Armstrong pressure reducing valve | Armstrong trap | Armstrong, trap 

 For decades, Armstrong has been dedicated to the research and sharing of energy-saving method of steam equipment. As many of our production, products / services as part of the pressure reducing valve and thermostatic valve provides reliable system solutions for the Armstrong more choices. 
 Steam, liquids and gases are usually high pressure to the final point. Used in these points, for the safety and efficiency reasons, and the use of the requirements of the pressure reducing valve will reduce the fluid pressure. Reducing valve a total of three types. 
 Direct acting pressure reducing valve. Simple pressure reducing valve, direct acting pressure reducing valve, with a flat diaphragm, or bellows. Because it is an independent structure, so no external sensing line is installed in the downstream. It is the smallest, using the most economic one, three kinds of pressure reducing valve designed for low flow. The accuracy of direct-acting valve is usually set for the downstream point of + / -10%. 
 Within the guide piston pressure reducing valve. This type of pressure relief valve set two valves - pilot valve and main valve - in one. The pilot valve design is similar to the Direct Acting. From the pilot valve exhaust pressure acting on the piston, the piston to open the main valve. If the main valve, can not directly open, this design will open the main valve inlet pressure. Therefore, this type of pressure reducing valve, direct acting pressure reducing valve, in the same pipe size, capacity and accuracy (+ / -5%) higher. Direct acting pressure reducing valve, pressure reducing valve internal perception of pressure, without externally mounted sensor line.
