低温减压阀主要在低温贮槽上及管路系统中低温液体气体的压力调节，其利用弹簧和不锈钢膜片来调节阀后压力，使压力保持在一定范围内。
The Model 1000HP is a high capacity, high pressure regulator used to control downstream pressure between 10 and 300 psig (0.69 and 20.7 Barg). Available in sizes from 1/2" through 2" (DN15 through DN50).
The unique internal design allows use in a multitude of applications, including process fluids that normal pressure reducing regulators can not match. The most versatile self- contained, pressure reducing regulator available to users.
FEATURES
Streamlined Flow Path：
Straight-through flow path reduces internal turbulence and resistance to flow, increas ing stability and capacity.
High Inlet Pressures:
Standard construction allows inlet pressures up to 740 psig (51.0 Barg).
High Outlet Pressures:
Controlled outlet pressure up to 300 psig(20.7 Barg).
High Pressure Drop：
Standard construction with extended guiding allows pressure drop up to 650 psid
(44.8 Bard). This regulator is routinely applied in severe service conditions
Flow-to-Open Plug：
Provides unmatched rangeability - far greater than competitive flow-to-close
designs. Highly stable at either high or low flow rates.
Versatility：
Four body materials and nineteen trim ma terial selections allow usage in a multitude of various fluids. Optional constructions extend the capability.
Protected Diaphragm Zone:
Internal arrangement isolates the dia phragm from direct impingement, negating any flow induced instability at either low or high flow rates. Allows incorporation of dynamic boost from jet section. Uniformly registers pressure on the diaphragm.
Diaphragm Travel Stops:
Incorporates mechanical stop in spring chamber to limit diaphragm uptravel and in body for downtravel, minimizing po tential int ernal damage from over-travel conditions.
APPLICATIONS
Used primarily in utilities services - saturated steam, superheated steam, industrial gases, fuel oils, compressed air, or water condensate. Also used in sour gas, chemical and other process services.
