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, fast speed of response, and high shock and vibration resistance. The top entry design makes in-line maintenance easy, saving time and manpower requirements.
OSE 型快速切断阀在出现过压或失压情况下，快速切断气流。 它是需要完全切断保护、精确密闭、快速响应、抗高冲击和抗震气体应用的理想选择。 顶装式设计，易于在线维护，节约时间和人力要求。美国FISHER费希尔签约代理商广州奥丽斯特燃气设备有限公司咨询电话：零二零-捌贰壹柒捌柒伍叁 13423610804 刘小姐
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 卤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.
功能
过压和失压保护
抗高冲击和抗振——OSE 型含有一个二级跳闸机构，大大减少了由于振动或入口压力振动引起其他切断阀产生的不必要跳闸的情况。
高精度——维持高达 ±1% 的精度，无论入口压力、流率以及快速切断装置的尺寸如何。
易于在线维护——顶装式设计减少了维护时间和人力需求，无需将阀体从管线上拆下即可检查和更换零件。
水密 ——OSE 型水密性最高可达 10 ft / 3.0 m。
完全切断——闭合后，快速切断阀保持闭合，直至系统关闭，手动重置阀门。 阀塞密封上有一个 O 型圈，保证切断密闭性。
远程报警功能——提供一个限制开关，可检测到 OSE 快速切断阀跳闸的情况。
