公司名称：上海爱泽工业设备有限公司

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 Valves began producing stainless steel pneumatic and hydraulic control valves dedicated specifically for the oil and gas industry over forty years ago. Sigma Valves originated as a company dedicated to valves specifically designed for safety system automation in offshore environments, not industrial valves converted for use in the oil/gas industry. These valves offer more robust design features and dependability than those found in smaller industrial-type valves.

SIGMA易熔塞产品描述

Sigma易熔塞在安全系统行业中通常被称为温度安全元件（TSE）。所有易熔塞都有可熔材料的核心，由于火焰或其他热源的高温而熔化。它们保持控制电路内的工作压力，直到超过易熔塞的温度。一旦低温易熔合金材料熔化，ESD控制电路就会失去工作压力，从而启动紧急关闭程序或安全阀关闭。易熔塞是大多数气动ESD控制电路不可或缺的一部分。

Sigma Fusible Plugs are commonly known as Temperature Safety Elements (TSE) within the safety system industry.All Fusible Plugs have a core of fusible material that melts due to intense heat of a fire or other heat source. They maintain operating pressure within the control circuit until the temperature of the Fusible Plug is exceeded. Once the low temperature fusible alloy material melts, the ESD control circuit experiences a loss of operating pressure, which initiates an Emergency Shutdown sequence or Safety Valve closure. Fusible Plugs are an integral part of most pneumatic ESD control circuits.
