概述 Introduction
气动式温度自动调节阀（简称气动温控阀），用于船用动力装置、陆用动力装置冷却系统的高精控制，动作灵敏，控制精确，主要运用于淡水、海水和主辅机油系统冷却。温度任意设定，报警功能齐全，适合计算机集中控制。
Pneumatic Automatic Temperature Control Valve (Brief name is EATCV) is suitable for temperature control of marnr power unit, triphib power equipment refrigeration system temperature system of marrive & onshore power unit and also mainly suitable for coding of fresh water, sea water, system of main machinery and auxiliary machinery. Such as diesel engine, trubine, genetator or lubricant equipment etc. It has the features of quick reb highly accuracy, temperature setting at will and having alarm function, suctable to be controlled by computer.
