximum Difference Between Overpressure and Underpressure: 33,0 bar / 479 psigTemperature Capabilities-30° to 82°C / -22° to 180°FPressure Sensing Connections1/4 NPTOptionsExplosion-proof switchNon-explosion-proof limit switchSolenoidAdditional manometric device for extra pressure sensingst speed of response, and high shock and vibration resistance.
