SIGMA阀15RS150系列15RS150-203技术参数及介绍
SIGMA Valves在四十多年前开始生产专门用于石油和天然气行业的不锈钢气动和液压控制阀。SIGMA Valves起源于专门为海上环境中的安全系统自动化而设计的阀门，而不是用于石油/天然气行业的工业阀门。与小型工业型阀门相比，这些阀门具有更强大的设计特性和可靠性。
SIGMA主营产品有：
自动继电器
检查阀门
控制器单元
紧急关机设备
可熔装置
液压界面阀
液压调节器
手动继电器
压力传感器
快速排气阀
安全阀
沙探针
速度止回阀

SIGMA阀15RS150系列介绍
Sigma 2通易熔阀是二位、二通常闭、温度敏感的流量控制装置。高温或靠近火将熔化维持阀门常闭流路的固体共晶。当阀门受到超过驱动温度的热量时，将自动发生供排气流路。
易熔阀用于关闭或关闭安全系统执行器，以将潜在的燃料源与火灾隔离。
可熔阀有四种常见温度：158 ℉、203 ℉、255 ℉ 和 281 ℉。 其他温度可通过特殊订单查询获得。
Sigma 2-Way Fusible Valves are two position, two- way normally closed, Temperature Sensitive flow control device. Intense heat or close proximity to a fire will melt the solid Eutectic that maintains the valve's normally closed flow path.When the valve is subjected to heat that exceeds the actuation temperature, a Supply-to-Exhaust flow path will occur automatically.
Fusible Valves are used to shut-in or close safety system actuators to isolate potential fuel sources from fire.
Fusible Valves are available with four common temperatures:158℉, 203℉, 255℉ and 281℉. Other temperatures are available through special order inquiry.
